Environment as a Contemporary Global Concern

The environment entered international politics as a technical annexe to development policy and has ended as one of its central organising questions. Its structure is unusual: the damage is physically global, the authority to act is nationally held, and the states best equipped to move are the least willing to. That mismatch — not scientific ignorance, and not a shortage of treaties — is what makes the environment the hardest of the contemporary global concerns.

The environment as a problem of international politics

Why the environment became a global concern

• Physical interdependence outran political jurisdiction. Sulphur emitted in Britain acidified Scandinavian lakes; a tonne of carbon dioxide warms identically whatever flag flies over the chimney.
  • Transboundary pollution was the first form recognised in law, in the Trail Smelter arbitration, which established that no state may use its territory so as to cause serious injury to another.
  • Global commons degradation is the harder second form: harm falls on a shared sink rather than an identifiable neighbour, so there is no injured state to bring a claim.
• Science acquired an institutional voice. The Intergovernmental Panel on Climate Change (IPCC), established in 1988, does not conduct research but assesses it, and its reports are approved line by line by governments — which makes them conservative but politically unignorable.
• Decolonisation reframed the question as one of distribution. Newly independent states insisted that a problem caused by industrialisation could not be solved by freezing them out of it.
• Movements globalised. National environmental publics generated transnational advocacy networks able to pressure their own governments from outside.
• The economics is unusual. Abatement is a global public good — non-excludable and non-rival — so the benefit of one state’s costly action accrues to all, including those that did nothing.

The physical trends that generate the politics

• Climate change is the organising trend, and the one that has pulled the others into a single negotiating agenda.
• Biodiversity loss is the second: species are disappearing fast enough that scientists describe a sixth mass extinction, driven by habitat loss, land-use change, pollution, invasive species and climate.
• Deforestation continues in the tropical belt, destroying carbon stocks and habitat simultaneously, and it is the trend where trade instruments have moved fastest.
• Ocean degradation compounds warming with acidification, deoxygenation, overfishing and plastic pollution; the 2023–25 global bleaching event affected an estimated 84% of coral reef area.
• Freshwater scarcity — aquifer depletion, glacial retreat, altered monsoon and snowmelt regimes — is the trend that translates most directly into distributional conflict.
• Land degradation and desertification and chemical and waste pollution complete what is now described as the triple planetary crisis of climate change, nature loss and pollution.

“Freedom in a commons brings ruin to all.” — Hardin

The global commons and the structure of the problem

• The global commons are the domains lying beyond any single state’s sovereign jurisdiction: the high seas, the atmosphere, Antarctica, and outer space, with the deep seabed added as the “common heritage of mankind” under the law of the sea.
  • Their defining feature is open access without an owner, which means neither the market’s price signal nor the state’s coercive authority operates on them by default.
  • The ozone layer and the climate system are commons of a special kind: they are sinks, and what is over-consumed is absorptive capacity, not a stock.
• Three overlapping analytical framings are used, and they are not identical.
  • The tragedy of the commons framing emphasises open access and the absence of enforceable property or governance rules.
  • The prisoner’s dilemma framing emphasises that mutual abatement is collectively best but individually dominated by defection, which is why binding commitments matter more than good intentions.
  • The collective action framing, in the tradition of Olson, emphasises group size: with nearly two hundred parties, each state’s marginal contribution is small enough that free-riding is rational and monitoring is expensive.
• The free-rider problem is empirically visible, not merely theoretical.
  • The Clinton administration signed the Kyoto Protocol and the United States Senate refused to ratify it, so the world’s then-largest emitter took the benefit of others’ reductions while accepting none of the cost.
  • Hence the search for near-universal participation: an agreement excluding major emitters is not merely incomplete but unstable, since participants’ costs rise while the benefit leaks away.

Sustainable development and its contested meaning

• The concept was popularised by the World Commission on Environment and Development, chaired by Gro Harlem Brundtland, whose 1987 report Our Common Future supplied the standard definition.

“Development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” — Brundtland Commission

• The definition does two political things at once, which is why it was adoptable.
  • It asserts intergenerational equity and, since the report gave overriding priority to the essential needs of the poor, intragenerational equity.
  • It refuses to choose between growth and conservation, letting North and South sign the same words meaning different things.
• Three standing critiques of the concept deserve statement.
  • Vagueness: with “needs” and “compromising” undefined, almost any policy can be called sustainable, and the term has been absorbed into corporate branding.
  • Weak versus strong sustainability: weak sustainability treats natural capital as substitutable by manufactured capital; strong sustainability denies substitutability for critical natural capital such as a stable climate or a species.
  • The growth objection, from ecological economists: that needs can be met indefinitely on a finite biophysical base is an assumption, not a finding.
• Sovereignty over shared water poses the same tension in another resource: upstream technological capacity — dams, diversion works, barrages — converts a shared river into unilateral leverage, and water law has never settled whether absolute territorial sovereignty or equitable and reasonable utilisation governs.

Theoretical frameworks for reading environmental politics

Hardin and the critique of him

• Garrett Hardin’s The Tragedy of the Commons modelled an open pasture on which each herder takes the full benefit of an extra animal while the cost of overgrazing is shared, so the individually rational act is collectively ruinous.
  • His remedy was “mutual coercion, mutually agreed upon” — either privatisation or state regulation of access.
  • Applied to the atmosphere, it explains why voluntary restraint is unstable and why enforcement, not exhortation, is the object of negotiation.
• The critique of Hardin now matters as much as the model.
  • He conflated an open-access resource with a common-property regime: a commons managed by an identifiable community with rules and sanctions is not open access, and historical English commons were regulated.
  • The framing has been used to justify enclosure, delegitimising the customary rights of pastoralists, fisherfolk and forest communities.
  • The account is static, ignoring communication, reciprocity and the shadow of the future.

Ostrom and the governance of common-pool resources

• Elinor Ostrom demonstrated empirically, across irrigation systems, fisheries, pastures and forests, that user communities have built durable self-governing institutions without either privatisation or state control.

“Communities of individuals have relied on institutions resembling neither the state nor the market to govern some resource systems with reasonable degrees of success over long periods of time.” — Ostrom

• Her eight design principles for enduring common-pool resource institutions are the practical core of the argument.
  • Clearly defined boundaries — who may withdraw, and from what.
  • Congruence between rules and local conditions, and proportionality between what a user contributes and what a user takes.
  • Collective-choice arrangements allowing those affected to modify the rules.
  • Monitoring by monitors accountable to the users themselves.
  • Graduated sanctions, so a first offence is not treated as a last one.
  • Accessible, low-cost conflict-resolution mechanisms.
  • Minimal recognition of the right to organise by external authorities.
  • Nested enterprises — for larger systems, governance layered from the local upward.
• Polycentric governance is her second contribution, and the one most directly relevant to climate.
  • Action proceeds at multiple, partly overlapping centres of decision — cities, provinces, firms, river basins, regional blocs — each producing local co-benefits that make action worthwhile without global reciprocity.
  • This reframes climate from one giant collective action problem into a nested set of smaller ones, several of which are tractable, and supplies the theoretical defence of the bottom-up Paris architecture and of subnational and sectoral coalitions.
• The limits of the transfer must be stated: her cases involve bounded groups, repeated interaction and visible cheating, while the atmosphere involves nearly two hundred states, opaque monitoring and effects displaced by decades.

Regime theory and institutional effectiveness

• A regime, in Krasner’s formulation, is a set of implicit or explicit principles, norms, rules and decision-making procedures around which actors’ expectations converge in a given issue-area.
  • Applied to climate: the principle is common but differentiated responsibilities; the norms include precaution and polluter-pays; the rules are reporting and review obligations; the procedures are the annual Conference of the Parties operating by consensus.
• Oran Young distinguishes a regime’s existence from its effectiveness, and effectiveness itself into several forms.
  • Output — did it generate rules and institutions? Outcome — did state behaviour change? Impact — did the problem improve?
  • The climate regime scores high on output, mixed on outcome and, on the emissions curve, poorly on impact.
• Peter Haas developed epistemic communities — transnational expert networks sharing causal beliefs and validity criteria — from the Mediterranean Action Plan, where scientists shaped state preferences before governments had settled positions.
  • The IPCC is the paradigm case in climate; the concept’s limit shows where science is settled but distributive stakes are large, since expertise narrows uncertainty without settling who pays.
• Design features that recur where regimes work: a framework convention followed by protocols, letting states accept the problem before the costs; differentiated obligations with financial transfers; and facilitative rather than punitive non-compliance procedures.

