All About Green Bonds.
A Regular Corporate Bond with a Conscience, and Exactly the Same Risk to Your Money.
Published as on 9 July 2026
A green bond from an Indian company or PSU is an ordinary corporate bond carrying one extra promise: the borrowed money must fund only environmentally beneficial projects, solar plants, wind farms, clean transport, pollution control. That promise buys you accountability and annual reporting. It buys you nothing on safety. The green label tells you where your money goes, not how likely you are to get it back. Returns still come from the issuer's credit, the coupon and the tenor; the celebrated "greenium" is mostly a myth in India. This is a guide to what corporate and PSU green bonds are, how they are taxed, what can go wrong, and how to evaluate one exactly as you would any bond.

Executive Summary · 7 Findings
A corporate or PSU green bond is a plain bond with a spending constraint. You lend, the issuer pays a coupon and repays at maturity, and the money must be spent on green projects. The label changes accountability, not economics: same coupon, same credit risk, same tax.
This article covers what a green bond is and how the use-of-proceeds mechanics work, where it fits and the greenium myth, the risks (credit, rate, liquidity and greenwashing), how it is taxed, and how to evaluate one with the identical checklist you would use for any bond.
Key Findings
A green bond is a regular corporate bond with a use-of-proceeds label.
When NTPC or Tata Power issues a green bond, you lend money on ordinary terms, a coupon, a tenor, repayment at maturity. The only legal difference is that the proceeds must fund eligible green projects, and the issuer must ring-fence, report and get them verified.
The green label tells you where the money goes, not how safe you are.
Safety is the issuer's credit quality, its rating, cash flows and coverage, not the colour of the project. A BB-rated private renewable bond is riskier than a AAA PSU bond. The solar farm your money funded is not your collateral; on default you are a general creditor.
Returns come from credit, coupon and tenor, not the green label.
If a AAA PSU issues a regular 7.5% bond and a green 7.5% bond of the same maturity, your return is identical. When the RBI moves rates or an agency downgrades the issuer, both bonds move together. The label is priced into nothing that matters to your yield.
The "greenium" is mostly a myth in India.
Globally some green bonds price slightly inside their peers on ESG demand. In India that discount is minimal or negative: the 2023 sovereign green bond priced only about 9 basis points below comparable G-Secs, and several 2024-25 green auctions received no bids at all. Do not expect a premium for going green.
Taxation is identical to any corporate bond, and offers no green benefit.
Interest is taxed at your slab as Income from Other Sources, with 10% TDS above ₹5,000 of annual bond interest. Listed bonds attract 12.5% LTCG after 12 months; unlisted bonds are always short-term at slab under Section 50AA. No Section 80C, no Section 10(15) exemption.
PSU and private green bonds differ by issuer, not by impact.
PSU green bonds (NTPC, Power Finance Corporation, IREDA, IRFC) are usually AAA/AA+ with implicit sovereign comfort and yields around 7-7.5%. Private green bonds span AAA to below investment grade and must be judged company by company. The environmental label is the same on both.
Evaluate a green bond exactly as you would any bond, then verify the green claims.
Rating, yield versus G-Secs, tenor, liquidity, do the financial homework first. Only then check that eligible projects are defined, a credible verifier is appointed, and the framework follows SEBI or ICMA rules. Never raise your corporate-bond allocation just because a bond is green.

The Opening · Page 3
The Opening
A green bond from an Indian company or PSU is, at heart, an ordinary corporate bond with a spending constraint bolted on. When Tata Power or NTPC issues one, they are borrowing exactly as they would through any other bond: you lend, say, ₹10 lakh, they promise 8% a year for five years, and they return your ₹10 lakh at maturity. Nothing about that cash flow is unusual.
The single difference is a legal commitment on how the money is used. The issuer must spend those proceeds only on environmental projects, renewable energy, pollution control, electric-vehicle infrastructure, water treatment, energy-efficient buildings. Think of lending a friend ₹5 lakh on the condition they use it only for rooftop solar: they still owe you the same money on the same terms, but the label ensures accountability about where it lands.
Under SEBI's green debt securities framework, first set in 2017 and substantially revised in 2023 with further refinement through 2025-26, issuers must define which projects qualify, ring-fence the proceeds in tracked accounts, report annually on allocation, and obtain independent third-party verification of both the framework and the actual spending. That reporting is the whole of what you get extra. It is not a safety feature.
