What is a green bond in simple words?

A green bond is money borrowed through a bond for projects that meet stated environmental criteria. The borrower pays interest and repays the principal, while the proceeds are tracked for eligible green uses.

Who issues green bonds in India?

The Government of India, companies, banks, financial institutions and municipal corporations can issue green bonds, subject to the rules that apply to the particular instrument and market.

How much has the Government of India raised through Sovereign Green Bonds?

Official data show issuance of about ₹72,697 crore from FY2022-23 through FY2025-26. The H1 FY2026-27 government borrowing programme provided for another ₹15,000 crore.

Are green bonds safer than normal bonds?

Not necessarily. The green label describes the use of the money, not the issuer's ability to repay. Credit risk, maturity risk, interest-rate risk and liquidity still need to be evaluated.

Do green bonds always offer lower interest rates?

No. India's Economic Survey estimates the Sovereign Green Bond pricing benefit at around 0 to 6 basis points and says it has not been consistent.

Are municipal green bonds growing in India?

Yes, more cities have entered the market, although total issuance remains small compared with sovereign borrowing.

India's green bond market is no longer a niche segment of climate finance. It has evolved into a structured public-policy mechanism and a mainstream financing instrument.

Since the Centre entered the market in FY2022-23, the Government of India has raised about ₹72,697 crore through Sovereign Green Bonds across four financial years. This includes ₹16,000 crore in FY2022-23, ₹20,000 crore in FY2023-24, ₹21,697 crore in FY2024-25, and ₹15,000 crore in FY2025-26. For the first half of FY2026-27, the government scheduled another ₹15,000 crore, split across three ₹5,000 crore tranches. If completed as planned, this would take cumulative sovereign green bond mobilisation since FY2022-23 to about ₹87,697 crore. (Source: Economic Survey 2025-26)

The money is tied to identified public spending. The Union Budget 2026-27 lists ₹30,941.30 crore of proposed expenditure eligible for financing under the Sovereign Green Bond framework in FY2026-27. In FY2024-25 alone, actual eligible green expenditure reached ₹30,274.47 crore, compared with ₹21,697.40 crore raised through Sovereign Green Bonds. The remaining ₹8,577.07 crore came from general government revenue.

The market is also spreading beyond central government borrowing. SEBI's ESG Debt Securities database recorded ₹21,678.59 crore of cumulative listed ESG debt issuance as of June 30, 2026. This point-in-time figure includes a ₹10,000 crore green bond issued by Bank of Baroda in March 2026, along with issues from renewable-energy companies, financial institutions, and municipal corporations.

What Are Green Bonds?

A green bond works much like a regular bond. A government, company, bank, or municipal body borrows money from investors and agrees to pay interest and repay the principal according to the terms of the bond. The critical difference is the Use of Proceeds.

Money raised through a green bond is earmarked strictly for eligible projects with environmental outcomes. In India, these can include renewable energy, electric public transport, energy efficiency, climate adaptation, water treatment, pollution control, green buildings, biodiversity protection, and sustainable land management.

Distinguishing the Label from Verified Impact

It is vital to understand that a "green bond" label indicates the intended use of the borrowed money; it does not automatically guarantee a verified reduction in carbon emissions at the time of purchase. True environmental impact is proven through a strict life-cycle: a use-of-proceeds framework, independent project selection, post-issuance impact reporting, and external third-party review. Without these, the label is just a marketing term.

The Major Types of Green Bonds in India

The green debt market is not monolithic. It is segmented by issuer type, each governed by different risk profiles and regulatory frameworks.

Sovereign Green Bonds (SGrBs): Issued by the Government of India. The proceeds fund public climate and environmental projects. These carry the sovereign credit rating (zero default risk in local currency) and are regulated by the RBI and the Department of Economic Affairs (DEA).
Corporate Green Bonds: Issued by private companies, public sector undertakings (PSUs), or financial institutions (like Bank of Baroda). Proceeds fund corporate transitions, such as building a solar park. These carry the specific credit risk of the issuing corporation and are regulated by SEBI's ESG debt framework.
Municipal Green Bonds: Issued by urban local bodies (e.g., Vadodara Municipal Corporation, Indore Municipal Corporation). Proceeds fund localized infrastructure like sewage treatment plants or solar-powered water pumps. These carry the credit risk of the municipality and often require structured payment mechanisms to ensure repayment.
Other Sustainable Debt: The market is expanding into "Blue Bonds" (ocean and water conservation), "Social Bonds" (affordable housing), and "Sustainability-Linked Bonds" (where the interest rate changes if the company fails to meet a specific emissions target).

Where Does the Money Go? (Project Examples)

In a green bond, traceability is everything. According to Statement 15A of the Union Budget Expenditure Profile, the ₹30,274.47 crore of actual green expenditure in FY2024-25 was allocated to specific, documentable projects:

Railway-related eligible expenditure (₹14,996.29 crore): Electrification of tracks and energy-efficient locomotive upgrades.
Solar Programmes (₹7,007.46 crore) & PM-KUSUM (₹1,496 crore): Subsidizing solar installations and providing solar-powered agriculture pumps to farmers, reducing reliance on diesel generators.
Metro Equity Investment (₹5,566.43 crore): Expanding clean, mass urban transit systems across major Indian cities to offset vehicular carbon emissions.
National Green Hydrogen Mission (₹304 crore): Seed funding for the development of clean hydrogen fuel infrastructure.

