01
What is Climate Ethics?
The moral philosophy behind environmental responsibility
Climate ethics is the branch of applied ethics that examines the moral dimensions of climate change — who is responsible, who bears the burden of consequences, and how obligations should be distributed across nations, generations, and species. It bridges environmental philosophy, political theory, and international law.
The discipline gained academic and policy prominence after the 1992 Rio Earth Summit and has since shaped the foundational principles of every major climate agreement, including the Kyoto Protocol (1997) and the Paris Agreement (2015).
Core Ethical Premise
Climate change is not merely a scientific or economic challenge — it is fundamentally a problem of
justice
. Those who have contributed least to greenhouse gas emissions historically (developing nations, indigenous communities, future generations) bear the heaviest burden of its consequences.
🌐 Distributive Justice
How should the costs and benefits of climate action be fairly distributed among nations and peoples? The Global South bears disproportionate risk despite minimal historical emissions.
⏳ Intergenerational Equity
Present generations have a moral duty to preserve a habitable planet for future generations. The Brundtland Commission (1987) enshrined this in the definition of sustainable development.
🏭 Historical Responsibility
Industrialised nations built wealth through centuries of carbon emissions. The “polluter pays” principle demands proportional responsibility and financing from high-emitting nations.
⚖ Common But Differentiated
All states share responsibility for climate protection, but their obligations differ based on capability and historical contribution — enshrined in UNFCCC Article 3 as CBDR-RC.

03
CBDR-RC: The Ethical Core of Climate Law
Common But Differentiated Responsibilities and Respective Capabilities
CBDR-RC
is the foundational ethical-legal principle of international climate governance, first articulated in the Rio Declaration (1992) and embedded in the UNFCCC. It acknowledges that while all nations share the planet and the obligation to protect it, their responsibilities are
not
identical.
The principle rests on two axes:
historical contribution
to cumulative emissions (which favours holding developed nations to higher standards) and
current capacity
to act (financial and technological ability). India has consistently championed CBDR-RC in global negotiations, arguing that per-capita equity must underpin any fair climate deal.
India’s Position — Key Argument
India’s per-capita cumulative CO₂ emissions are a
fraction
of the USA or EU. India represents 17% of the world’s population but accounts for less than 5% of cumulative historical emissions. CBDR-RC justifies India’s right to development while taking climate action proportionate to its capacity.
⚡ North-South Climate Tensions — Ethical Flashpoints
Loss & Damage:
Who compensates island nations for sea-level rise? COP27 created a Loss and Damage Fund — a breakthrough long demanded by the Global South.
Climate Finance:
Developed nations pledged $100 billion/year by 2020 — a promise unfulfilled until 2023, prompting accusations of ethical default.
Technology Transfer:
Green technology developed with public funding in the North remains locked behind IP barriers, hindering Southern transitions.
Carbon Colonialism:
Critics argue Western carbon offset projects in Africa and Asia displace communities under the guise of conservation.
Just Transition:
Fossil fuel workers and coal-dependent nations (like India’s Jharkhand) need economic alternatives before coal is abandoned.
04
Carbon Credits: Mechanism & Architecture
How market-based emission reduction is structured
A
carbon credit
(also called a carbon offset) is a tradeable certificate representing the reduction or removal of one metric tonne of CO₂ equivalent (CO₂e) from the atmosphere. These credits emerge from projects that either prevent emissions (renewable energy, efficient cookstoves) or sequester carbon (afforestation, blue carbon ecosystems).
The carbon credit system is built on the economic insight that emission reductions are cheaper in some locations than others. Rather than each entity reducing emissions at high cost locally, they can purchase credits from where reductions are cost-effective — achieving the same atmospheric outcome at lower economic cost.
🏭
Cap-and-Trade
Regulators set a cap on total emissions. Entities receive or buy permits. Those that emit less can sell surplus permits. Cap decreases over time, ratcheting down total emissions.
🌳
Carbon Offset Projects
Projects that reduce or remove emissions generate credits — solar farms, avoided deforestation (REDD+), methane capture, ocean kelp restoration. Credits sold to entities to “offset” their footprint.
📊
Voluntary Markets
Companies buy credits voluntarily for ESG goals and net-zero commitments. Major registries: Verra (VCS), Gold Standard, American Carbon Registry. ~$2 billion market in 2023.
🌐
Compliance Markets
Legally mandated markets — EU Emissions Trading System (ETS) is the world’s largest. Covers ~40% of EU greenhouse gas emissions, generating billions in climate revenue annually.
05
Evolution of Carbon Markets: A Timeline
From Kyoto to the Carbon Credit Corporation Act 2023
1992
UNFCCC Established
United Nations Framework Convention on Climate Change sets the foundation for international climate cooperation at the Rio Earth Summit.
1997
Kyoto Protocol — CDM Born
Clean Development Mechanism (CDM) under Kyoto allows developed nations to earn emission credits by funding projects in developing countries. India became a major CDM host.
2005
EU ETS Launched
European Union Emissions Trading System becomes the world’s first and largest carbon market. Sets global benchmark for cap-and-trade architecture.
2015
Paris Agreement — Article 6
Paris Agreement’s Article 6 creates a new framework for international carbon trading, replacing CDM. Article 6.2 (cooperative approaches) and 6.4 (new UN mechanism) establish post-Kyoto market rules.
2021
COP26 Glasgow — Article 6 Finalised
Rules for Article 6 carbon markets finalised after years of deadlock. “Corresponding adjustments” ensure credits are not double-counted by both seller and buyer countries.
2022
COP27 — Loss & Damage Fund
Historic agreement to create a Loss and Damage fund for climate-vulnerable nations — a major ethical victory for the Global South that also reshapes how climate finance flows.
2023
India Launches Carbon Credit Programme
India amends the Energy Conservation Act 2001 to create a domestic Carbon Credit Trading Scheme (CCTS). Bureau of Energy Efficiency designated as nodal body for India’s first domestic carbon market.
06
India & Carbon Credits
From CDM beneficiary to domestic market architect
India has had a complex but increasingly central relationship with carbon markets. As a major CDM host under Kyoto, India registered hundreds of projects generating millions of Certified Emission Reductions (CERs), particularly in renewable energy, industrial efficiency, and waste management sectors.
In the post-Paris era, India submitted Nationally Determined Contributions (NDCs) committing to reduce emissions intensity of GDP by 45% by 2030 from 2005 levels, and achieve 50% of cumulative electric power from non-fossil sources by 2030. Carbon markets are seen as a key instrument to finance this transition without sacrificing development goals.

