India’s green-finance market is expanding, but investment is not scaling as quickly as policy ambition because the rulebook is split among regulators, a national taxonomy is still being developed, project data and verification are uneven, and many climate projects cannot yet offer bankable risk-adjusted returns.
Growth is strong, but implementation is lagging
The market is not absent or stagnant. The Climate Bonds Initiative reported that India’s cumulative aligned green, social, sustainability and sustainability-linked (GSS+) debt reached US$55.9 billion, using 2024 data published in 2025. That was 186% above the organisation’s 2021 baseline. Green debt accounted for 83% of total issuance in figures published by the International Financial Services Centres Authority (IFSCA) in 2026.

Those figures show real demand for labelled and sustainability-linked capital. They do not, however, prove that the wider financing system is working smoothly. Issuance can grow while smaller developers, adaptation projects and first-of-a-kind technologies still struggle to secure loans or attract international investors.
Why India’s rules feel fragmented
Different parts of the market are governed by different institutions and instruments. The Reserve Bank of India (RBI) supervises banks and non-bank financial companies, including green deposits and climate-related financial-risk work. The Securities and Exchange Board of India (SEBI) sets disclosure and assurance requirements for listed entities and securities markets. The Ministry of Finance is coordinating work on a national climate-finance taxonomy, while IFSCA regulates financial activity in GIFT IFSC.
#1 Best Overall
RBI Deputy Governor M. Rajeshwar Rao described the missing foundation in two parts. He said a national taxonomy is “the first building block” for aligning government, regulators, financial institutions, borrowers and investors. He identified a second building block: a “consistent and harmonised regulatory approach” for assessing climate risk and fostering related finance.
India therefore has substantial regulation, but not yet one seamless rulebook. Requirements can differ by product, issuer, financial centre and regulator. That raises compliance costs and makes it harder for investors to compare whether two projects use the same definition of “green” or apply equivalent safeguards against greenwashing.
Rank #2
The taxonomy is not yet a single finished standard
The Union Budget 2024 announcement and subsequent technical committees put a national taxonomy on the policy agenda. Climate Bonds reported work covering energy, transport, agriculture, steel, buildings and cement. The process is important, but the cited official record does not establish that a final, economy-wide taxonomy has been completed. Until common technical thresholds are adopted and used consistently, eligibility decisions remain partly fragmented.

What is stopping more private capital
The Climate Policy Initiative (CPI) identifies three linked barriers to private investment in climate and adaptation projects: insufficient information, uncertain returns and too few bankable projects. These weaknesses are most severe where revenue arrives slowly, construction risks are high or benefits—such as flood protection—are public rather than directly monetised.
Projects are not ready for investment
A technically valuable project may still lack a feasibility study, reliable cash-flow model, land approvals, a credible offtake contract or the environmental data required by lenders. Preparation costs are incurred before financing is available, creating a gap that commercial banks rarely fill on their own.
Returns and risks are difficult to price
Climate projects can face technology, policy, currency, demand and physical-climate risks at the same time. CPI points to minimum-return assurance and public-private partnerships as ways to make otherwise viable projects investable. Guarantees, blended finance and other innovative mechanisms can allocate early-stage or construction risk to parties better able to absorb it.
Information is hard to compare
CPI says information asymmetry continues to hamper investment, particularly from private and international sources. Data may be unavailable, inconsistent across sectors or too difficult for investors to access. RBI similarly calls for better data, assurance and verification of how proceeds are used. Without credible monitoring, reporting and verification (MRV), investors face both financial uncertainty and greenwashing risk.

| Institution or policy | What changed | What remains unresolved |
|---|---|---|
| RBI green-deposit framework | Issued in April 2023, establishing requirements for banks that accept green deposits and allocate the proceeds. | Broader climate-risk methods, consistent taxonomy use and stronger end-use verification are still developing. |
| SEBI circular | The 28 March 2025 circular addressed assurance or assessment, value-chain ESG disclosures and voluntary green-credit disclosure. | Disclosure and assurance practices must become comparable across issuers and supply chains. |
| Ministry of Finance taxonomy work | The 2024 budget announcement and technical committees placed a national climate-finance taxonomy on the formal policy agenda, including energy, transport, agriculture, steel, buildings and cement. | A single final taxonomy and consistent implementation across regulators have not been established in the cited record. |
| IFSCA frameworks | GIFT IFSC has developed frameworks for GSS+ debt, ESG funds, ESG ratings and data, and transition bonds. | These frameworks operate within the IFSC and do not by themselves create one rulebook for the entire domestic market. |
| RBI regulatory sandbox | On 9 April 2025, sustainable finance and climate-risk mitigation were added to the Theme Neutral “On Tap” Regulatory Sandbox. | Sandbox experiments can test products, but successful pilots still need a route into mainstream regulation and financing. |
What a workable green-finance system needs next
- Finish and maintain a usable taxonomy. Technical criteria should identify eligible activities, transition activities and exclusions, with a process for updating thresholds as technology and climate science change.
- Harmonise supervisory expectations. RBI, SEBI, the Ministry of Finance and IFSCA need compatible definitions, climate-risk methods and disclosure calendars so the same activity is not assessed differently without a clear reason.
- Build a project-preparation pipeline. Public project-preparation facilities can fund feasibility studies, permits, engineering, legal work and MRV before a project approaches lenders.
- Improve risk sharing. Guarantees, viability-gap support, minimum-return mechanisms and carefully designed public-private partnerships can reduce risks that prevent private investment without removing commercial discipline.
- Make data and verification usable. Standardised, mandatory disclosures should be machine-readable where possible, independently assured when material, and linked to measurable environmental outcomes and verified use of proceeds.
- Develop specialist skills. RBI’s Currency and Finance 2022-23 said banks need to invest in upskilling staff across the entire credit-appraisal process. Lenders need expertise in engineering, climate science, transition plans, scenario analysis and sector-specific cash flows—not only conventional credit scoring.
How investors and borrowers should assess an opportunity
Until the framework is fully harmonised, each transaction requires its own due diligence. A lender or investor should check:
- whether the activity meets the relevant regulator’s eligibility rules and any available taxonomy criteria;
- what disclosures, assurance and value-chain information the issuer must provide;
- who bears construction, technology, transition, currency and physical-climate risks;
- whether a guarantee, minimum-return support or other credit enhancement exists;
- how complete the feasibility work, permits, contracts and financial model are;
- how emissions, adaptation outcomes and use of proceeds will be measured and verified; and
- how easily the instrument can be sold or refinanced, including the available investor liquidity.
These checks distinguish a labelled security from a genuinely investable climate asset. A green label can improve transparency, but it cannot replace a sound project, credible cash flows or independent verification.
The outlook
India has moved from limited regulatory guidance toward a more developed set of green-deposit, disclosure, assurance, transition-finance and sandbox initiatives. Issuance growth confirms that capital is available for qualifying opportunities. The next stage is execution: a common taxonomy, interoperable data, credible MRV and targeted de-risking that turns a larger share of India’s climate pipeline into projects lenders can underwrite.
Until those pieces are connected, India’s green-finance expansion is likely to remain uneven—strong in labelled debt and specialised financial centres, but slower for adaptation, smaller borrowers and projects whose public benefits are not captured by ordinary commercial returns.