The IR traditions compared

Dimension	Neorealism	Liberal institutionalism	Constructivism	Marxist / world-systems
Core driver	Relative gains under anarchy	Absolute gains and transaction costs	Norms, identity, shared meanings	Capital accumulation and unequal exchange
Status of the issue	Low politics, subordinate to security	A tractable cooperation problem	A domain where interests are constituted, not given	A symptom of the capitalist world economy
Why cooperation happens	Only under a hegemon willing to bear costs	Regimes reduce uncertainty and lengthen the shadow of the future	Norm entrepreneurship, persuasion, socialisation	It largely does not; regimes manage rather than resolve
Reading of Paris	A lowest-common-denominator outcome with no enforcement	A workable regime using transparency in place of sanctions	The institutionalisation of a norm of universal responsibility	Ecological modernisation that protects accumulation
Key claim	Withdrawal of the hegemon disintegrates the arrangement	Information and reciprocity substitute for coercion	CBDR became part of Southern state identity	Ecological debt flows North

• The neorealist reading has real explanatory bite on the historical record.
  • At Rio the United States was both the most powerful state and the largest emitter, and the convention that emerged contained no binding reduction targets — the EU conceded because an agreement without the United States would have been ineffective.
  • Because American abatement costs exceeded European ones, a binding target meant competitive disadvantage: a relative-gains loss, not merely an absolute cost.
  • Timmons Roberts argues that the entanglement of climate with American anxiety about losing hegemonic status to China prevents any easy settlement of questions such as the just distribution of carbon space.
  • The high politics / low politics distinction also explains why environmental negotiation was long ignored by mainstream IR scholarship.
• The constructivist reading explains what neorealism cannot.
  • CBDR is part of the identity of developing states, not merely a bargaining position — the G77 and China treated it as non-negotiable long after the material distinction between rich and poor emitters had blurred.
  • The IPCC functions as an actor: by establishing intersubjectively shared facts it changes what governments can plausibly say.
  • Norm shift is observable: climate justice, loss and damage, just transition and phasing out fossil fuels all moved from activist vocabulary into treaty text within two decades.
• The Marxist reading supplies the distributive edge.
  • Ecological debt and ecologically unequal exchange: Northern consumption rests on extraction and waste absorption in the South at prices that do not reflect ecological cost.
  • The green capitalism critique: carbon markets and green finance make new commodities out of the atmosphere while leaving accumulation untouched.

The Anthropocene, planetary boundaries and their critics

• The Anthropocene thesis, popularised by Paul Crutzen, holds that human activity has become the dominant force shaping the Earth system, marking a departure from the Holocene.
  • It dissolves the nature–society binary and forces a rethinking of sovereignty and development through a planetary lens: if the atmosphere is a human artefact, territorial jurisdiction over environmental outcomes is a fiction.
  • In 2024 the relevant geological body voted against formalising the Anthropocene as an epoch, rejecting the proposed marker in the sediments of Crawford Lake and a start date in the early 1950s. The rejection was stratigraphic; the term survives as an informal “event” in wide use.
  • The counter-term Capitalocene, associated with Jason Moore, objects that “Anthropos” spreads blame across an undifferentiated humanity when the driver is a historically specific mode of production.
  • Plantationocene and Chthulucene, from Donna Haraway and collaborators, press the same objection from colonial agriculture and multispecies entanglement.
• The planetary boundaries framework, developed by Johan Rockström and colleagues, identifies nine Earth-system processes with thresholds defining a safe operating space for humanity.
  • The nine are climate change, biosphere integrity, land-system change, freshwater change, biogeochemical flows (nitrogen and phosphorus), ocean acidification, atmospheric aerosol loading, stratospheric ozone depletion and novel entities such as synthetic chemicals and plastics.
  • Seven of the nine are now assessed as transgressed, ocean acidification having been added to the list in 2025; stratospheric ozone is the one boundary moving back inside its safe zone, which is a direct result of the Montreal regime.
  • Its political value is to reframe policy as risk management against thresholds rather than incremental optimisation; critics object that global averages obscure regional variation and that boundary values embed contestable judgements.

Green political theory

• Deep ecology, associated with Arne Naess, distinguishes a shallow environmentalism concerned with pollution for human benefit from a deep ecology asserting the intrinsic value of non-human life and biospherical egalitarianism. Its implications — population reduction, radical simplification of consumption — draw the charge of eco-authoritarianism and indifference to the poor.
• Social ecology, from Murray Bookchin, locates the crisis in social hierarchy: domination of nature extends domination of human by human, so the remedy is confederal and directly democratic rather than spiritual.
• Ecofeminism connects the exploitation of nature to the subordination of women.
  • Vandana Shiva and Maria Mies argue that a “maldevelopment” model exported through colonialism and the Green Revolution displaced subsistence economies in which women managed biodiversity, water and seed.
  • Its weakness is the risk of essentialising women as closer to nature; the stronger version is materialist, resting on the gendered division of labour.
• Eco-socialism holds that an accumulation-driven economy cannot be greened at the margin, and that the metabolic rift between society and nature is intrinsic to capitalist production.
• Environmentalism of the poor, developed by Joan Martínez-Alier, is the most useful category for the Global South.
  • It distinguishes the cult of wilderness, the gospel of eco-efficiency and environmental justice movements driven by livelihood.
  • The poor mobilise not from post-material values but because a river, forest or fishery is their means of subsistence, which is why Southern environmental conflict is distributional.
  • Ecological distribution conflicts — over land, water, mining, waste siting — are its empirical object, counted in the thousands worldwide.

Growth, limits and degrowth

• The limits to growth tradition, from the Club of Rome’s system-dynamics modelling, argued that exponential growth on a finite base ends in overshoot and collapse; critics charged it with underestimating technological substitution and price-induced innovation.
• Ecological modernisation is the mainstream Northern answer: protection and growth are complementary, delivered through efficiency, innovation, internalising externalities, and decoupling output from resource use.
  • Absolute decoupling has occurred in several advanced economies; the contested question is whether it can be fast enough and global enough, and whether it survives correction for outsourced emissions embodied in imports.
• Green growth is the policy version now dominant in international institutions and underpins the renewable transition narrative.
• Degrowth, associated with Serge Latouche, argues for a planned reduction of throughput in rich economies, prioritising sufficiency over aggregate output. Its Southern reception is ambivalent: degrowth for the North is compatible with development for the South, but the vocabulary is unusable where per-capita consumption is a fraction of the world average.

Environmental multilateralism has produced an extraordinary volume of law and a global emissions curve that has still not bent. Output effectiveness is not impact effectiveness.

The international environmental regime: institutions and conventions

Stockholm 1972 and the birth of a policy field

• The UN Conference on the Human Environment, held at Stockholm in 1972, was the first global intergovernmental conference on the environment and created the field.
  • It produced the Stockholm Declaration, whose Principle 21 is the durable one: states have the sovereign right to exploit their own resources and the responsibility to ensure activities within their jurisdiction do not damage the environment of other states or of areas beyond national jurisdiction.
  • It established the United Nations Environment Programme (UNEP) at Nairobi — the first UN body headquartered in a developing country — with a coordinating rather than operational mandate and a chronically small core budget.
  • It set 5 June as World Environment Day and created the template of the mega-conference followed by a secretariat.
• Indira Gandhi’s address was the only one delivered by a head of government other than the host’s, and it defined the Southern position for a generation.

“Are not poverty and need the greatest polluters?” — Indira Gandhi

• Her argument was that degradation in poor countries is a symptom of underdevelopment, not of excess; that the North had industrialised without constraint; and that environmental standards must not become a barrier to Southern development.
• This inaugurated an intellectual tradition in Indian climate policy setting development against externally imposed environmental constraint.

Brundtland 1987 and the road to Rio

• The World Commission on Environment and Development, created in 1983, reported in 1987 as Our Common Future. Beyond the definition its contribution was procedural — it recommended the conference that became Rio, and linked environment to poverty, population, energy, industry and security in one frame.
• The Montreal Protocol on Substances that Deplete the Ozone Layer, agreed in the same year, remains the standard success case of environmental multilateralism.
  • Its parent instrument was the Vienna Convention for the Protection of the Ozone Layer (1985), a framework convention with no control measures — the model of “agree on the problem first”.
  • Montreal has achieved universal ratification, controls close to a hundred substances, and has been strengthened through the London, Copenhagen, Montreal, Beijing and Kigali adjustments and amendments.
  • The Multilateral Fund, created in 1990, finances developing-country compliance and is the working precedent for every later demand for climate finance.
  • The ozone layer is projected to recover to 1980 values around mid-century, the Antarctic hole last, and the Protocol has avoided greenhouse-gas emissions on a scale comparable to the climate treaties themselves.
  • The Kigali Amendment (2016), in force from 1 January 2019, phases down hydrofluorocarbons — potent greenhouse gases that were themselves ozone-friendly substitutes — on differentiated schedules, avoiding a projected 0.5°C of warming by 2100.
• Why ozone succeeded where climate has not is the single most instructive comparison in the field.
  • Substitutes existed and were commercialisable, so the affected industry became a stakeholder in regulation rather than its opponent.
  • The industry was concentrated in few firms in few countries, making monitoring feasible.
  • The causal chain was short and vivid — the Antarctic hole was a photograph — and the harm, skin cancer, was individually intelligible.
  • Costs were small relative to global output, and the differentiated timetable plus the Fund bought Southern participation.
  • Climate has none of these features: fossil energy underpins every economy, the emitting sectors are diffuse, harm is statistical and delayed, and cost is measured in points of GDP.

