BharatNotes Overview
Climate diplomacy has become one of the most consequential arenas of international relations in the 21st century. India — the world's third-largest emitter of greenhouse gases in absolute terms but with per capita emissions far below the global average — occupies a unique position. It demands climate justice based on the principle of Common But Differentiated Responsibilities (CBDR), while simultaneously leading global initiatives like the International Solar Alliance (ISA), the Coalition for Disaster Resilient Infrastructure (CDRI), and the Lifestyle for Environment (LiFE) movement. This chapter examines India's evolving climate positions from Copenhagen to Belém (COP30, November 2025), its leadership of green initiatives, governance of global commons, and the complex politics of climate finance.
India's Core Climate Positions
Common But Differentiated Responsibilities (CBDR-RC)
| Concept | Detail |
|---|---|
| Origin | Principle 7 of the Rio Declaration (1992) at the Earth Summit |
| Full name | Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC) |
| Core idea | All nations share responsibility for addressing climate change, but developed countries bear greater responsibility because they have historically emitted the most and have greater financial and technological capacity |
| India's position | India consistently argues that developed nations (responsible for ~79% of cumulative CO2 emissions since 1850) must take the lead in mitigation and provide finance and technology to developing countries |
| Legal basis | Enshrined in UNFCCC (1992), Kyoto Protocol (1997), and the Paris Agreement (2015) — though Paris shifted toward self-determined nationally determined contributions (NDCs) |
Per Capita Emissions Argument
| Metric | India | USA | China | EU | World Average |
|---|---|---|---|---|---|
| Per capita CO2 (2023, approx.) | ~2.0 tonnes | ~14 tonnes | ~8 tonnes | ~6 tonnes | ~4.7 tonnes |
| Share of global emissions | ~7% | ~13% | ~30% | ~7% | — |
| Historical cumulative emissions | ~3--4% | ~25% | ~13% | ~22% | — |
India's per capita emissions are approximately half the global average and a fraction of developed nations' per capita emissions. This is the foundation of India's demand for equitable climate action and climate justice.
Climate Justice
| Dimension | India's Argument |
|---|---|
| Historical responsibility | The climate crisis was created by industrialised nations over 200+ years; developing countries should not bear equal mitigation burden |
| Development rights | India has the right to develop its economy and lift millions out of poverty; climate action cannot come at the cost of development |
| Technology transfer | Developed countries must transfer clean energy technologies at affordable cost — not just sell them at commercial rates |
| Climate finance | Developed countries must honour their financial commitments — the $100 billion/year promise (from 2009 Copenhagen) was met with significant delays and creative accounting |
| Adaptation equity | Developing countries face the worst impacts of climate change but have contributed the least — they need adaptation finance, not just mitigation targets |
Mains Favourite: "India contributes only 7% of global emissions but faces some of the worst climate impacts. Discuss India's climate justice argument and its implications for global climate negotiations." A strong answer should cover CBDR, per capita vs absolute emissions, historical responsibility, development rights, and the need for climate finance.
