Introduction
India and China together account for roughly 38% of global greenhouse gas emissions and represent the world's most populous developing economies. With their respective Net Zero commitments (China by 2060 and India by 2070), bilateral and multilateral cooperation between the two Asian giants is indispensable for keeping global temperature targets within reach, despite complex geopolitical headwinds.
Opportunities for Climate Cooperation
- Multilateral Coalitions and UNFCCC Negotiations: Through negotiating blocs like BASIC (Brazil, South Africa, India, China) and LMDC (Like-Minded Developing Countries), both nations present a unified voice demanding climate justice, the enforcement of Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC), and adequate climate finance from the Global North under the New Collective Quantified Goal (NCQG).
- South-South Multilateral Financing: Leveraging institutions such as the New Development Bank (NDB) and the Asian Infrastructure Investment Bank (AIIB) allows both countries to mobilize affordable capital for clean energy infrastructure across the Global South.
- Himalayan Transboundary Governance: The Himalayas, often termed the 'Third Pole', face acute threats from glacial melt and extreme weather. Bilateral coordination on hydrological data sharing, flood early-warning systems, and glaciological research (such as along the Brahmaputra/Yarlung Tsangpo basin) is critical for regional water and ecological security.
- Green Tech Sharing and Urban Resilience: Joint technical cooperation in urban heat mitigation, public transport electrification, and mass low-carbon manufacturing can significantly reduce the costs of decarbonization.
Challenges and Strategic Vulnerabilities
- Supply Chain and Clean-Tech Asymmetry: India faces acute structural dependence on Chinese clean-tech inputs. China processes roughly 75% of global cobalt and 65% of global lithium, and supplies over 99% of India's solar wafers, creating serious energy security concerns for New Delhi.
- Geopolitical Mistrust and Border Frictions: Ongoing disputes along the Line of Actual Control (LAC) impede broader diplomatic engagement. Post-2020 regulatory restrictions, such as Press Note 3 regulating foreign direct investment from bordering nations, restrict Chinese investments and joint ventures in India's battery and EV sectors.
- Competition for Critical Minerals: Both nations are actively competing for mineral concessions (lithium, cobalt, rare earth elements) across Africa, Latin America, and Central Asia, fostering a zero-sum commercial rivalry rather than resource collaboration.
- Divergent Green-Trade Strategies: Although both countries oppose protectionist instruments like the European Union's Carbon Border Adjustment Mechanism (CBAM), competitive anxieties in export manufacturing hinder the development of a joint counter-strategy.
Way Forward
- De-risking without Decoupling: India can foster strategic autonomy by building domestic manufacturing capacities via the Production Linked Incentive (PLI) scheme and the Approved List of Models and Manufacturers (ALMM), while keeping targeted trade lines open.
- Ring-fenced Green Diplomacy: Establishing an institutionalized bilateral 'Green Corridor Dialogue' focused specifically on disaster risk reduction, Himalayan ecological resilience, and joint scientific modeling can insulate urgent ecological imperatives from military and border standoffs.
Conclusion
Global climate stabilization is impossible without substantive climate action across Asia. While bilateral security tensions remain significant, ring-fencing climate diplomacy and collaborating on shared ecological vulnerabilities can transform climate action into a stabilizing bridge in India-China relations.