Rio 1992: the Earth Summit

• The UN Conference on Environment and Development at Rio de Janeiro in June 1992 produced the architecture within which environmental politics still operates.
  • The Rio Declaration (27 principles) restated Principle 21 as Principle 2 and added the operative norms of the field.
    • Principle 7 — common but differentiated responsibilities, the foundation of every subsequent equity argument.
    • Principle 15 — the precautionary approach: lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures where there are threats of serious or irreversible damage.
    • Principle 16 — the polluter-pays principle, that the polluter should in principle bear the cost of pollution.
    • Principle 10 — public participation, access to information and access to justice in environmental matters, later given treaty form regionally.
  • Agenda 21 was a 40-chapter non-binding action programme covering atmosphere, oceans, land, and the roles of women, indigenous peoples, workers and business, pioneering the “major groups” model of stakeholder participation; Local Agenda 21 produced thousands of municipal plans and is the ancestor of today’s city climate networks.
  • The Commission on Sustainable Development, created to monitor Agenda 21, lacked authority, degenerated into reporting, and was replaced in 2013 by the High-Level Political Forum.
  • The “Forest Principles” are the summit’s clearest failure: forested developing countries refused a binding convention, and there is still no global forest treaty.
• Three conventions emerged from or were opened for signature at Rio, and together they are the “Rio trio”.
  • The UN Framework Convention on Climate Change (UNFCCC), whose Article 2 sets the objective of stabilising greenhouse gas concentrations at a level preventing “dangerous anthropogenic interference with the climate system”, and whose Article 3 enshrines common but differentiated responsibilities and respective capabilities, precaution, and the right to sustainable development.
  • The Convention on Biological Diversity (CBD), with three objectives — conservation, sustainable use, and the fair and equitable sharing of benefits arising from genetic resources — and, crucially, an assertion of national sovereignty over genetic resources that displaced the older “common heritage” framing.
  • The UN Convention to Combat Desertification (UNCCD), negotiated after Rio at African insistence and adopted in 1994, the only Rio convention with a specifically Southern constituency at its origin.

Kyoto 1997 and the top-down architecture

• The Kyoto Protocol, adopted in 1997 and in force from 2005, was the first and so far only instrument imposing legally binding quantified emission targets.
  • Targets applied only to Annex I parties — industrialised countries and economies in transition — averaging a 5.2% reduction below 1990 levels over the first commitment period, 2008–2012.
  • The firewall between Annex I and non-Annex I parties was the institutional expression of CBDR, and its defence became the central objective of Indian and Chinese diplomacy for fifteen years.
• Three flexibility mechanisms allowed abatement to occur where it was cheapest.
  • International Emissions Trading between Annex I parties (Article 17) and Joint Implementation for projects between them (Article 6).
  • The Clean Development Mechanism (Article 12), generating certified emission reductions from projects in developing countries — the only mechanism giving the South a financial stake, and the one India embraced after initial scepticism, hosting one of the largest national portfolios.
• The Marrakesh Accords (2001) supplied the operating rulebook — accounting, land-use rules, the compliance committee — and were the price of keeping the Protocol alive after American withdrawal.
• Why Kyoto failed as a climate instrument, whatever its legal significance.
  • The United States never ratified, so the largest historical emitter carried no obligation; Canada withdrew in 2011 rather than face non-compliance findings.
  • Rapidly growing emitters had no targets, so global emissions rose sharply during the commitment period even where Annex I parties complied.
  • Carbon leakage — the migration of emitting production to unconstrained jurisdictions — undercut measured reductions.
  • The Doha Amendment (2012) established a second commitment period to 2020 covering a small fraction of global emissions; it took until 2020 to enter into force, by which time it was of historical interest only.

From Johannesburg to Copenhagen: the collapse of the top-down model

• The World Summit on Sustainable Development at Johannesburg (2002) produced an implementation plan and a turn towards public–private partnerships, and is generally judged the weakest of the mega-conferences.
• Rio+20 (2012) produced the outcome document “The Future We Want”, which declined to make UNEP a specialised agency but upgraded it to universal membership, replaced the Commission on Sustainable Development with the High-Level Political Forum, and launched the process that produced the Sustainable Development Goals.
  • The 2030 Agenda and its 17 SDGs, adopted in 2015, integrated environment into a universal development framework — SDG 13 on climate, 14 on life below water, 15 on life on land — but they are voluntary and indicator-tracked, reviewed through national presentations rather than compliance procedures.
• The Bali Road Map (COP 13, 2007) launched a two-track negotiation for a post-2012 regime and introduced nationally appropriate mitigation actions for developing countries — the moment India first accepted in principle that developing countries would mitigate voluntarily, in line with capability.
• Copenhagen (COP 15, 2009) failed to produce a treaty and, in failing, changed the architecture.
  • The Copenhagen Accord was negotiated by a small group of heads of government and merely “taken note of” by the plenary — a procedural scandal in a consensus body.
  • It recorded the 2°C goal and a pledge of US$100 billion a year by 2020, and decisively inverted the architecture from top-down differentiated targets to bottom-up pledge and review.
  • The failure discredited the idea of a binding universal instrument — one with assigned quantities was attainable.
• Cancun (COP 16, 2010) rescued the process, bringing the Copenhagen pledges inside the UN system and creating the Green Climate Fund, the Cancun Adaptation Framework, the Technology Mechanism and the beginnings of measurement, reporting and verification. India brokered the transparency compromise, a striking shift given that intrusive verification had been a sovereignty red line.
• Durban (COP 17, 2011) launched the Durban Platform, mandating a new instrument “applicable to all” by 2015 — with no reference to equity or CBDR, which is why Southern negotiators read it as the moment the firewall began to fall.
• Warsaw (COP 19, 2013) invited intended nationally determined contributions and created the Warsaw International Mechanism for Loss and Damage; Lima (COP 20, 2014) settled the INDC format.

Paris 2015: the bottom-up architecture

Feature	Kyoto Protocol (1997)	Paris Agreement (2015)
Architecture	Top-down: targets assigned by negotiation	Bottom-up: targets self-determined
Coverage	Annex I only — a firewall	Universal, with self-differentiation
Legal form of the target	Binding quantified obligation	Non-binding in content; binding in procedure
Differentiation	Categorical (Annex I / non-Annex I)	“In the light of different national circumstances”
Compliance	Enforcement branch with consequences	Facilitative, non-punitive, non-adversarial
Ambition-raising	Renegotiation of a new period	Five-yearly ratchet plus global stocktake
Temperature goal	None stated	Well below 2°C, pursuing efforts towards 1.5°C
Entry into force	2005, after eight years	2016, within a year — the design bought speed

• The Paris Agreement was adopted on 12 December 2015 and entered into force on 4 November 2016 — rapid ratification reflecting the deliberate lightness of its obligations.
• Its structural elements.
  • Article 2: hold warming to well below 2°C and pursue efforts to limit it to 1.5°C; increase adaptive capacity; align finance flows with low-emission, climate-resilient development.
  • Articles 3 and 4 — nationally determined contributions: parties must prepare, communicate and maintain successive NDCs and pursue domestic measures aimed at achieving them. The obligation is to have a contribution and pursue it, not to achieve it — conduct, not result.
  • Article 4.3 — the ratchet: each NDC must represent a progression and reflect highest possible ambition. There is no floor and no mechanism to reject an inadequate submission.
  • Article 6 — cooperative approaches: transfers between parties (6.2), the centralised Paris Agreement Crediting Mechanism (6.4) and non-market approaches (6.8); the rules took until 2024, chiefly over double counting and Kyoto-era credit carry-over.
  • Article 7 — the global goal on adaptation, deliberately qualitative, carrying the grievance that adaptation was mitigation’s junior partner.
  • Article 8 — loss and damage, admitted only with an accompanying decision stating that it provides no basis for liability or compensation — the price of American participation.
  • Article 9 — finance: developed countries obliged to provide and mobilise, others encouraged to do so voluntarily.
  • Article 13 — the enhanced transparency framework, with flexibility for low-capacity states: the regime’s real enforcement is reputational, through disclosure and peer review.
  • Article 14 — the global stocktake every five years from 2023, and Article 15 — a compliance committee that is facilitative, non-adversarial and non-punitive.
• Why the obligations are procedural rather than substantive is the crux of every assessment of Paris.
  • A state that submits an unambitious NDC and misses it has breached nothing; a state that fails to submit or report has.
  • The design was a deliberate trade of depth for participation: the Kyoto lesson was that a binding instrument major emitters refuse to join is worth less than a soft one everybody joins.
  • Defenders argue transparency plus the ratchet plus investor signalling does the work sanctions cannot; critics answer that in a decade aggregate NDCs have moved projected warming by less than a degree and never within reach of the goal.