"Your friend owes you the same money whether they buy solar panels or furniture. The green label does not change the debt, it only tells you the furniture was never an option."
The Structural Difference
What a green bond is not: it is not safer than the issuer's other debt (credit risk is identical), it is not a higher-return instrument (the greenium is a myth here), and it is not a tax-advantaged product (it is taxed like any corporate bond). It is a regular bond that happens to fund something you may care about, judged on the same numbers as everything else in your fixed-income sleeve.

Part I
What It Is and How It Works
A plain corporate bond, the use-of-proceeds constraint, and the reporting that is the only real difference.
Part I: What It Is and How It Works · Page 4
The Mechanics of a Green Bond
Financially, a green bond behaves like any other corporate bond. It has an issuer, a coupon, a tenor and a maturity date. You buy it in the primary issue or the secondary market, hold it in your demat account, receive periodic interest, and get your principal back at maturity. If NTPC issues a regular 7.5% five-year bond and a green 7.5% five-year bond side by side, the two are financial twins.
The one structural addition is the use-of-proceeds commitment. The issuer legally undertakes to spend the money only on eligible green projects and to prove it. Under SEBI's rules the issuer must deposit proceeds in separate tracked accounts, avoid mixing them with general corporate funds, and disclose, project by project, where the money went.
The Extra You Get: Accountability
Allocation reports: Issuers must publish annual reports showing exactly which projects received proceeds, for instance, ₹400 crore to Rajasthan solar, ₹350 crore to Tamil Nadu wind, ₹250 crore to rooftop-solar financing across states.
Independent verification: A third-party reviewer, a rating agency or specialist ESG firm, certifies that the framework is credible, that proceeds went where promised, and that impact is being measured. Regular corporate bonds carry no such project-level transparency.
"The reporting is real and useful. But it is transparency about a spend, not protection on a loan. A perfectly documented green bond from a weak issuer is still a weak bond."
The Reporting Perimeter
The SEBI Framework
SEBI first formalised a green debt securities framework in 2017, then substantially rebuilt it in 2023 and refined it through 2025-26. The current rules impose four disciplines on every corporate green bond issuer.
Define, Track, Report, Verify
Issuers must clearly define which projects qualify as green, track proceeds in separate accounts, report annually on allocation, and obtain independent third-party verification of both the framework and the actual spending.
The 2023 & 2025-26 Strengthening
The 2023 overhaul made third-party verification mandatory and reporting stricter, alongside a "Dos and Don'ts" circular on greenwashing. Enhanced BRSR Core requirements from 2025 further tightened disclosure for listed entities issuing ESG debt.
How You Hold It
Green bonds are held like any other bond, in your demat account, whether bought in a public issue, on the exchange, or through a SEBI-registered online bond platform. Coupons are credited to your bank account; principal returns at maturity. There is no separate custody, registry or process for the green label.
| Feature | Green Bond | Regular Bond |
|---|---|---|
| Use of proceeds | Green projects only | General purpose |
| Reporting | Annual + verified | None specific |
| Coupon & repayment | Issuer terms | Issuer terms |

Where It Fits and Returns
The portfolio slot, what actually drives your return, the greenium myth, and PSU versus private.
Part II: Where It Fits and Returns · Page 6
Where It Belongs
A green bond is not a separate asset class. It sits inside your debt allocation, under corporate bonds, as a thematic subset, exactly where a regular corporate bond of the same issuer and rating would sit. First decide debt versus equity; then, within debt, how much corporate-bond risk you want versus safer G-Secs; only then, within corporate bonds, whether you want some allocation directed to green projects.
What actually drives your return: the coupon (set by the issuer's rating, prevailing rates and tenor at issue), and, if you sell before maturity, capital gains or losses as rates and ratings move. AAA PSUs might yield around 7-7.5%; lower-rated issuers 9-10%. The 10-year G-Sec benchmark sat near 6.67-6.68% in early 2026, the risk-free anchor everything else prices off. None of these levers has anything to do with the green label.
PSU vs Private
The meaningful distinction is not green versus non-green, it is who issues. Ownership drives credit quality, and credit quality drives your risk and yield.
PSU Green Bonds
NTPC, Power Finance Corporation, IREDA, IRFC and peers: government-majority-owned, usually AAA or AA+, with implicit (not legal) sovereign comfort and historically low default rates. Highly-rated PSUs often price around 7-7.5%, reflecting perceived safety.