India at Major COPs — A Timeline
Copenhagen (COP15, 2009)
| Feature | Detail |
|---|---|
| India's position | Led by PM Manmohan Singh; India resisted legally binding emission cuts for developing countries |
| Key outcome | Copenhagen Accord — non-binding; developed countries pledged $100 billion/year by 2020 in climate finance (not met on time) |
| India's commitment | Voluntary pledge to reduce emissions intensity of GDP by 20--25% by 2020 over 2005 levels (achieved ahead of schedule) |
| Significance | Marked the emergence of BASIC bloc (Brazil, South Africa, India, China) as a negotiating force |

| Additional layer | A broader aspiration of mobilising up to $1.3 trillion (primarily from private sources) |
| Developing country reaction | Many developing countries (including Bolivia, Nigeria, small island states) called the $300 billion "insultingly low" — they had demanded $1.3 trillion in public finance |
| India's position | Supported the goal as a floor, not a ceiling; demanded clearer accounting and transparency; pushed for grant-based rather than loan-based financing |
| Baku-to-Belém Roadmap | COP29 and COP30 Presidencies jointly unveiled the Baku-to-Belém Roadmap — a blueprint to mobilise at least $1.3 trillion/year in climate finance by 2035; the roadmap provides a framework for grants, concessional finance, and private sector leverage |

Climate Finance
The $100 Billion Promise
| Feature | Detail |
|---|---|
| Origin | COP15 Copenhagen (2009) — developed countries committed to mobilise $100 billion per year by 2020 for climate action in developing countries |
| Delivery | The target was reportedly met for the first time in 2022 — two years late — and with significant reliance on loans rather than grants |
| Criticism | Developing countries argue that much of the "climate finance" counted was repurposed development aid, commercial-rate loans, or private investment — not new, additional, grant-based public finance |
| India's position | Demands transparent accounting; insists on grant-based finance; argues that loans increase debt burden of developing countries |
New Collective Quantified Goal (NCQG) — COP29
| Feature | Detail |
|---|---|
| Agreed at | COP29 Baku (November 2024) |
| Core target | $300 billion per year by 2035 from developed to developing countries |
| Additional layer | Aspiration of mobilising $1.3 trillion (including private sector) |
| Controversy | Developing countries demanded $1.3 trillion in public finance; $300 billion called "insultingly low" by several nations |
| India's critique | Supported $300B as a floor; demanded grant-dominant funding, not loans |
Loss and Damage Fund
| Feature | Detail |
|---|---|
| Established | COP27 Sharm el-Sheikh (2022) — decision to create the fund |
| Operationalised | COP28 Dubai (December 2023) — adopted on day one of the summit |

| India's access | India accesses GCF through accredited entities (NABARD is India's Direct Access Entity); funded projects include coastal resilience, solar energy, and sustainable agriculture |
EU CBAM — Carbon Border Adjustment Mechanism
| Feature | Detail |
|---|---|
| What | A tariff mechanism that imposes a carbon price on imports based on their embedded carbon content — applicable to cement, iron and steel, aluminium, fertilisers, electricity, and hydrogen |
| Transitional phase | 1 October 2023 -- 2025 (reporting only) |
| Definitive phase | From 2026 — importers must purchase CBAM certificates |
| Impact on India | Affects ~$8.2 billion worth of Indian exports to the EU (27% of iron/steel and aluminium exports); estimated price burden of ~25% on affected steel and aluminium exports |
| India's response | (1) Called CBAM a potential trade barrier that contradicts CBDR; (2) Exploring domestic carbon pricing (Emissions Trading System under development); (3) Engaging with EU through technical dialogues (DG TAXUD-India meetings, 2024); (4) Considering advocacy for equitable redistribution of CBAM revenues to affected developing countries |
| UPSC angle | CBAM raises questions about trade-climate nexus, equity, WTO compatibility, and the future of CBDR |
Mains Favourite: "The EU's CBAM threatens to shift the climate burden onto developing countries. Critically examine India's options." Cover: (1) What CBAM is and how it works, (2) Impact on Indian exports, (3) India's climate justice argument (CBDR, per capita emissions), (4) Policy options (domestic carbon pricing, FTA negotiations, WTO challenge, coalition-building with other developing countries).
Climate Litigation and Emerging Trends
| Trend | Detail |
|---|---|
| Global rise | Over 2,600 climate litigation cases filed worldwide as of 2024; courts increasingly holding governments and corporations accountable for climate action |

Recent Developments (2024–2026)
COP29 Baku — NCQG and India's Criticism (November 2024)
COP29 was held in Baku, Azerbaijan, from 11–22 November 2024. The centrepiece outcome was the New Collective Quantified Goal (NCQG) on climate finance — developed countries pledged to mobilise at least USD 300 billion per year by 2035 for developing countries. However, India strongly criticised this figure as "abysmally poor" and an "optical illusion," calling it far short of the USD 1 trillion per year that developing nations had demanded based on independent expert estimates. India's Environment Minister described the agreement as reflecting the "unwillingness of developed countries to engage seriously" on climate finance.
India's key positions at COP29: push for NCQG of at least USD 1 trillion per year; removal of IPR barriers on green technologies for developing countries; application of CBDR in mitigation work programmes; and ensuring private finance is additional to, not substituted for, public finance.
