New Delhi – The government plans to raise 15,000 crore rupees through sovereign green bonds in the first half of financial year 2026-27, continuing a programme that began with an 8,000 crore issue in January 2023.
The mechanics are split across two institutions. The Ministry of Finance sets the framework and decides which projects qualify. The Reserve Bank of India issues the paper on behalf of the government and runs the auction and settlement, including access for retail investors through RBI Retail Direct.
What the money may fund
The sovereign green bond framework, published in 2022, defines eligible categories: renewable energy, clean transportation, sustainable water and waste management, energy efficiency, green buildings, biodiversity and climate adaptation.
The framework is deliberately aligned with international green bond standards, which matters for the investor base. A framework that diverges from recognised principles limits participation by funds with their own mandate constraints.
The greenium question
The recurring issue with Indian sovereign green paper has been pricing. In theory a green bond should clear at a marginally lower yield than a conventional bond of the same tenor, the difference being the greenium, reflecting demand from mandate-constrained buyers.
In practice that discount has been thin and inconsistent across Indian issues. Where the government borrows green at effectively the same cost as conventional debt, the instrument delivers transparency about use of proceeds without delivering cheaper funding.
Whether the 2026-27 issues attract a firmer greenium is the number worth watching, because it determines whether green issuance stays a policy signal or becomes a genuine funding strategy.
Reporting is where credibility is earned
Green bond frameworks stand or fall on allocation and impact reporting: where the money actually went, and what it achieved in measurable terms. Proceeds that flow into projects already funded from general revenue raise the question of whether anything additional happened at all.
For investors, allocation reporting is the document to read. It is the only disclosure that connects the label on the bond to activity in the world.
