Climate Finance: Methods, Initiatives & Challenges

Context (LM): India requires $1.5 trillion by 2030 to achieve its climate and energy targets, as stated in Deloitte’s ‘The Climate Response’ report.

The report estimates $250 bn required for non-fossil fuel capacity and $300 bn for energy storage expansion, highlights investment gaps in renewables, biofuels, green hydrogen, grid, & storage systems.

What is Climate Finance?

The UNFCCC defines climate finance as multi-source public and private funding that supports mitigation & adaptation to climate change.
Article 9 of the Paris Agreement obligates developed countries to mobilize $100 billion each year for developing nations until 2025.
- The obligation is based on the principle of common but differentiated responsibilities and respective capabilities (CBDR-RC).

Green Bonds: Debt securities issued to raise capital for environment-friendly projects.
Climate Funds: Public or multilateral funds financing mitigation & adaptation in developing countries.
Blended Finance: Risk-sharing models combining public and private finance to fund climate projects.
Carbon Credits: Market instruments to offset emissions by purchasing certified emission reductions.
Debt Swaps: Restructuring of external debt into domestic investments in climate-related initiatives.
Concessional Loans: Below-market loans provided with favourable terms for climate action.
Grants: Non-repayable financial aid supporting vulnerable regions’ mitigation and adaptation goals.
Guarantees: Risk-reduction instruments ensuring lender recovery in case of project failure.

Scale: Global climate finance flows crossed $2 trillion in 2024, reflecting rising investment momentum.
Mitigation Dominance: ~90% of global flows support mitigation, sidelining urgent adaptation needs.
Adaptation Deficit: Only ~$65 billion supported adaptation in 2023 (~3.4%), far below required levels
Private Share: ~49% came from private sources, primarily for return-driven mitigation projects.
Dual-Benefit Funding: Only ~3% supported activities with both mitigation and adaptation impacts.
Emerging Markets: They received ~59% of total flows, mostly from international public sources.
Debt-Based Finance: Around 69% of total flows were delivered through debt or equity instruments.

Climate finance systems worldwide, including India, face persistent challenges like low adaptation share, debt-heavy flows, and institutional inefficiencies.
- Barriers to access, equity, and fund alignment continue to hinder effective mobilisation in climate-vulnerable regions.

Definition Gap: Absence of a universal definition weakens transparency & cross-country comparability.
Inflated Reporting: Donor countries overstate contributions using flawed accounting.
Adaptation Bias: Around 5% of total climate finance supports adaptation in vulnerable countries.
Debt Dominance: ~69% of finance is debt-based, deterring adaptation and exacerbating fiscal burdens.
Weak Accountability: No binding enforcement exists to penalise failures in climate finance obligations.

Private Gap: Adaptation finance suffers due to weak returns and low investor interest.
Project Risk: Long gestation periods deter banks from financing green infrastructure projects.
Debt Barrier: Rising debt levels reduce India’s access to concessional global climate finance.
Policy Misfit: India’s frameworks often diverge from multilateral fund access requirements.
Urban Skew: Climate finance disproportionately favours urban over rural, vulnerable regions.

NCEF: The National Clean Energy Fund uses coal cess revenue for clean tech R&D and deployment.
NAFCC: The National Adaptation Fund funds climate resilience projects in vulnerable states.
Sovereign Green Bonds: Introduced in Budget 2022-23 to finance green public infrastructure.
RBI SFG: The RBI’s Sustainable Finance Group frames green finance and disclosure norms.
Priority Lending: RBI includes renewables in the priority sector to boost credit flow to green sectors.
NABARD Strategy: NABARD’s 2030 strategy broadens rural green finance and resource mobilisation.
GCF Access: India accesses the Green Climate Fund for adaptation and clean energy investments.

Concessional Fund: India should replicate UAE’s $30 billion concessional fund to attract private capital.
Debt Swap: Use debt-for-climate swaps, like Belize, to redirect repayments into climate projects.
Unified Fund: A national climate fund, like Brazil’s Amazon Fund, can centralise climate disbursal.
Transition Partnership: Adopt a JETP-like model to attract blended finance for coal transition.
Finance Timelines: Predictable multi-year pledges, as in Germany, improve investment certainty.
Budget Tagging: Chile’s fiscal tagging model can help transparently track green public expenditure.

JETP: The Just Energy Transition Partnership is a G7-led initiative to mobilise climate finance for the coal phase-out and clean energy in emerging economies.