The COPs since Paris

Conference	Year	What it settled
Marrakesh (COP 22)	2016	Implementation dialogue; the Marrakesh Partnership for Global Climate Action
Katowice (COP 24)	2018	The Paris Rulebook — common transparency, accounting and stocktake modalities; Article 6 deferred
Madrid (COP 25)	2019	Deadlock on carbon markets; widely regarded as the weakest post-Paris COP
Glasgow (COP 26)	2021	The Glasgow Climate Pact: 1.5°C reaffirmed as the effective goal, first-ever reference to fossil fuels, coal “phase-down” after a late Indian and Chinese amendment, doubling of adaptation finance by 2025, Article 6 rules largely closed
Sharm el-Sheikh (COP 27)	2022	Agreement in principle to establish a loss and damage fund — the single biggest Southern diplomatic win in the regime’s history
Dubai (COP 28)	2023	The first global stocktake, calling for “transitioning away from fossil fuels in energy systems”, tripling renewables and doubling efficiency by 2030; the loss and damage fund operationalised
Baku (COP 29)	2024	The New Collective Quantified Goal: at least US$300 billion a year by 2035 from developed countries, within a wider US$1.3 trillion aspiration; Article 6 fully operationalised
Belém (COP 30)	2025	The Global Mutirão decision; a call to triple adaptation finance by 2035; a just transition mechanism; no fossil-fuel roadmap in the text; 59 adaptation indicators adopted

• Glasgow’s coal amendment is the most cited procedural episode of the period: with the text agreed, India, supported by China, moved at the last moment to replace “phase-out” with “phase-down” of unabated coal, and the presidency accepted rather than lose the pact.
  • The Indian justification was consistency: singling out one fuel used overwhelmingly by developing economies while leaving oil and gas unnamed was selective differentiation.
  • The episode reads as obstruction in the North and as the exposure of a double standard in the South; both are defensible, which is why it remains the standard illustration of the divide.
• Baku’s finance outcome was objected to after the gavel. India’s delegate called the sum inadequate and the adoption stage-managed, with Nigeria and Bolivia joining; the presidency proceeded regardless. The US$1.3 trillion figure survives only as an aspiration to be pursued through a Baku-to-Belém roadmap.
• Belém exposed the limits of the consensus rule.
  • Over eighty countries pressed for a fossil-fuel transition roadmap; it did not enter the decision, and the presidency undertook to bring voluntary roadmaps forward outside the formal process.
  • The text acknowledged that overshoot of 1.5°C is now likely — the first such admission — and created three annual dialogues on unilateral trade measures, where carbon border adjustment now sits.

The regimes beyond climate

Regime	Instrument and date	Core mechanism	Standing problem
Ozone	Vienna 1985; Montreal 1987; Kigali 2016	Phase-out schedules, Multilateral Fund, trade restrictions with non-parties	Illegal production and HFC-23 venting; otherwise the success case
Biodiversity	CBD 1992; Cartagena 2000; Nagoya 2010; Kunming-Montreal 2022	National strategies, access and benefit-sharing, 23 targets including 30×30	No compliance mechanism; every previous target set was missed
Desertification	UNCCD 1994	National action programmes; land degradation neutrality	Chronically underfunded and marginal to the finance architecture
Hazardous waste	Basel 1989; Ban Amendment; plastics amendments 2019	Prior informed consent for transboundary movement	Waste “recycling” reclassification and illegal shipments
Chemicals	Rotterdam 1998; Stockholm POPs 2001; Minamata on mercury 2013	Listing, prior informed consent, elimination schedules	Slow listing; industry contestation of individual substances
Oceans	UNCLOS 1982; BBNJ 2023	Marine protected areas beyond national jurisdiction, environmental impact assessment, marine genetic resource benefit-sharing	Ratification breadth; overlap with existing sectoral bodies
Plastics	Mandate from the UN Environment Assembly, 2022	Intended full-life-cycle instrument	Negotiations deadlocked over production caps

• The Convention on Biological Diversity carries the field’s clearest record of failure and reform.
  • The Aichi Targets for 2011–2020 were adopted at Nagoya alongside the Nagoya Protocol on access and benefit-sharing; not one of the twenty was fully achieved.
  • The Kunming-Montreal Global Biodiversity Framework (2022) sets four goals and 23 targets for 2030, headed by Target 3 — protecting 30% of land and 30% of sea, “30×30”.
  • Progress is off track: roughly 17.6% of land and 8.4% of the ocean are covered by protected and conserved areas, so the marine estate would have to roughly triple in six years.
  • Its finance target — US$200 billion a year by 2030 and the repurposing of US$500 billion a year of harmful subsidies — suspended the Cali session in 2024 and was settled only at the resumed session in Rome in 2025, which agreed a permanent financial mechanism and the monitoring indicators.
  • The Cali Fund on digital sequence information obliges firms commercialising genetic sequence data to contribute, with a share earmarked for indigenous peoples — the first serious attempt at benefit-sharing where the resource has been dematerialised into a database.
• The BBNJ Agreement (2023) is the most significant new ocean instrument in four decades. Its sixtieth ratification was deposited in September 2025 and it entered into force on 17 January 2026, providing for high-seas marine protected areas, mandatory environmental impact assessment, benefit-sharing from marine genetic resources, and capacity building.
• The plastics treaty is the regime’s live failure. The 2022 mandate envisaged an instrument covering the full life cycle including production; a bloc of petrochemical producers insists on waste management only. The Geneva session of August 2025 collapsed without text, and the process has since been consumed by procedural reconstruction.

The politics of negotiation: blocs, conflicts and veto players

The three structural conflicts

• First: North against South over historical responsibility. In 1992 the answer was straightforward — a handful of industrialised countries accounted for most accumulated emissions, and the North conceded “historic responsibility”, accepting CBDR in Articles 3 and 4 of the UNFCCC alongside finance and technology commitments.
  • The conflict mutated rather than resolved: the United States insisted developing countries take on reduction measures, and their non-inclusion was the principal reason the Senate refused to ratify Kyoto.
  • The rise of the BASIC group — Brazil, South Africa, India and China — blurred the categorical distinction on which the original bargain rested.
• Second: fragmentation within the South. The early unity around resisting any growth-constraining obligation has broken up.
  • The driver is differential vulnerability: developing countries will suffer disproportionately, and adaptive capacity correlates with wealth.
  • AOSIS and the least developed countries demand that all countries reduce emissions, including large developing emitters; the BASIC states resist, fearing damage to their economies.
  • The “Global South” is not one negotiating actor: it coheres on finance and equity and splits on mitigation obligations, along the line dividing those exposed to sea-level rise from those exposed to an energy transition.
• Third: division within the North. The European Union acted for two decades as the pusher, imposing internal targets and using them as leverage; the United States with the JUSSCANNZ group, later the Umbrella Group, acted as the laggard, resisting binding obligations and pressing for market mechanisms and voluntary self-determined measures.
  • The Umbrella Group’s preference for a market-based, self-determined, voluntary architecture is precisely what Paris became — one way of reading who won the thirty-year argument.

The negotiating blocs

Bloc	Composition	Core demand
G77 and China	~134 developing states; the umbrella coalition	CBDR-RC, finance, technology transfer, no new obligations without means
BASIC	Brazil, South Africa, India, China	Protect development space; resist reclassification out of the developing category
AOSIS	~39 small island developing states and low-lying states	1.5°C, loss and damage, survival framed as a legal claim
LDCs	~45 least developed countries	Adaptation finance, grants not loans, simplified access
Africa Group	54 states	Adaptation, special needs and circumstances, desertification, energy access
Umbrella Group	US (until withdrawal), Japan, Canada, Australia, NZ, Norway, Ukraine and others	Universal applicability, market mechanisms, no top-down targets
European Union	27 member states negotiating as one	Binding ambition, ratchet mechanisms, carbon pricing
Arab Group / like-minded petrostates	Saudi Arabia, Kuwait and others	Response measures — compensation for lost fossil revenue; resist fuel-specific language
AILAC	Chile, Colombia, Costa Rica, Guatemala, Panama, Peru, Honduras	A progressive Latin American bridge between blocs
ALBA	Venezuela, Bolivia, Cuba, Nicaragua	Anti-capitalist climate justice; rights of nature; ecological debt
Like-Minded Developing Countries	India, China, Saudi Arabia, Malaysia, Bolivia, Egypt and others	Defend the firewall; resist reinterpretation of CBDR
High Ambition Coalition	Cross-cutting, EU with AOSIS and others	The coalition that carried Paris across the North–South line

• The consensus rule is the regime’s structural veto. The COP has operated since its first session without adopted rules of procedure, because of an unresolved objection over the voting rule in which Saudi Arabia’s position was decisive.
  • The consequence is decision by unanimity, occasionally overridden by a presidency declaring broad consensus over a few objections, producing outcomes at the lowest common denominator and a permanent incentive to hold the package hostage to one clause.
  • The countervailing argument: consensus is what makes universal participation possible: a majority-voting COP would produce stronger texts that the states with the emissions would leave.

