Green bonds are fixed-income debt instruments where the money raised is earmarked specifically for projects with environmental benefits, such as renewable energy, clean transportation, or energy efficiency. India has raised over Rs 44,000 crore (INR 440 billion) in green bonds since January 2024, with the government planning to issue Rs 15,000 crore in sovereign green bonds during the first half of FY27 alone.
How Green Bonds Work
A green bond functions like any other bond: an issuer, whether a government, corporation, or financial institution, borrows money from investors and commits to repaying it with interest over a fixed term. The distinguishing feature is that the proceeds are specifically earmarked for projects with clear environmental benefits, such as solar and wind power installations, energy-efficient buildings, clean public transportation, or sustainable water management. Consequently, green bonds allow investors to direct their fixed-income investments specifically toward climate-positive projects while still receiving the predictable returns typical of bond investments.
Who Issues Green Bonds in India?
Green bonds in India are issued by a mix of the central government, state-owned enterprises, banks, and private corporations, each using the raised capital for their own environmentally focused projects. The Reserve Bank of India has issued sovereign green bonds on behalf of the Government of India, including a 2025 re-issuance of Rs 5,000 crore in 30-year sovereign green bonds carrying a 6.98% interest rate. Additionally, various Indian corporations, particularly those in renewable energy, banking, and infrastructure, have issued their own green bonds to fund specific environmental projects, contributing to India’s cumulative green bond issuance surpassing Rs 44,000 crore since January 2024.
Green Bond Standards and Frameworks
To prevent “greenwashing,” where bond proceeds are claimed as green without genuinely funding environmental projects, most green bonds follow established frameworks like the International Capital Market Association’s Green Bond Principles, which set standards for project eligibility, use of proceeds tracking, and reporting. In India, SEBI has issued specific guidelines for green debt securities, requiring issuers to disclose how proceeds will be used and to report periodically on the environmental impact of funded projects. Consequently, investors considering green bonds can review these disclosures to verify that a bond’s proceeds are genuinely funding environmentally beneficial projects rather than simply being labeled “green” for marketing purposes.
How to Invest in Green Bonds in India
Individual investors in India can access sovereign green bonds through the RBI Retail Direct platform, which allows direct participation in government bond auctions without requiring a broker intermediary. Corporate green bonds are typically available through stock exchanges, mutual funds with green or ESG-focused bond portfolios, or directly through primary bond issuances for institutional and high-net-worth investors. Before investing, it’s worth reviewing the specific bond’s use-of-proceeds framework and reporting commitments, since not all green-labeled bonds apply equally rigorous environmental standards.
Are Green Bonds a Good Investment?
Green bonds generally offer similar risk and return characteristics to comparable conventional bonds from the same issuer, meaning the “green” label typically does not come with a significant yield sacrifice for investors seeking both financial returns and environmental impact. For investors specifically interested in supporting India’s renewable energy and sustainability transition through fixed-income investments, green bonds offer a more targeted option than general-purpose bonds.

Green Bonds vs Regular Bonds: Key Differences
Green bonds function like conventional bonds in terms of structure — they pay fixed or floating interest and return principal at maturity. The key difference lies in use of proceeds: green bond issuers must direct the raised capital exclusively toward projects with environmental benefits, such as renewable energy, clean transportation, or water management. Additionally, green bonds typically require issuers to report periodically on how proceeds were allocated and the environmental impact achieved, adding a transparency layer absent from regular bonds. However, green bonds do not usually offer higher yields than comparable conventional bonds; investors buy them primarily for portfolio alignment with sustainability goals rather than for a return premium.