Ethical Critiques of Carbon Markets
The moral tensions beneath market mechanisms
Carbon credits, while theoretically efficient, have attracted serious ethical criticism from environmental philosophers, climate justice activists, and scientists. These critiques go to the heart of whether markets can resolve what is fundamentally a moral and political problem.
🚨
Greenwashing Risk
Companies that buy carbon offsets may claim “net-zero” without reducing actual emissions. Investigations in 2023 revealed that several leading carbon projects (VERRA-certified rainforest offsets) overstated their impact by up to 94%.
🏘
Carbon Colonialism
Conservation projects in Africa, Asia and Latin America for carbon credits have displaced indigenous communities from ancestral lands — replicating colonial patterns under the guise of climate action.
💸
Commodifying Nature
Assigning a market price to carbon turns ecological systems into financial instruments. Critics argue this fundamentally misunderstands the moral value of nature and ecosystems.
⏩
Delaying Real Action
The availability of cheap offsets may reduce incentives for structural decarbonisation — the “licence to pollute” critique. Without a rising carbon price, offsets become a permanent escape valve rather than a bridge.
📉
Additionality Problem
Credits should only exist for reductions that are “additional” — would not have happened anyway. In practice, many offset projects are not truly additional, meaning no real atmospheric benefit occurs.
🔄
Permanence Issue
Forest-based credits assume trees will stand forever, but wildfires, disease, and policy changes can reverse sequestration rapidly. Australia’s carbon credit scheme faced major criticism on this ground.
08
Article 6 of the Paris Agreement
The new architecture of international carbon trading
Article 6 of the Paris Agreement created the legal basis for international carbon market cooperation, replacing the Kyoto Protocol’s Clean Development Mechanism (CDM). It consists of three distinct pathways, finalised at COP26 in Glasgow after years of complex negotiations.

Key Feature
UPSC Relevance
6.2
Cooperative Approaches (bilateral deals)
Country-to-country trading of “Internationally Transferred Mitigation Outcomes” (ITMOs)
Bilateral agreements; corresponding adjustments avoid double-counting
6.4

Successor to CDM; supervised by Article 6.4 Supervisory Body under UNFCCC
Developing nations can participate; stricter additionality rules
6.8
Non-market Approaches
Recognises that not all climate cooperation needs to be market-based
Important for equity — covers capacity building, technology transfer
Key Concept — Corresponding Adjustment
When a country sells a carbon credit under Article 6, it must
adjust its own NDC accounting
to reflect that the reduction has been transferred. This prevents the same tonne from being counted twice — once by the selling nation and once by the buyer. This was a crucial ethical safeguard adopted at COP26 after bitter negotiations involving India, the EU, and Brazil.
09
Constitutional & Legal Dimension in India
Climate ethics through the prism of Indian law
India’s engagement with climate ethics is not merely diplomatic — it is constitutionally grounded. The Supreme Court of India and various High Courts have carved out a robust jurisprudence linking the right to a stable climate with fundamental rights.