Corporate power in environmental governance

• Neo-corporatism, in the sense given to it by Philippe Schmitter and Gerhard Lehmbruch, describes interest intermediation in which a few hierarchically ordered, non-competing peak associations hold a state-granted representational monopoly in exchange for constraints on their demands — the state governs with organised interests rather than merely being lobbied by them.
• In the globalised era that structure has been rescaled without being democratised. Business is incorporated into environmental policy-making, but the labour and civic associations of the classic corporatist bargain are weak or absent globally, so what emerges is representation without the balancing partner.
  • Institutionalised access: business and industry are a recognised constituency in the UNFCCC process, sitting on standard-setting bodies and formally consulted on rules governing their own conduct.
  • Numerical presence: over 1,600 delegates with fossil-fuel affiliations attended COP 30, roughly one participant in twenty-five, more than any national delegation but the host’s and more than the ten most climate-vulnerable countries combined.
  • Capture through expertise: the complexity of accounting rules, offset methodologies and product standards gives the regulated industry a structural advantage in writing the detail.
• The instruments of corporate influence are distinguishable and should not be run together.
  • Direct lobbying and campaign finance in the domestic arenas where ratification and implementation actually happen.
  • Manufactured scientific doubt — funding contrarian research and public-relations campaigns to prolong the appearance of controversy.
  • Greenwashing: net-zero pledges resting on unpurchased offsets, “carbon neutral” labelling, and voluntary standards designed to forestall binding regulation.
  • Regulatory arbitrage: relocating emitting production to weaker jurisdictions — the race to the bottom that competition for investment produces.
  • Investor-state dispute settlement, the sharpest instrument, because it converts environmental regulation into a compensable expropriation.
• The Energy Charter Treaty is the clearest case. Its investment protection chapter let energy companies sue states over climate policy: a German utility and its partner claimed billions over the Dutch coal phase-out, and a hydrocarbons company won an award against Italy’s offshore drilling ban.
  • Modernisation to carve out fossil fuels was judged insufficient, and the European Union and Euratom withdrew, with a substantial group of member states.
  • Its twenty-year sunset clause keeps existing investments protected long after withdrawal: treaty exit does not undo treaty exposure.
• The counter-argument deserves its place. Corporate capital is also the vehicle of the transition: the collapse in solar and battery costs came from firms competing for markets. The question is not whether business participates but on what terms and against what countervailing power.

The environmental regime incorporates business as a partner in rule-making while the labour and civic side of that bargain exists mainly at the national level — corporatism scaled up, with only one of its parties.

Climate justice and the North–South divide

Historical responsibility and the carbon budget

• The scientific basis of the equity argument is that warming tracks cumulative emissions, so the atmospheric space consumed historically is the relevant moral and legal quantity.
  • Of the emissions accumulated between 1850 and 2012, the United States contributed roughly 20%, the European Union 17% and China 12% — together about half the projected temperature increase to 2100 — while India contributed about 5%.
  • India’s cumulative share of carbon dioxide emissions since the industrial era remains under 4%, against a population of about a sixth of humanity.
• The carbon budget — emissions still consistent with a temperature goal — makes this operational: if the budget is nearly exhausted and was consumed by a minority, either late developers are foreclosed or the remainder must be allocated with reference to past use.
• The Southern argument in its strongest form is not that developing countries should do nothing.
  • Rich countries built their prosperity on unconstrained emissions and therefore owe the lead in cutting plus finance and technology.
  • Countries whose citizens lack reliable electricity cannot accept the same constraint as those whose citizens consume many times as much.
  • The Africa Group and small island states make the sharpest version: negligible contribution to the stock, existential exposure to the harm, which makes their claim one of justice, not charity.

Four ways to measure a country’s emissions

Metric	What it measures	Who it favours	Political use
Territorial (current flow)	Emissions produced inside borders this year	Small and rich states; penalises populous manufacturers	Standard UNFCCC reporting; the basis of “India is the third-largest emitter”
Per capita	Emissions divided by population	Populous developing states	India’s founding claim; ~2.2 tonnes per Indian against a world average roughly double that
Cumulative (historical)	Emissions accumulated since industrialisation	Late developers	The basis of historical responsibility and ecological debt
Consumption-based	Emissions embodied in what a country consumes, including imports	Manufacturing exporters	Exposes outsourced emissions; shows Northern reductions partly as relocation

• The per-capita claim’s Indian origin is a 1991 report, Global Warming in an Unequal World, which accused developed countries of “carbon colonialism” and argued that per-capita allocation should be the metric of responsibility. It became the bedrock of India’s position.
• Allocation proposals follow from the carbon-space frame.
  • Contraction and convergence proposes that global emissions contract to a safe level while national per-capita entitlements converge on equality by an agreed date, with trading permitted.
  • Greenhouse development rights weight obligations by capacity (income above a development threshold) and responsibility (cumulative emissions above it), producing obligations for wealthy individuals in poor countries too.
  • None was adopted. The regime moved to self-determined contributions, resolving the allocation question by refusing to ask it.

Mitigation, adaptation and the finance gap

	Mitigation	Adaptation
What it does	Reduces emissions at source	Reduces vulnerability to impacts already locked in
Who benefits	Everyone — a global public good	Locally, where the investment is made
Investment logic	Returns can be captured in markets — power, transport, industry	Returns are diffuse, avoided-loss and unpriced
Consequence	Attracts private capital at scale	Chronically underfunded; dominated by public and concessional money
Whose priority	The North’s, and large emitters’	The LDCs’, the Africa Group’s and small island states’

• Adaptation is underfunded structurally, not accidentally. Its benefits are localised avoided losses no investor can monetise, so it depends on exactly the public transfers that are hardest to negotiate.
  • Developing countries’ adaptation needs are assessed at over US$310 billion a year by 2035 against international public adaptation finance of roughly US$26 billion in 2023 — a gap of twelve to fourteen times current flows, with flows falling rather than rising.
  • The Glasgow pledge to double adaptation finance to around US$40 billion by 2025 was not met — the regime’s most concrete broken promise.
• Loss and damage is the third pillar, addressing harm neither prevented nor adapted to.
  • Conceded in principle at Sharm el-Sheikh in 2022, after three decades of Southern demands beginning with an AOSIS insurance proposal in 1991, and operationalised at Dubai in 2023 as the Fund for responding to Loss and Damage.
  • Pledges stand in the region of three-quarters of a billion dollars against needs in the hundreds of billions annually, and start-up disbursements have been correspondingly small. That gap between political significance and financial weight is the standing grievance.
• The US$100 billion pledge for 2020 was reported met only in 2022, on an accounting basis — loans at face value, re-labelled aid — that recipients dispute.
  • The New Collective Quantified Goal replaced it with at least US$300 billion a year by 2035, measured against needs an order of magnitude larger.

Technology transfer and intellectual property

• Developing countries have sought affordable access to green technology — solar, wind, storage, efficient industrial processes — since the UNFCCC’s Article 4.5 committed developed parties to promote and finance transfer.
• Intellectual property is the principal barrier in the Southern account. Patents held overwhelmingly in industrialised countries raise the cost of deployment, and licensing terms restrict local manufacture and adaptation.
  • Industrialised states hold the overwhelming majority of patents and transnational corporations most technology patents, so TRIPS-consistent transfer is transfer on the patent-holder’s terms.
  • India has proposed amending TRIPS to promote transfer of environmentally sound technology; the African Group has pressed for review of its treatment of indigenous knowledge.
  • The Northern reply: weak protection deters the research that produces the technology, and that the real barriers are absorptive capacity, finance and regulatory quality.
• The Technology Mechanism established at Cancun has proved an information and capacity institution rather than a transfer institution — the measure of the gap between demand and delivery.
• Biopiracy is the mirror-image dispute: patents granted on the properties of turmeric and neem, later revoked, show why the CBD’s benefit-sharing objective and the Nagoya Protocol matter to biodiversity-rich states, and why sovereignty over genetic resources displaced the common-heritage framing.

Environmental justice and the environmentalism of the poor

• Environmental justice began as an American claim about the racial and class distribution of pollution siting and generalises into the proposition that environmental burdens fall on those with least political power.
  • Its dimensions are distributive (who bears the harm), procedural (who is heard) and recognitional (whose knowledge counts).
  • Globally it appears as waste export, extractive frontiers, and the siting of polluting industry where regulation is weak and labour cheap.
• Indigenous peoples hold or manage a large share of remaining biodiversity while being excluded from decisions about it, which is why the Kunming-Montreal framework and the Cali Fund earmark benefit shares directly to them.
• Just transition carries this into policy: closing mines and thermal plants imposes concentrated regional and occupational losses, and a transition that does not compensate them generates the backlash that reverses it. A just transition mechanism was established at Belém in 2025.

Climate displacement and the legal gap

• Climate change is already a driver of displacement, mostly internal and disaster-related, running into tens of millions of new displacements a year, overwhelmingly within national borders.
• There is no legal category of “climate refugee.” The 1951 Refugee Convention requires a well-founded fear of persecution on five enumerated grounds, and environmental harm is not one of them.
  • Ioane Teitiota v New Zealand, decided by the UN Human Rights Committee in January 2020, rejected the Kiribati claim on the facts but held that climate effects may violate the right to life, so non-refoulement obligations can be triggered before the risk is imminent — an opening, not a remedy.
  • The Global Compact on Safe, Orderly and Regular Migration acknowledges environmental drivers but is non-binding; the Platform on Disaster Displacement does practical work without creating status.
  • Statehood is now a live question: if an island state’s territory becomes uninhabitable, the fate of its maritime zones, its nationals’ nationality and its legal personality is unresolved, and Pacific states press for continuity of statehood and fixed baselines.