UPSC angle: COP29 (Baku, November 2024), NCQG (USD 300 billion/year, 2035), India's criticism ("optical illusion"), India's advocacy for USD 1 trillion climate finance, and the launch of the Baku-to-Belém Roadmap (pathway to $1.3 trillion/year by 2035) are high-priority Prelims 2027 topics. The NCQG replaces the previous USD 100 billion per year goal (from Copenhagen 2009).
India's Climate Targets — NDC Update and 2030 Progress
India submitted its updated Nationally Determined Contribution (NDC) in August 2022, targeting: 45% reduction in emissions intensity of GDP by 2030 (from 2005 levels); 50% of cumulative electric power from non-fossil fuel-based energy sources by 2030; and creation of an additional carbon sink of 2.5–3 billion tonnes of CO2 equivalent through forest and tree cover. As of 2024, India had achieved 44.5% of its electricity from non-fossil sources (RE + nuclear + hydro). By November 2025, India's non-fossil capacity stood at approximately 256 GW — constituting over 50% of total installed electricity capacity (as stated by Environment Minister Bhupender Yadav at COP30, November 2025), meaning India has achieved the 50% non-fossil power NDC target five years ahead of schedule. India has also pledged to achieve net-zero emissions by 2070.
At COP30 (November 17, 2025), India announced it would submit its NDC 3.0 (covering 2031–2035 targets) by December 2025.
UPSC angle: India's NDC 2022 targets — 45% emissions intensity reduction, 50% non-fossil power by 2030, net-zero by 2070. India achieved the 50% non-fossil NDC target in 2025, five years early. India's NDC 3.0 commitment (COP30, December 2025) are essential Prelims 2027 and Mains 2026 facts.
ICJ Advisory Opinion on Climate Obligations — July 2025
The International Court of Justice (ICJ) issued its Advisory Opinion on the Obligations of States in respect of Climate Change on 23 July 2025 — unanimously, and for the first time in the ICJ's history on this topic. Key holdings: states have legal obligations to prevent significant harm to the climate under customary international law, international human rights law, and climate treaties; the 1.5°C Paris target carries legal weight; all states — especially the largest emitters — must take ambitious mitigation measures consistent with the best available science; CBDR and the precautionary principle apply as interpretive frameworks. While non-binding, the opinion provides strong legal grounding for domestic climate litigation worldwide.
India participated in oral hearings (December 2024), arguing for the primacy of CBDR and the right of developing nations to equitable climate space. India's CBDR argument was reflected in the Court's reasoning.
UPSC angle: ICJ Climate Advisory Opinion (23 July 2025) — first-ever; unanimous; 1.5°C as legally weighty obligation; CBDR affirmed; links climate diplomacy (GS-II) with international law (GS-II) and climate litigation (emerging). High Prelims 2027 probability.
High Seas Treaty — India's Ratification Status
The UN High Seas Treaty (BBNJ Agreement) was adopted in June 2023 and entered into force on 17 January 2026, after reaching the required 60 ratifications on 19 September 2025 (Sierra Leone and Morocco were the 60th and 61st ratifying states). The treaty governs conservation of marine biodiversity in areas beyond national jurisdiction (the "high seas"), covering approximately 64% of the ocean surface. India signed the treaty and is working towards ratification.
UPSC angle: BBNJ Agreement/High Seas Treaty — adopted June 2023, 60 ratifications reached 19 September 2025, entered into force 17 January 2026; covers high seas biodiversity; India's signature and pending ratification. This is a "common heritage of mankind" principle application.
India and CBAM — EU Carbon Border Adjustment Mechanism Challenge
The EU's Carbon Border Adjustment Mechanism (CBAM) — entering into full effect from 2026 — will impose a carbon price on imports of certain carbon-intensive goods (steel, aluminium, cement, fertilisers, electricity, hydrogen) from countries without equivalent carbon pricing. India, a major exporter of steel and aluminium to the EU, has challenged CBAM as a trade barrier inconsistent with WTO rules and CBDR principles. India argues CBAM imposes the EU's carbon accounting methodology on developing countries and discriminates against lower-income exporters.