Mains Practice — Ethics Paper IV (250 Words)
“Carbon credits are a pragmatic necessity but an ethical compromise. Critically examine this view with reference to climate justice.”
Introduction:
Carbon credits represent the intersection of market efficiency and moral obligation. While they offer a cost-effective pathway to emission reduction, their ethical foundations are contested terrain in climate justice discourse.
Pragmatic Necessity:
Globally, achieving emission targets requires enormous financial flows toward decarbonisation. Carbon markets generate over $2 billion annually in voluntary finance, channelling resources toward renewable energy and forest conservation in developing nations. For countries like India, participating in carbon markets offers green finance without compromising developmental priorities — aligning with the principle of Common But Differentiated Responsibilities (CBDR-RC).
Ethical Compromise:
The commodification of carbon raises fundamental justice concerns. First, wealthy polluters may purchase offsets instead of structural decarbonisation, violating the Kantian principle of categorical duty. Second, carbon offset projects have displaced indigenous communities in Africa and Asia — a form of carbon colonialism antithetical to distributive justice. Third, Rawlsian analysis demands we evaluate policies from the position of the worst-off; forest communities evicted for carbon credits clearly fail this test.
Nuanced View:
Carbon markets are not inherently unethical, but their design determines their moral quality. A well-designed system with rigorous additionality standards, community consent (Free Prior and Informed Consent), and a declining price floor can serve both efficiency and justice. India’s CCTS framework and the Paris Agreement’s Article 6 safeguards represent steps in this direction.
Conclusion:
Carbon credits must be judged not as abstract instruments but by their lived consequences. Where they empower communities and fund genuine reductions, they advance climate ethics; where they become licenses to pollute, they betray it.
Mains Practice — GS Paper III (150 Words)
“Discuss the key components of India’s Carbon Credit Trading Scheme (CCTS) and its significance for India’s climate commitments.”
Background:
The Energy Conservation (Amendment) Act 2022 created the statutory basis for India’s domestic Carbon Credit Trading Scheme (CCTS), operationalised through MoP notification in 2023. BEE serves as the nodal authority.
Key Components:
CCTS covers obligated entities (large energy-intensive industries) and voluntary participants. Carbon Credit Certificates (CCCs) are issued for verified emission reductions. Trading occurs on recognised exchanges (IEX, PXIL). The scheme integrates with existing PAT and REC mechanisms, streamlining India’s energy-environment market architecture.
Significance:
CCTS enables India to meet sectoral emission intensity targets while creating a domestic price signal for decarbonisation. It positions India to participate in Article 6 of the Paris Agreement, potentially generating foreign climate finance through ITMO sales. The scheme also demonstrates India’s seriousness in fulfilling its updated NDC — reducing emissions intensity by 45% by 2030 — while retaining development space for smaller industries and agriculture.
⚖ CLAT Key Points — Legal Reasoning
Climate Law & Carbon Credits for CLAT Aspirants
Principle of State Responsibility:
Under international law, states that contribute disproportionately to climate change may be liable for resulting harm — relevant in Loss and Damage claims by SIDS (Small Island Developing States)
Public Trust Doctrine:
Natural resources including clean air and climate stability are held in trust by the state for citizens — M.C. Mehta case series established this in Indian jurisprudence
Precautionary Principle:
Where there is threat of serious environmental harm, lack of full scientific certainty cannot be used as reason to postpone protective measures (Rio Principle 15)
Free Prior and Informed Consent (FPIC):
UN Declaration on Rights of Indigenous Peoples — mandatory for any carbon offset project affecting tribal/forest communities; violated in several REDD+ projects globally
Polluter Pays Principle:
Entities causing environmental damage must bear the cost of remediation — applicable to both industrial emitters and states; embedded in Indian environmental law
Carbon Credit as Property Right:
Legal debate on whether carbon credits constitute property — significant for contract law, transfer, insolvency, and taxation in domestic CCTS framework
Article 21 Climate Expansion (2024 SC):
The right to life includes right to a clean, stable climate — plaintiffs in climate litigation can now invoke fundamental rights directly

Way Forward: Ethical Carbon Markets
Reconciling efficiency with justice
The future of carbon markets depends on whether they can be reformed to serve climate justice rather than substitute for it. Several design principles are increasingly endorsed by climate ethicists, legal scholars, and developing nations.
🔍
Rigorous MRV
Measurement, Reporting, and Verification standards must be strengthened. Third-party audits, satellite monitoring of forest cover, and blockchain-based credit registries can address the integrity deficit.
🤝
Community Co-benefits
Offset projects must deliver tangible benefits to local communities — jobs, healthcare, land rights. “Carbon with Care” certification frameworks are emerging to enforce social co-benefit standards.
📈
Rising Carbon Price
A carbon price that rises predictably over time (carbon price floor) discourages over-reliance on cheap offsets and incentivises structural decarbonisation — the difference between bridge and escape valve.
🌏
Equitable Revenue Sharing
Carbon market revenues — especially from compliance markets like the EU ETS — should flow toward climate adaptation in the most vulnerable nations, aligning market efficiency with distributive justice.
India’s Opportunity
India stands at a unique position — a large emitter by absolute volume but a low per-capita emitter with vast renewable and forestry potential. A well-designed CCTS, integrated with Article 6 of the Paris Agreement, can channel global climate finance into India’s energy transition while upholding CBDR-RC principles and the rights of forest-dwelling communities.
