Funding India’s Climate Future: A Trillion-Dollar Question
Why in News?
India’s climate ambitions require unprecedented financial mobilisation. Achieving its updated Nationally Determined Contributions (NDCs) by 2030 and the goal of net-zero emissions by 2070 demands robust climate-finance institutions, innovative financing mechanisms, and large-scale private and public investments.
- India requires approximately ₹162.5 trillion (US$ 2.5 trillion) by 2030 to achieve its NDC targets.
- Achieving net-zero emissions by 2070 is estimated to cost around US$ 10.1 trillion, nearly three times India’s current GDP.
- The challenge lies not merely in raising funds but in building institutions capable of mobilising, de-risking, and deploying capital effectively.
Nationally Determined Contributions (NDCs)
What are NDCs?
Nationally Determined Contributions (NDCs) are climate action plans submitted by countries under the framework of the Paris Agreement.
They outline:
- Greenhouse gas (GHG) emission reduction targets.
- Adaptation and resilience-building measures.
- Sector-specific climate commitments.
Key Features
- Based on the principle of Common But Differentiated Responsibilities and Respective Capabilities (CBDR-RC).
- Countries determine targets according to their developmental needs and capacities.
- NDCs must be updated every five years with progressively higher ambition.
India’s Updated NDC Targets (2022)
India has committed to:
- Reduce the emissions intensity of GDP by 45% from 2005 levels by 2030.
- Achieve about 50% cumulative electric power installed capacity from non-fossil fuel sources by 2030.
- Create an additional carbon sink of 2.5–3 billion tonnes of CO₂ equivalent through forest and tree cover.
- Follow the Panchamrit commitments announced at COP26.
- Achieve Net Zero by 2070.
Significance of India’s NDCs
- Supports sustainable economic growth.
- Strengthens energy security.
- Promotes green industrialisation.
- Enhances climate resilience.
- Contributes to global climate mitigation efforts.
Financing Gap and Sectoral Requirements
High-Emission Sectors
The steel, cement, power, and transport sectors account for more than half of India’s emissions.
Decarbonising these sectors requires:
- US$ 467 billion additional capital expenditure (2022–2030).
- Around US$ 54 billion annually.
- Equivalent to nearly 1.3% of GDP every year.
Green Steel
Green steel is produced through:
- Renewable energy.
- Green hydrogen.
- Electric Arc Furnaces (EAFs).
- Recycled scrap steel.
Green Cement
Green cement involves:
- Alternative raw materials.
- Fly ash and slag utilisation.
- Energy-efficient technologies.
- Reduced clinker content.
Both sectors currently remain economically challenging without strong policy support and incentives.
RBI Assessment
According to the RBI:
- India needs additional green investments of at least 2.5% of GDP annually until 2030.
- Financial institutions must incorporate climate risks into lending and investment decisions.
Global Climate Finance Shortcomings
Developing Countries’ Requirement
Developing countries require approximately:
- US$ 5–6 trillion by 2030 for climate mitigation and adaptation.
Unfulfilled Climate Finance Commitments
- Developed countries pledged US$ 100 billion annually under climate agreements.
- The commitment has not been fully met.
New Collective Quantified Goal (NCQG)
At the COP29:
- Countries agreed to mobilise US$ 300 billion annually by 2035.
- India considers the target insufficient relative to developing-country needs.
Therefore, India must rely predominantly on domestic climate finance mobilisation.
Progress Made by India
By the end of 2024:
- India issued US$ 55.9 billion worth of sustainable debt instruments.
- This represents a 186% increase since 2021.
Major Instruments
Green Bonds
Debt raised exclusively for environmentally beneficial projects.
Used for:
- Renewable energy.
- Clean transportation.
- Energy efficiency.
- Climate adaptation.
Social Bonds
Finance projects such as:
- Affordable housing.
- Healthcare.
- Education.
- Employment generation.
Sustainability Bonds
Finance both environmental and social projects.
Sustainability-Linked Debt
- Interest rates linked to sustainability performance.
- Funds can be used for general corporate purposes.
Sovereign Green Bonds (SGrBs)
- Issued by the Government of India.
- ₹477 billion issued so far.
- Established pricing benchmarks and enhanced investor confidence.
Transition Finance Instruments
Support hard-to-abate sectors such as:
- Steel.
- Cement.
- Aviation.
- Thermal power.
These instruments facilitate gradual transition towards low-carbon pathways.
Infrastructure Investment Trusts (InvITs) Enable mobilisation of private capital into infrastructure projects.
Key Institutional Gaps
India still lacks several enabling mechanisms:
1. Climate Finance Taxonomy
Announced in the Union Budget 2024–25.
Needed for:
- Defining what qualifies as “green”.
- Green bond verification.
- Priority Sector Lending classification.
- Attracting international investors.
2. Credit Guarantee Architecture
Needed to reduce risk perception among investors.
3. Liquidity Support Mechanisms
Required to lower financing costs.
4. Regulatory Incentives
Green projects should receive cheaper financing than carbon-intensive projects.
5. Greenwashing Safeguards
Necessary to ensure credibility and transparency.
RBI’s Emerging Role in Climate Finance
Climate Finance and Management of Climate Change Risks Directions, 2025
The RBI has directed banks to:
- Integrate climate risks into lending decisions.
- Strengthen climate risk management frameworks.
- Incorporate environmental risk assessments.
Major Provisions
Priority Sector Lending (PSL)
Eligible green activities may qualify under PSL.
Benefits:
- Increased credit flow.
- Lower borrowing costs.
- Greater private sector participation.
Recognition of Sovereign Green Bonds
Investments in Sovereign Green Bonds receive regulatory support.
Measures RBI Can Further Adopt
Green Supporting Factors
- Lower reserve requirements for green lending.
- Preferential collateral treatment for Sovereign Green Bonds.
Brown Penalising Factors
- Higher capital requirements for carbon-intensive lending.
Climate Stress Testing
Assess banking sector vulnerability to:
- Floods.
- Cyclones.
- Heatwaves.
- Transition risks.
Regulatory Sandbox
Promotes experimentation in:
- Green fintech.
- Sustainable lending products.
- Climate-risk management tools.
Climate Risk Information System (CRIS)
Objective
A comprehensive repository of climate-risk data for financial institutions.
Functions
Helps assess:
Physical Risks
- Floods.
- Cyclones.
- Droughts.
- Heatwaves.
Transition Risks
- Carbon regulations.
- Technology shifts.
- Decarbonisation policies.
Benefits
- Better lending decisions.

Importance of Climate Finance Taxonomy
Why It Matters?
A taxonomy provides a legally recognised classification of sustainable economic activities.
Benefits
- Prevents greenwashing.
- Standardises reporting.
- Supports green bond markets.
- Facilitates foreign investment.
- Improves transparency.
Green Steel Taxonomy
The Ministry of Steel is developing a dedicated Green Steel Taxonomy to support decarbonisation of the steel sector.
Conclusion
India’s climate transition is fundamentally a financing challenge. While the country has made significant progress through green bonds, sovereign green bonds, and sustainable finance initiatives, achieving its NDC targets by 2030 and net-zero by 2070 will require a comprehensive climate-finance ecosystem. Strengthening institutions, operationalising a climate finance taxonomy, empowering states, and leveraging blended finance will be critical to mobilising the trillions of dollars required for a low-carbon and climate-resilient future.