Environmental degradation as a security question

From national to human security

• Traditional security takes the state as its referent object, external military attack as the threat, and defence, alliance and deterrence as the instruments.
• Comprehensive security widens the agenda to economic, environmental, societal and political sectors without changing the referent.
• Human security, formulated in the UNDP’s Human Development Report of 1994, shifts the referent object from the state to the individual and defines security as freedom from fear and freedom from want.
  • Its seven components are economic, food, health, environmental, personal, community and political security — environmental security is one of them, not an add-on.
  • The conceptual move is the change of referent, not the list.
• The environment appears twice in the frame: as its own component, and as a multiplier acting through the others, degrading food, health and economic security at once.

The mechanism, not the list

• Climate as a threat multiplier is the standard formulation, and its content is a causal chain rather than a category.
  • Warming reduces yields in already marginal agricultural regions.
  • Yield loss and production shocks raise prices, and price volatility rather than absolute global scarcity is what produces food insecurity.
  • Price shocks and livelihood collapse drive displacement, mostly internal.
  • Displacement and grievance produce political instability, which then degrades the capacity to respond to the next shock.
• Food insecurity arises from production shocks, price volatility, conflict and export restriction, not from a global shortage of calories.
  • The 2007–08 and 2022 price spikes showed how quickly export bans cascade once one large exporter moves.
  • The security consequence is documented: price shocks contributed to the unrest across North Africa and West Asia in 2010–11.
• Water stress operates mainly through internal displacement and local conflict rather than interstate war; the evidence supports this better than the “water wars” thesis.
  • Shared basins under stress — the Nile and the Grand Ethiopian Renaissance Dam, the Mekong, the Indus and the Brahmaputra — generate interstate friction, negotiation and occasionally coercion, but rarely armed conflict.
  • Technology reshapes the sovereignty question: the capacity to build storage and diversion infrastructure converts an upstream position into leverage, and the applicable law is thin. The UN Watercourses Convention of 1997 took until 2014 to enter into force, has few parties and no major Asian riparian among them; China voted against it.
  • The Indus Waters Treaty shows both the durability and the fragility of such arrangements: it survived three wars before India held it in abeyance in 2025 after a terrorist attack, the arbitral body constituted under it asserting that the treaty remains in force and India rejecting its competence.
• Sea-level rise threatens the territorial existence of small island states, which makes their security claim literal rather than metaphorical.
• Health security was demonstrated by the pandemic: a pathogen did more damage to economies and mobility than any conventional threat of the period.
• The common features of these non-traditional threats are what make an analysis rather than a list: they are transnational, so no state can address them alone; non-military in origin, so defence budgets do not answer them; asymmetric, falling hardest on the poorest; and interlinked, each amplifying the next.

The securitisation debate

• The Copenhagen School — Barry Buzan and Ole Wæver — treats security as a speech act: an issue becomes a security issue when an actor successfully presents it as an existential threat requiring emergency measures, and the audience accepts the claim.
• The case for securitising is that it raises priority, unlocks resources ordinary policy channels cannot command, and accurately describes threats that are existential for some states.
• The case against is stronger than it first appears.
  • Emergency framing licenses emergency measures, and a militarised response to a developmental problem can make it worse — border hardening against climate migrants rather than adaptation finance.
  • It shifts the issue out of democratic deliberation into executive and security bureaucracies.
  • If everything is security the concept loses analytical purchase; the reply is that the narrow definition excluded the causes of most preventable deaths.
  • Desecuritisation — returning an issue to normal politics — is often preferable.
• The Security Council has never adopted a thematic climate resolution; a 2021 draft was vetoed on the argument that climate belongs in the UNFCCC where all states negotiate, not in a body where five hold vetoes — itself a sovereignty argument rather than mere obstruction.

Contested strategies and technologies

Geoengineering

• Geoengineering covers deliberate large-scale intervention in the Earth system, in two families with different risk profiles.
  • Carbon dioxide removal — afforestation, soil carbon, enhanced weathering, bioenergy with carbon capture, direct air capture — addresses the cause, is slow, and is already embedded in most modelled pathways to 1.5°C, itself a controversial dependence on technology not yet deployed at scale.
  • Solar radiation management, chiefly stratospheric aerosol injection, addresses only the symptom, is cheap enough for a single actor to attempt unilaterally, and does nothing about ocean acidification.
• The political objections to solar radiation management are the serious ones.
  • Termination shock: stopping abruptly after prolonged deployment produces very rapid warming.
  • Distributional effects: changes to monsoon and regional precipitation create winners and losers with no mechanism to adjudicate between them.
  • Moral hazard: a cheap thermostat weakens the case for costly abatement.
  • Governance vacuum: no regime has competence, and a proposal at the UN Environment Assembly for an expert review was withdrawn, leaving research governance to voluntary norms.
• Marine geoengineering is partially regulated through amendments to the London Protocol on dumping — the closest thing to a precedent.

Nuclear energy

• Nuclear power is low-carbon and dispatchable, which makes it attractive for the hard-to-decarbonise base of an electricity system.
• The objections are safety, waste and cost. Long-lived waste has no operating deep geological repository in most countries; capital costs and overruns have made large reactors uncompetitive in liberalised markets; and accidents, though rare, are politically decisive.
• The international divergence is durable. China, India, Russia, France and the United Kingdom are building or planning capacity, with small modular reactors the current hope for cost control; Germany completed its phase-out, and others have followed.
• The proliferation linkage makes this an IR question rather than an energy-policy question: the fuel cycle is dual-use, enrichment and reprocessing are the pathway to weapons material, and safeguards are the price of civil cooperation.
• India’s position is distinctive: a three-stage programme built around thorium, civil nuclear commerce opened by the 2008 exemption despite non-adherence to the Non-Proliferation Treaty, and a liability law that has deterred foreign vendors.

Carbon markets and offsets

• Carbon pricing is the economists’ first-best instrument, as a tax or a cap-and-trade system, now covering a substantial minority of global emissions across dozens of jurisdictions.
• Offsetting — paying for a reduction elsewhere instead of reducing at source — is the contested part.
  • Additionality: a credit is real only if the reduction would not have happened anyway, a counterfactual that cannot be observed.
  • Permanence: forest carbon can burn. Leakage: protection here can displace logging there.
  • Investigations into voluntary forest credits have found large proportions of doubtful value, which is why Article 6.4’s stricter additionality tests matter.
• Distributive objections come from the South too: offsets let the North buy the cheapest abatement in the South while occupying land and forest — carbon colonialism in a second sense.

The collision between trade and environment

• The tension is structural: trade law disciplines measures that discriminate between “like products”, while environmental policy frequently needs to discriminate precisely by how a product was made.
• WTO jurisprudence has moved, but only so far.
  • US–Shrimp (Shrimp-Turtle) established that a measure protecting an exhaustible natural resource beyond the regulating state’s jurisdiction can fall within GATT Article XX(g); the American measure failed only on the chapeau, for arbitrary discrimination in its application. It is the leading authority that environmental measures are not inherently WTO-illegal.
  • US–Gasoline and EC–Asbestos trace the same line: the objective may be legitimate, the application must not discriminate.
  • India — Solar Cells (DS456) cuts the other way: the domestic content requirements in India’s solar mission violated the TRIMs Agreement and GATT Article III:4, and India’s Article XX(j) and XX(d) defences failed in 2016 — green industrial policy is actionable when a developing country does it.
• The Carbon Border Adjustment Mechanism is now the central trade-and-climate dispute.
  • The European Union’s CBAM applies a charge at the border reflecting the embedded carbon of imports in iron and steel, cement, aluminium, fertilisers, electricity and hydrogen, with a transitional reporting-only phase from October 2023 and the definitive regime from 1 January 2026.
  • The EU’s justification is the prevention of carbon leakage: without it, domestic carbon pricing simply exports emissions and industry.
  • The developing-world objection has four distinct limbs.
    • It is unilateral, applying an EU-determined carbon price to producers who never agreed to it, substituting a trade instrument for a negotiated one.
    • It ignores CBDR, applying an identical standard to producers at different levels of development.
    • Its revenue accrues to the EU budget rather than being recycled to affected exporters as transition finance.
    • Its compliance burden — installation-level emissions accounting — falls hardest on small producers with the weakest data systems.
  • Indian estimates put the effective additional burden on covered exports at a substantial share of their value, concentrated in steel and aluminium.
  • India treats carbon border measures as unilateral trade-restrictive climate measures, presses the issue in the UNFCCC — where three annual dialogues on such measures were established at Belém — and is building a domestic carbon price so that the value is captured at home rather than at the European border.
• Deforestation regulation repeats the structure elsewhere: the EU’s due-diligence rule for palm oil, soy, cocoa, coffee, cattle, rubber and timber has been postponed twice, to the end of 2026, and producer states call it a green trade barrier imposed without their consent.
• Green subsidies and critical minerals complete the picture.
  • The US Inflation Reduction Act tied large clean-energy subsidies to domestic content conditions, provoking objections from allies and developing countries and legitimising green industrial policy — before much of it was scaled back in 2025.
  • Critical minerals reproduce classic resource politics inside the transition: extraction concentrated in a few developing countries, processing overwhelmingly in China, export controls used as leverage. Extraction costs fall where the minerals are; value added accrues where they are processed.