Private Corporate Green Bonds
Tata Power, ReNew and others span AAA to below investment grade. Safety depends entirely on the company's balance sheet, so each must be judged individually. Yields run from about 7.5% for the strongest names to 10%+ for weaker ones, purely a credit spread, not a green spread.
Who It Suits
Good Fit
Investors who already want high-grade corporate-bond exposure and would value the transparency, or who wish to direct capital to environmental projects without sacrificing financial discipline.
Poor Fit
Investors expecting extra yield from the greenium, treating green as a safety upgrade, or over-allocating to corporate bonds simply because a bond "feels good".
Part III
The Risks
The same credit, interest-rate and liquidity risk as the issuer's regular bonds, plus greenwashing or label risk.
Part III: The Risks · Page 8
What Can Go Wrong
Credit / default risk
If the issuer runs into distress, your green bond can default like any of its bonds. The solar project you funded is not pledged to you; you rank as a general creditor. Check the rating (AAA highest, D default), debt-to-equity, interest coverage and repayment record, the label protects none of this.
Interest-rate / duration risk
When the RBI raises rates, bond prices fall, and green bonds fall exactly like regular ones of the same tenor. Your coupon keeps paying, but the market value drops if you must sell early. Longer tenors carry more of this risk; match maturity to your horizon.
Liquidity risk
Some corporate green bonds, especially smaller or privately placed issues, trade thinly. Selling before maturity can mean few buyers, wider bid-ask spreads and slower settlement. Large PSU issues (PFC, NTPC, IRFC) are more liquid; small private issues may effectively be hold-to-maturity.
Greenwashing / label risk
The risk unique to green bonds: proceeds funding marginal projects dressed up as green, refinancing existing debt without additionality, vague reporting, or no real verification. SEBI's 2023 and 2025-26 rules have cut this sharply, but you should still read the offer document and prefer proven issuers.
Sector-concentration risk
Many green bonds fund renewable-energy issuers exposed to DISCOM payment delays, policy and subsidy changes, and high leverage. Do not concentrate more than 20-30% of your corporate-bond sleeve in the renewable sector, however much you like the theme.
The Label Trap
The most common mistake is treating "green" as "safe". A green bond from a financially weak company is riskier than a regular bond from a strong one. Even flawless allocation reporting does not remove one rupee of financial risk.
Red Flags to Watch
Vague project descriptions ("sustainable business development"), no named third-party verifier, missing allocation reports beyond 18 months, or projects with questionable environmental benefit. Any of these warrants a hard second look.
Part IV
Taxation in India
Interest at slab, listed versus unlisted capital gains, and the green label's zero tax advantage.
Part IV: Taxation in India · Page 10
Interest and TDS
There is no special tax treatment for corporate or PSU green bonds. They are taxed exactly like regular corporate bonds, and the green label provides zero advantage.
Interest Income (Coupon)
Fully taxable as Income from Other Sources, added to your total income and taxed at your marginal slab rate. Under the FY 2025-26 new regime, slabs run from nil up to ₹4 lakh (after ₹75,000 standard deduction) to 30% above ₹24 lakh.
TDS at 10%
If your annual interest from bonds exceeds ₹5,000, the issuer deducts 10% TDS. This is advance credit, if your actual liability is lower, you claim a refund when filing your return.
Worked example: On ₹10 lakh in an 8% green bond, annual interest is ₹80,000, with ₹8,000 TDS, so you receive ₹72,000. If your income puts you in the 20% slab, the tax on that interest is ₹16,000; ₹8,000 already paid via TDS leaves ₹8,000 due at filing.
Capital Gains on Sale
If you sell before maturity, the treatment depends on whether the bond is listed, and how long you held it.
Listed Green Bonds (BSE/NSE)
Held 12 months or more: Long-Term Capital Gains at 12.5% flat, with no indexation post 23 July 2024. Held under 12 months: Short-Term, taxed at your slab rate.
Unlisted Green Bonds
Under Section 50AA (Budget 2024), always treated as short-term regardless of holding period, and taxed at your slab rate. There is no long-term benefit on privately placed, unlisted paper.
Worked example: You buy a listed PFC green bond at ₹98 and sell at ₹104 after 18 months. The ₹6 gain per unit is long-term at 12.5%, ₹0.75 tax per unit, leaving ₹5.25 net.
| Instrument | Interest | LTCG (>12m) |
|---|---|---|
| Green bond (listed) | Slab | 12.5% |
| Regular bond (listed) | Slab | 12.5% |
| Bank FD | Slab | N/A (interest only) |
| Unlisted bond | Slab | Slab (Sec 50AA) |
Part V
How to Evaluate
The identical checklist you would use for any bond, how the impact actually works, and how much to hold.