UPSC angle: EU CBAM (full enforcement 2026), India's opposition (WTO inconsistency, CBDR violation), affected sectors (steel, aluminium, cement, fertilisers) — critical for both GS-II (climate diplomacy) and GS-III (trade policy, Indian industry).
COP30 Belém — Key Outcomes (November 2025)
COP30 was held in Belém, Brazil, from 10–21 November 2025 under Brazil's COP presidency (part of the Troika: UAE-COP28, Azerbaijan-COP29, Brazil-COP30). The centrepiece outcome was the "Mutirão" package (Portuguese for "collective effort"). Key outcomes: (1) tripling adaptation finance by 2035 (from the original 2030 target, weakened in negotiations); (2) a decision to "urgently advance actions" to scale up climate finance to $1.3 trillion/year; (3) the Tropical Forests Forever Fund raised to $5.5 billion with 53 participating countries, and at least 20% going directly to Indigenous Peoples and local communities; (4) a new Belém Mechanism for Just Global Transition; (5) a new Belém Gender Action Plan. Notably, the final text did not include a binding fossil fuel phase-out roadmap — the COP30 Presidency announced a separate roadmap on fossil fuel transition outside formal negotiations.
India's NDC 3.0 commitment: at COP30 (November 17, 2025), India's Environment Minister Bhupender Yadav announced India would submit an updated NDC for the 2031–2035 period by December 2025. He highlighted that India's non-fossil fuel capacity stands at ~256 GW — over half of total installed capacity — meeting the 50% non-fossil NDC target five years ahead of schedule.
UPSC angle: COP30 Belém (November 2025) — Mutirão package, Troika presidencies (UAE-Azerbaijan-Brazil), Baku-to-Belém Roadmap, India's NDC 3.0 announcement, and $5.5B Tropical Forests Forever Fund are new high-priority Prelims 2027 facts. The absence of a binding fossil fuel roadmap in formal text is an important analytical point.
India's Renewable Energy Progress — Solar and Wind (2025)
India's installed renewable energy capacity reached approximately 253.96 GW by November 2025 (solar: ~132.85 GW, wind: ~53.99 GW, hydro: ~47 GW, others). India crossed the 100 GW solar milestone in January 2025 and 50 GW wind milestone in March 2025 — both ahead of target. India added a record 44.5 GW of renewable energy capacity in 2025 (up to November), nearly double the 24.72 GW added in the same period of 2024. India is on track to meet its 500 GW non-fossil fuel target by 2030. India's solar manufacturing capacity expanded significantly under the Production-Linked Incentive (PLI) scheme for solar PV modules. India also launched the PM Surya Ghar Muft Bijli Yojana (Pradhan Mantri Surya Ghar Scheme, February 2024) for rooftop solar for 10 million households.
UPSC angle: India's RE capacity milestones — 253.96 GW total RE by November 2025 (solar ~132.85 GW, wind ~53.99 GW), 100 GW solar crossed January 2025, 50 GW wind crossed March 2025, record 44.5 GW added in 2025 — are important GS-III energy and GS-II climate diplomacy data points. India is the third-largest in renewable energy installed capacity globally (per Ministry of New and Renewable Energy, 2025).
Vocabulary
Key Terms
Global Commons
- Definition: Global Commons are resource domains that lie outside the national jurisdiction of any single state and to which all nations have access. International law traditionally recognises four such commons: the High Seas, the Atmosphere, Antarctica and Outer Space.
- Context: Because no state owns them, the global commons are governed through multilateral treaties guided by principles such as the "common heritage of mankind", first applied to the deep seabed by UN General Assembly Resolution 2749 (1970) and codified in Article 136 of UNCLOS (adopted 1982, in force 16 November 1994). Garrett Hardin's 1968 essay "The Tragedy of the Commons" framed the core governance problem — unrestricted access leads to over-exploitation. The concept has gained renewed salience with the BBNJ (High Seas) Agreement, adopted on 19 June 2023, which entered into force on 17 January 2026 after crossing 60 ratifications in September 2025. Some scholars now extend the idea to cyberspace and biodiversity, though these lack the same legal status.