Climate change in the courts

• Climate litigation has become a distinct front, with thousands of cases filed worldwide, roughly a quarter of them outside the United States, and a marked shift from tort claims against companies toward constitutional and human-rights claims against governments.
• The domestic wave.
  • Urgenda v the Netherlands (Dutch Supreme Court, 2019) upheld an order to cut emissions at least 25% below 1990 levels by end-2020, on the duty of care and Articles 2 and 8 of the European Convention on Human Rights — a court setting a numerical minimum for climate policy.
  • Neubauer v Germany (Federal Constitutional Court, 2021) held the Federal Climate Protection Act partly unconstitutional for deferring reduction beyond 2030 and infringing the freedoms of the young — the doctrine of intertemporal protection of freedom.
• The regional and international turn.
  • Verein KlimaSeniorinnen Schweiz v Switzerland (European Court of Human Rights, Grand Chamber, 9 April 2024) found a violation of Article 8 where a state lacks an adequate regulatory framework including a quantified carbon budget, and of Article 6(1) on access to court. Its companion cases fell on admissibility: associations, not individuals, are the viable applicants.
  • The International Tribunal for the Law of the Sea, advising the Commission of Small Island States on 21 May 2024, held unanimously that greenhouse gas emissions constitute marine pollution under the law of the sea, that the due diligence standard is stringent, and that compliance with the Paris Agreement does not by itself discharge the obligation.
  • The International Court of Justice delivered its advisory opinion on 23 July 2025, on a request initiated by Vanuatu and carried through the General Assembly by a coalition of small island states.
    • Climate obligations arise not only from the climate treaties but from customary international law and human rights law, so a state outside the Paris Agreement is not thereby outside the duty.
    • The 1.5°C figure is treated as the agreed primary temperature goal rather than as an aspiration.
    • Failure to act — including through fossil fuel production, exploration licences and subsidies — may constitute an internationally wrongful act, carrying consequences of cessation and reparation.
    • The opinion is not binding, but it supplies the legal premises for a generation of litigation, which is why it matters more than its formal status suggests.
• Why this matters. Adjudication supplies what the Paris architecture lacks — an enforcement pathway — without renegotiating anything. The objection is one of legitimacy and capacity: courts are asked to set economy-wide policy on evidence they are not designed to weigh.

India in global environmental politics

The intellectual foundations

• India’s climate diplomacy rests on a tradition inaugurated at Stockholm in 1972, when the Prime Minister set socio-economic development against externally imposed environmental constraint and attributed global environmental problems to Northern industrialisation.
• The 1991 “carbon colonialism” argument supplied its analytical form ahead of Rio: developed countries bear the bulk of responsibility because of historical emissions, and per-capita allocation is the right metric for dividing the remaining burden.
• The arithmetic is why the position has survived thirty years of pressure.
  • India’s cumulative contribution from 1850 to 2012 was about 5%, against roughly 20% for the United States and 17% for the European Union.
  • Per-capita emissions of about 2.2 tonnes are well under half the world average; per-capita electricity consumption remains far below the OECD level.
  • The counter-fact is equally real: on current flows India is the third-largest emitter, at roughly 8% of annual global carbon dioxide emissions, and rising.
• Navroz Dubash captures the position: India is at once a large current emitter and a state with small historical responsibility, highly vulnerable to a problem it did little to cause — a unique and structurally awkward role.
• Dubash’s typology of Indian climate narratives organises the domestic argument.
  • Growth-first stonewallers: poverty and development come first; equity is both principle and a device to keep obligations out.
  • Progressive realists: the negotiations are unfair but contain opportunities; climate is a real threat to India; domestic action has co-benefits.
  • Progressive internationalists: shape the process through engagement; climate will hurt the poor most; link domestic action to the global regime.
  • The 1990s correspond to the first, Copenhagen to the second, Paris to the third.

From defending the firewall to building the rules

• Rio, 1992: India identified with the G77, urging developed-country action while accepting only voluntary commitments conditional on finance and technology; the insertion of CBDR and respective capabilities into Article 3 is a victory Indian negotiators claim substantial credit for.
• Kyoto, 1997: the firewall exempting non-Annex I parties was the objective and it was achieved. India’s initial scepticism of the Clean Development Mechanism was reversed in 2002, after which Indian firms became among its largest users.
• Bali, 2007: India accepted, to general surprise, that developing countries would mitigate voluntarily, in line with capability.
• Domestically, 2008: the National Action Plan on Climate Change created eight missions — solar, energy efficiency, sustainable habitat, water, the Himalayan ecosystem, Green India, sustainable agriculture and strategic knowledge — with state action plans beneath them. Its significance was diplomatic as much as domestic: it let India point to action while resisting obligation.
• Copenhagen, 2009: India announced, with the BASIC countries, a voluntary cut in the emissions intensity of GDP of 20–25% against 2005 levels by 2020, and undertook never to exceed developed countries’ per-capita emissions — departures for a state that had refused voluntary commitments at Kyoto.
  • Three foreign-policy motives shaped the shift: the ambition for a permanent Security Council seat, which needed G77 goodwill that intransigence was eroding; criticism from climate-vulnerable G77 members such as the Maldives and Bangladesh; and the deepening partnership with the United States after the civil nuclear agreement and the 2008 exemption for nuclear commerce.
• Cancun, 2010: India brokered the transparency compromise, having treated international verification as a sovereignty red line.
• Durban, 2011: India resisted, and lost, the argument over an instrument “applicable to all” with no reference to CBDR.
• Paris, 2015: India accepted the 1.5°C aspiration despite the risk that a tighter goal forecloses carbon space for late industrialisers, and launched the International Solar Alliance on the margins.
  • Its 2015 NDC pledged 40% of installed electric capacity from non-fossil sources by 2030, a 33–35% cut in emissions intensity against 2005 levels, and an additional carbon sink of 2.5–3 billion tonnes of carbon dioxide equivalent.
  • Domestic critics read participation as a break with the traditional logic and the Paris equity language as reduced to “sweet nothings”; the alternative reading is that India moved from rule-taker to rule-shaper.

The constitutional and judicial layer

• Article 48A directs the state to protect and improve the environment and safeguard forests and wildlife; Article 51A(g) makes it a fundamental duty of every citizen to do the same. Both were inserted by the 42nd Amendment.
• Article 21 has carried the operative right. In Subhash Kumar v State of Bihar the Supreme Court held that the right to life includes the right to enjoyment of pollution-free water and air.
• The M.C. Mehta line of litigation built the working doctrine.
  • Absolute liability for hazardous enterprise in the Oleum gas leak case, displacing the English rule of strict liability with its exceptions.
  • The polluter-pays and precautionary principles, and the public trust doctrine, read into domestic law as part of the law of the land.
  • Continuing mandamus as the procedural technique — the Ganga and Taj Trapezium matters — by which the Court supervises executive action over years.
• The National Green Tribunal, created in 2010, gave India one of the world’s few dedicated environmental courts, with expert members alongside judicial ones; its record mixes significant enforcement with criticism over the erosion of its powers.
• M.K. Ranjitsinh v Union of India (2024) is the constitutional turning point. Hearing a matter on transmission lines through Great Indian Bustard habitat, the Supreme Court recognised a right against the adverse effects of climate change under Articles 14 and 21 — the other side of the coin of the right to a clean environment.
  • It simultaneously relaxed the prohibition on overhead lines in favour of solar deployment — which is why it is criticised as recognising a climate right while subordinating a biodiversity claim, and as declaring a right without a remedy.

