Green, Social and Sustainability Bonds: Where the Money Goes
A bond is a loan from investors to an issuer. The issuer pays interest and repays the amount due. A green, social or sustainability label tells investors how the borrowed money should be used.

Timeline: Framework to Rulebook
2022: India released its Sovereign Green Bond Framework.
January 2023: The first sovereign green bonds were sold.
June 2025: The Securities and Exchange Board of India (SEBI) set rules for listed social, sustainability and sustainability-linked bonds.
Sovereign means issued by a national government. The word does not say whether the bond is green.
The Reserve Bank of India (RBI) runs government bond auctions. Ministries choose eligible public spending under the green framework.

QUICK CHECK 1 OF 6 · TRUE OR FALSE
Did India sell its first sovereign green bonds after it released the 2022 framework?
Yes. The first auction was in January 2023.
Show answer
True. Yes. The first auction was in January 2023.
Must Know: Three Scopes and Four Shared Rules
1. First, what does a bond promise?
Suppose a city borrows ₹100 crore by selling bonds. It promises interest, called a coupon, and later repayment.
The project may help people, but the bond can still default. Repayment risk mainly depends on the issuer’s ability to pay.
2. Then ask where the money goes
| Type | Use of money | Example |
|---|---|---|
| Green | Eligible environmental work | Clean transport |
| Social | Eligible social work | Affordable housing |
| Sustainability | Both green and social work | Clean buses and low-cost housing |
| Sustainability-linked | General spending can be allowed | Interest changes if a measured target is missed |
The first three are use-of-proceeds bonds. This means the issuer sets aside money for named types of work.
A sustainability-linked bond uses a different test. Its financial terms depend on a target, such as lower emissions.
Worked example. A green bond is like a loan with a rule: “this money must go toward solar panels.” A sustainability-linked bond is different: the company can spend the money on anything, but it promises to cut its carbon emissions by, say, 30% in five years. If it misses that target, its interest rate goes up as a penalty. One controls where the cash goes. The other controls what the company must achieve, no matter where the cash goes.

Does sovereign mean that a bond must be green?
No. Sovereign names the national-government issuer, not the use of money.
Show answer
False. No. Sovereign names the national-government issuer, not the use of money.
Good to Know: What India’s Green Bonds Actually Fund
1. Four steps protect the label
- Use: Say which projects can get the money.
- Choose: Explain how projects are checked and selected.
- Track: Keep a record of where the proceeds go.
- Report: Publish allocation and, where possible, results.
These are the four main parts of ICMA’s green and social bond principles. An outside review can add trust.
Worked example. Picture a state government issuing a ₹500 crore green bond for solar power. First, it names eligible projects: solar farms only, not roads (use). Next, it explains how it picked three specific solar sites (choose). Then it keeps a running ledger showing exactly how much of the ₹500 crore has actually been spent on each site (track). Finally, it publishes a yearly report stating how many megawatts of solar capacity the bond money built (report). Skip any one step, and outside investors have no way to verify the “green” claim.
For example, a metro project may qualify as clean transport. The issuer should report what share of bond money it received.
A claim about avoided emissions needs a clear method. Building a station alone does not prove every climate benefit claimed.
India’s sovereign framework lists eligible areas. It includes clean transport, renewable energy, water work and pollution control.
It generally excludes direct fossil-fuel spending. Read the framework for its narrow public-transport exception on cleaner gas.

QUICK CHECK 3 OF 6 · TRUE OR FALSE
Does a greenium mean that green bonds always pay a higher yield than similar ordinary bonds?
No. A greenium means the green bond may have a lower yield. It is not guaranteed.
Show answer
False. No. A greenium means the green bond may have a lower yield. It is not guaranteed.
Great to Know: Sovereign Dominance and the RBI’s Nerve
1. What does the bond cost?
A bond’s yield is the return an investor expects at its price. Price and yield move in opposite directions.
A greenium is a lower yield on a green bond than on a similar ordinary bond. It can change between auctions.
A green label does not guarantee cheap borrowing. Investors still judge risk, maturity, supply and market interest rates.
Worked example. Say an ordinary 10-year government bond yields 7.10%. A green bond with the same maturity, sold the same week, might yield only 7.05%, a 5-basis-point greenium. That gap means the government pays slightly less interest on the green bond, because enough investors want it specifically for its green label. If demand for green bonds is weak that week, the greenium can shrink to zero or even flip the other way.
The RBI can reject bids at a government auction. Many bids do not mean the government must accept their prices.
2. What can go wrong?
- Greenwashing: A label promises more than the projects deliver.
- Refinancing: Money pays for old work, so new benefits may be small.
- Double counting: Two claims take credit for the same result.
- Weak data: Reports omit the method, baseline or real impact.
External review and honest reporting help, but they cannot remove default risk.
Worked example. Suppose a company issues a green bond, but instead of building a new solar plant, it uses the money to pay off an old loan it took out for that same solar plant five years ago. Technically the money touched a green project. Practically, no new solar capacity got built because of this bond, that’s refinancing risk. If a second company then also claims credit for those same emission cuts in its own report, that’s double counting: two organisations claiming the same environmental win.

Think it through. Why would the RBI cancel a green bond auction in June 2025 even though bids came in at more than double the amount on offer?
Show the explanation
Strong demand in quantity doesn’t mean the price was right. The bid yields were higher than the RBI wanted to accept, so it walked away rather than borrow at a worse rate than intended.
Previous Year Question
A Central Armed Police Forces (CAPF) 2025 question asked which Union Budget announced sovereign green bonds.
Answer: 2022–23. The framework came in November 2022. The first auction followed in January 2023.
QUICK CHECK 4 OF 6 · TRUE OR FALSE
Did the 2022–23 Union Budget announce sovereign green bonds?
Yes. The framework and first auction followed later.
Show answer
True. Yes. The framework and first auction followed later.
Current Affairs
1. India’s rules now cover more labels
SEBI issued its 2025 framework for listed social, sustainability and sustainability-linked debt. Green debt already had separate rules.
The central government issues sovereign green bonds under its own framework. A company must follow the rules for its listed debt.
India publishes allocation reports for its sovereign bonds. Check the report year before quoting a project or a total.
Market prices also change. The Institute for Energy Economics and Financial Analysis and Business Standard describe different auctions.
Those reports are dated examples, not a fixed greenium for every bond.