Understanding Investor Risks

The word "green" does not mean "risk-free." Investors evaluating a green bond must look beyond the environmental label and assess core financial metrics.

Credit Risk & Issuer Default: For corporate and municipal bonds, if the issuing entity goes bankrupt, investors can lose their principal. The green nature of the project does not shield investors from corporate insolvency.
Interest-Rate Risk: Like all fixed-income securities, existing bond prices fall when broader market interest rates rise.
Liquidity Risk: The secondary market for green bonds in India is still developing. Investors might find it difficult to sell a green bond before maturity without taking a discount, as trading volumes are lower than standard government securities.
Greenwashing Risk: The risk that the issuer exaggerates the environmental benefits of the funded projects or redirects funds to non-eligible activities. This highlights the limitations of purely voluntary environmental claims.

How to Evaluate a Green Bond

If you are an institutional investor or a retail participant accessing the market via mutual funds, evaluating a green bond requires a dual-lens approach:

Check Issuer Creditworthiness: Review the credit rating (CRISIL, ICRA, CARE) of the specific debt instrument.
Read the Offer Documents: Check the bond's coupon (interest rate) and maturity date. Compare the yield against a non-green bond of the exact same maturity and credit rating.
Verify the Framework: Does the bond align with SEBI regulations or the Climate Bonds Initiative standard?
Look for Third-Party Review: Ensure an independent certifier has provided a "Second Party Opinion" (SPO) confirming the bond meets green criteria.
Post-Issuance Reporting: Commit to tracking the issuer's annual impact reporting to ensure funds were deployed as promised.

Greenwashing in Sustainable Finance

Greenwashing occurs when an issuer misleads investors about the environmental impact of a bond. For example, a company might issue a green bond to build a "highly efficient" natural gas plant. While more efficient than coal, gas is still a fossil fuel and explicitly excluded from strict green frameworks like India's Sovereign framework.

To combat this, SEBI’s February 2026 guidelines force corporate issuers to use registered independent reviewers. These reviewers must audit the use of proceeds and manage conflicts of interest, ensuring that the environmental disclosures are backed by hard data rather than corporate public relations.

Does a Green Bond Give the Issuer Cheaper Money?

Sometimes, but not automatically.

Investors may accept a slightly lower yield for a green bond than for a similar regular bond from the same issuer. The market calls this pricing difference a "greenium."

In simple terms, if a normal bond would need to offer 7.20 per cent but a comparable green bond can be sold at 7.17 per cent, the issuer's borrowing cost is lower by three basis points (one basis point equals 0.01 percentage point).

The Economic Survey 2025-26 estimates India's Sovereign Green Bond pricing benefit at roughly 0 to 6 basis points and describes it as intermittent.

The Survey identifies several constraints preventing a larger greenium:

Limited trading in the secondary market.
Smaller issue sizes compared with benchmark government securities.
Delays in impact reporting.
Investors holding bonds until maturity rather than actively trading them.

How India Compares With the Global Green Bond Market

Green bonds are now part of a market measured in trillions of dollars globally.

The Climate Bonds Initiative reported that green-labelled bond issuance reached US$653.5 billion globally in 2025.

World Bank market data put cumulative labelled sustainable bond issuance across categories at approximately US$7.52 trillion by June 2026.

India is participating in a global market that has moved beyond the early conceptual stage. The domestic challenge is now about scaling up issuance, deepening secondary market liquidity, and ensuring rigorous post-issuance impact reporting.

News4Bharat POV

There is no single figure that gives a complete picture of India's green bond market. Four numbers are more useful:

₹72,697 crore: Cumulative Sovereign Green Bond issuance recorded from FY2022-23 through FY2025-26.
₹30,274.47 crore: Actual eligible sovereign green expenditure in FY2024-25. It was higher than the ₹21,697.40 crore raised via SGrBs that year, showing green bonds finance only part of eligible government climate spending.
₹18,628.59 crore: News4Bharat's calculation of corporate issues explicitly labelled green in SEBI's ESG debt table as of July 31, 2026. This is separate from sovereign issuance.
0 to 6 basis points: The Economic Survey's estimated range for India's sovereign green pricing benefit, indicating the environmental label does not yet guarantee significantly cheaper borrowing costs.

Together, these figures suggest that India's green bond market has reached a stage where the quality of issuance matters as much as the quantity.

Three areas will determine the next phase:

Issuance needs enough scale and regularity for institutional investors to trade the securities actively.
Allocation and impact reports need to arrive on a predictable, standardized schedule to combat greenwashing.
Municipal and corporate issuance needs to broaden so that the market is not driven solely by sovereign borrowing or a handful of large banking entities.