- UPSC Relevance: A foundational GS2 (International Relations) and GS3 (Environment) concept — it underpins questions on UNCLOS and the High Seas Treaty, the Antarctic Treaty System and the Indian Antarctic Act 2022, outer space governance, and climate negotiations. Prelims typically tests which domains qualify as global commons and the treaties governing each; Mains questions probe governance gaps, the common-heritage-of-mankind principle, and India's stakes in deep-sea mining, Antarctica and space. No specific PYQ is cited here, but the theme recurs across questions on oceans, Antarctica and international environmental law.
Common But Differentiated Responsibilities
- Definition: Common But Differentiated Responsibilities (CBDR) is a foundational principle of international environmental law holding that while all states share a common obligation to protect the global environment, their specific responsibilities differ according to their historical contribution to the problem and their respective economic and technological capabilities — placing the lead burden on developed countries.
- Context: CBDR was formally articulated as Principle 7 of the 1992 Rio Declaration and embedded in the United Nations Framework Convention on Climate Change (UNFCCC), 1992, particularly Article 3. It reflects the recognition that industrialised nations contributed disproportionately to cumulative greenhouse-gas emissions and possess greater financial and technological means to respond. The principle drove the dichotomy between Annex I (developed) and non-Annex I (developing) countries in the Kyoto Protocol, 1997, and later evolved into the more flexible CBDR-RC formula ("respective capabilities, in the light of different national circumstances") under the Paris Agreement, 2015.
- UPSC Relevance: CBDR is a high-yield GS2 (international relations, global groupings, agreements involving India) and GS3 (environment, climate change) concept. In Mains, it underpins answers on climate-finance equity, India's negotiating position, and North-South divides in environmental governance; in Prelims it supports questions on the UNFCCC, Kyoto Protocol, and Paris Agreement architecture. Foundational concept — no direct standalone PYQ is cited here, but it underpins recurring questions on the climate-change negotiation regime and India's stance on climate justice.
International Solar Alliance (ISA)
- Pronunciation: /ˌɪn.təˈnæʃ.ən.əl ˈsəʊ.lər əˈlaɪ.əns/
- Definition: A treaty-based international organisation co-founded by India and France at COP21 Paris on 30 November 2015, headquartered in Gurugram, Haryana, with the objective of promoting solar energy deployment, mobilising investment ($1 trillion target by 2030), reducing technology costs, and building capacity in solar-resource-rich countries.
- Context: Became a treaty-based organisation in December 2017; 125 signatories and 107+ full voting members (as of 8th ISA Assembly, April 2025 — expanded from 47 members in 2018); India is president, France is co-president (2024--2026); key initiative: One Sun One World One Grid (OSOWOG) — a global interconnected solar energy grid.
- UPSC Relevance: GS2 (International Relations) and GS3 (Environment). Prelims: founding date (November 2015, COP21), co-founders (India and France), HQ (Gurugram, Haryana), membership (~120 countries). Mains: evaluate ISA's effectiveness in promoting solar energy in developing countries; assess India's leadership in global renewable energy governance.
Panchamrit
- Pronunciation: /ˈpʌn.tʃɑːm.rɪt/
- Definition: The five climate action pledges announced by PM Modi at COP26 Glasgow in November 2021, comprising: (1) 500 GW non-fossil energy capacity by 2030, (2) 50% energy from renewables by 2030, (3) reduce total projected carbon emissions by 1 billion tonnes by 2030, (4) reduce carbon intensity of GDP by 45% over 2005 levels by 2030, and (5) achieve net-zero emissions by 2070.
- Context: "Panchamrit" means "five nectars" in Sanskrit — derived from the five sacred ingredients (milk, curd, ghee, honey, sugar) offered in Hindu rituals; these pledges were formally incorporated into India's updated NDC in August 2022.
- UPSC Relevance: GS2 (International Relations) and GS3 (Environment). Prelims: all five targets are frequently tested — memorise the specific numbers (500 GW, 50%, 1 billion tonnes, 45%, 2070). Mains: evaluate whether India's Panchamrit pledges are achievable and sufficient; compare India's net-zero target (2070) with other major emitters.