Contemporary Indian climate policy

• The Panchamrit commitments made at Glasgow in 2021 set five goals: 500 GW of non-fossil capacity by 2030, half of energy needs from renewables, a one-billion-tonne cut in projected emissions, a 45% cut in emissions intensity against 2005 levels, and net zero by 2070.
• Progress on capacity has run ahead of the pledge. Non-fossil sources crossed 50% of installed electricity capacity in 2025, five years early, reaching roughly 283 GW by March 2026 — about 150 GW solar and 56 GW wind — after the largest annual addition on record.
  • The qualification that matters: capacity is not generation. Coal still supplies most electricity actually generated, and thermal capacity continues to expand for firm supply, which is why the emissions curve has not turned.
• The updated NDC for 2031–2035, approved in 2026, commits India to reduce the emissions intensity of GDP by 47% by 2035 against 2005 levels, to reach 60% of cumulative installed electric capacity from non-fossil sources by 2035, and to create an additional carbon sink of 3.5 to 4 billion tonnes of carbon dioxide equivalent.
• Domestic instruments have multiplied.
  • The Carbon Credit Trading Scheme, notified under the amended Energy Conservation Act, turns the earlier energy-efficiency trading scheme into an emissions-intensity compliance market for energy-intensive sectors, with an offset mechanism alongside.
  • The Green Credit Programme creates tradable credits for voluntary environmental action beginning with plantation on degraded land, criticised for treating plantation as equivalent to forest.
  • Mission LiFE — Lifestyle for Environment reframes mitigation around individual and community behaviour and was carried into the G20 New Delhi Leaders’ Declaration; the critique is that it shifts attention from structural to behavioural change.
  • The National Green Hydrogen Mission, the PM Surya Ghar rooftop solar scheme and production-linked incentives for solar manufacturing form the industrial-policy limb.
• Institution-building abroad is the distinctive feature of Indian environmental diplomacy — creating organisations rather than only negotiating inside them.
  • The International Solar Alliance, launched with France at Paris and headquartered in India, has over a hundred signatories and more than ninety full members.
  • The Coalition for Disaster Resilient Infrastructure (2019) has passed fifty member countries; the Global Biofuels Alliance, launched at the New Delhi G20 in 2023, has more than thirty.
  • The Big Cat Alliance and the Global Green Credit Initiative extend the model into conservation and land restoration.
• India’s standing positions are consistent across these institutions.
  • Coal: phase-down, not phase-out, of unabated coal — fuel-specific targeting is selective and energy access is a development necessity.
  • Finance: the NCQG is inadequate, and finance must be grant-based and public rather than loans counted at face value.
  • CBAM and unilateral measures: trade protection in environmental form, incompatible with CBDR, to be resisted through the UNFCCC and trade negotiation.
  • Equity: the per-capita and cumulative frames remain the reference, even as absolute emissions make the argument harder to sustain rhetorically.

China and India compared

Dimension	China	India
Share of global CO₂ emissions	Roughly 30% — the largest emitter by a wide margin	Roughly 8% — third largest
Per-capita emissions	Above the world average, now around European levels	About 2.2 tonnes, well below the world average
Cumulative share since 1850	Around 12% and rising fast	Around 4%
Net-zero date	2060	2070
2035 pledge	First-ever absolute cut: 7–10% below peak	47% intensity cut against 2005; 60% non-fossil capacity
Peaking commitment	Committed to peak before 2030	No peaking year declared
Position on differentiation	Insists on developing-country status while acting as a great power	Insists on CBDR with a materially stronger equity case
Clean-tech role	The manufacturing hegemon — dominates solar, batteries, processed critical minerals	A deploying market building manufacturing capacity behind incentives
Institutional strategy	Leverage inside existing bodies; South-South cooperation and Belt and Road energy finance	Creating new institutions — solar alliance, disaster resilience coalition, biofuels alliance
Negotiating style	Bilateral great-power management, notably with the United States	Coalition-building through the G77, BASIC and the like-minded group
Coal	Largest producer and consumer; continued approvals alongside record renewables	Expanding thermal capacity for firm supply; defends phase-down language
Convergence	Both defended the firewall, both co-authored the Glasgow coal amendment, both refuse absolute caps imposed externally

• The analytical point is that the two occupy the same bloc and different positions. China’s equity claim erodes as its per-capita emissions pass European levels and its cumulative share climbs; India’s remains intact. That divergence is the likeliest future fault line inside the developing-country coalition.
• The clean-technology asymmetry cuts the other way. China’s manufacturing dominance gives it leverage over the cost and pace of everyone else’s transition, India’s included — which is why India’s solar manufacturing incentives are climate, industrial and strategic policy at once.

India’s climate position is unusual in resting on an equity claim that the arithmetic still supports — a low per-capita, low-cumulative profile attached to the world’s third-largest emissions flow.

Where the regime stands now

• Warming has reached the Paris lower goal on a single-year basis. The three-year mean for 2023–2025 was about 1.48°C above the 1850–1900 baseline, with 2025 at roughly 1.44°C. The long-term average that defines the Paris goal has not been breached, but the margin has gone.
• The gap between pledges and the goal has narrowed only marginally. Full implementation of current NDCs points to roughly 2.3–2.5°C by 2100 and current policies to as much as 2.8°C; global greenhouse gas emissions reached 57.7 gigatonnes of carbon dioxide equivalent in 2024, still rising.
• The first Earth-system tipping point is assessed as crossed. Warm-water coral reefs have entered widespread dieback, with the global bleaching event beginning in 2023 affecting an estimated 84% of reef area, and scientists now describe this as the first tipping point passed rather than approached.
• The United States has left the Paris Agreement for the second time, with withdrawal taking effect on 27 January 2026, accompanied by the rollback of clean-energy tax provisions, the withdrawal of climate finance, and obstruction in adjacent forums including shipping decarbonisation.
  • The 2017 episode is the guide to reading this one. No other party followed the first withdrawal, subnational and corporate coalitions maintained a share of American abatement, and the next administration rejoined: the regime survived because its architecture is voluntary and not structurally dependent on any single party.
  • What is different now is that withdrawal coincides with fiscal retrenchment in European aid budgets, a harder trade environment and a Chinese pledge analysts judge unambitious, so the loss is not offset by acceleration elsewhere.
  • The counter-effect is that American absence removes the party most resistant to loss-and-damage liability language and strengthens the EU–China–Brazil axis — a change in political geometry, not only a subtraction.
• COP 31 will be held at Antalya under a Turkish presidency, with Australia leading the negotiations under an unusual shared arrangement agreed at Belém after a contested bid — the first time the host and the president of the negotiations have been split in this way.
• Finance remains the unresolved core. The Baku goal of US$300 billion a year by 2035 stands against assessed adaptation needs alone of over US$310 billion a year, the loss and damage fund is capitalised in the hundreds of millions against needs in the hundreds of billions, and the Baku-to-Belém roadmap to US$1.3 trillion is an aspiration, not an obligation.
• New instruments outside the climate track are where the movement is.
  • The BBNJ agreement entered into force in January 2026, its first Conference of the Parties due within a year.
  • The seventh UN Environment Assembly adopted eleven resolutions in December 2025 on coral reefs, minerals and metals, glaciers, wildfires and artificial intelligence.
  • The Tropical Forest Forever Facility launched at Belém with over US$5.5 billion announced against a US$125 billion target, paying per hectare of standing forest with at least a fifth directed to indigenous peoples.
• The plastics negotiation remains deadlocked, having produced no text in 2025 and spent the following period reconstituting its chairmanship — the clearest current demonstration of what consensus does when a producer bloc’s core interest is at stake.
• The scientific process is between cycles. The seventh IPCC assessment expects working group reports from 2028 and a synthesis in 2029, with a special report on climate change and cities in 2027, and an unresolved argument about accelerating it to inform the second global stocktake in 2028.

Critiques and unresolved problems

• Implementation, not agreement, is the binding constraint. The regime has produced a framework convention, a protocol, an agreement, a rulebook and hundreds of decisions; global emissions have risen throughout.
• The sovereignty problem is unresolved and probably unresolvable within the present system: no authority above the state can set or enforce a national emissions limit, and the states with the emissions are least willing to accept one.
• Differentiation has no agreed formula. CBDR was clear in 1992 and is contested now; “in the light of different national circumstances” lets every party differentiate itself.
• Finance pledges have a record of being late, smaller than announced and delivered as loans, which corrodes the trust every future bargain depends on — the South’s willingness to accept obligations has always been conditional on means of implementation.
• The consensus rule guarantees the lowest common denominator and hands a veto to the parties with least interest in an outcome, while majority voting would buy stronger text at the cost of universality.
• Adaptation and loss and damage remain structurally subordinate to mitigation, because they generate no returns private capital can capture.
• Monitoring is improving but enforcement is reputational, which works on states that care about reputation and not on those that do not.
• Short political horizons face long physical ones: abatement costs are immediate and concentrated, benefits distant and diffuse, electoral cycles shorter than climate response times.
• Environmentalism can itself become a barrier to development when rich-country standards are applied at the border without transition finance — the substance of the Southern objection to carbon border measures and deforestation rules.
• The counter-critique is worth stating. The regime has delivered a universal participation norm, an information infrastructure that makes evasion visible, a price signal that cut renewable costs by an order of magnitude, and a legal vocabulary now enforced in courts the drafters never anticipated — and projected warming is materially lower than a decade ago.

Conclusion

The environment shows the structure of contemporary global concerns in its clearest form: costs that are global, authority that is national, and worst effects falling on those least responsible. Thirty years of negotiation have produced a regime that is universal, transparent and voluntary, and the trade of enforceability for participation was deliberate. That trade is now being tested from outside — by courts converting soft treaty language into hard obligation, by trade instruments imposing standards the negotiations could not agree, and by a physical system crossing thresholds while the parties argue about who pays.