Part V: How to Evaluate · Page 12
The Evaluation Checklist
Do the financial homework first, exactly as you would for a regular corporate bond. Verify the green credentials only afterwards, and never let them override a financial "no".
Rating and issuer
Prefer AA- or better. AAA/AA+ is institutional-grade; A-band suits moderate risk appetite; below BBB is speculative. Check the issuer's coverage, leverage and repayment history, PSU or private, credit quality decides.
Yield versus the benchmarks
Compare the offered yield with the 10-year G-Sec (~6.67-6.68%), bank FDs of similar tenor, and same-rated bonds from other issuers. The spread over G-Secs should compensate for credit risk; the green label should add nothing.
Tenor and liquidity
Match maturity to your horizon; longer tenors carry more rate risk. Confirm the bond is listed, prefer larger issues (₹500 crore-plus) for tighter spreads, and assume small private issues may be hold-to-maturity.
Then verify the green claims
Are eligible projects clearly defined and SEBI-aligned? Is a credible third-party verifier (CRISIL, ICRA, Care, Sustainalytics) appointed? Does the framework reference SEBI rules or the ICMA Green Bond Principles? Has the issuer reported on time before?
How Impact Works & Sizing
You direct capital; you do not run the project. The issuer raises the money, ring-fences it, spends it on eligible assets (panels, land, grid, commissioning), then reports allocation and impact, verified independently. As a bondholder you are a lender entitled to interest and principal, not a co-owner of the asset, not entitled to project profits, and not protected on default just because the money did good.
Your Real Impact
Indirect but genuine: you make green infrastructure financeable, you create demand that encourages more issuance, and you receive transparency about where the money went, which a plain bond never gives you.
How Much to Hold
Green bonds are a slice within your corporate-bond allocation, not an addition to it. Conservative investors might keep 0-5% of the debt sleeve in green bonds; moderate investors 5-15%; higher-risk investors up to 10-25%, always staying inside the debt category. The cardinal rule: do not raise your total corporate-bond allocation just because the bonds are green.
| Profile | Corp Bonds (of debt) | Green (of corp) |
|---|---|---|
| Conservative | 10-15% | 0-5% |
| Moderate | 20-35% | 5-15% |
| Higher-risk | 30-50% | 10-25% |
Diversify
Spread across issuers, mix PSUs with strong private corporates, and combine green with regular bonds. Never pour the whole corporate-bond sleeve into a single green bond because you like the theme.
Part VI
The Verdict
How to treat a green bond in a real plan, and the one rule that keeps you honest.
Part VI: The Verdict · Page 14
The Assessment
Treat a corporate or PSU green bond as what it is: a regular corporate bond that happens to fund green projects and comes with better disclosure. It belongs in your debt sleeve, under corporate bonds, judged on the same numbers, rating, yield, tenor, liquidity, as any other bond. The green label is a feature, not a financial upgrade.
Do not expect a greenium; in India it barely exists. Do not expect a safety upgrade; credit risk is the issuer's, not the project's. Do not expect a tax break; interest is taxed at slab and there is no 80C or 10(15) shelter. What you can expect is transparency about where your money goes, and, if the issuer is high-grade, a perfectly respectable fixed-income holding.
"Buy the bond you would buy without the green label, then let the label be the reason you chose it over an equally good plain one. Never let it be the reason you overpaid, over-allocated, or ignored a weak credit."
The Discipline
For most investors: if you already want high-grade corporate-bond exposure, a well-verified PSU or strong-private green bond of the same rating and yield is a sound choice with a conscience attached. The one rule: the financial decision comes first, always.
ADWIZR · July 2026
How to Decide
Do the credit work first
Rating AA- or better, healthy coverage and leverage, clean repayment record. If the credit fails, the green story is irrelevant.
Price the yield honestly
Compare against G-Secs, FDs and same-rated peers. Expect no greenium; if you are asked to accept a lower yield for the label, decline.
Verify the green credentials
Clearly defined eligible projects, a named credible verifier, SEBI/ICMA-aligned framework, and a track record of timely allocation reports.
Size it within, not on top of, your allocation
Keep green bonds a slice of your corporate-bond sleeve, diversified across issuers. Do not expand corporate-bond risk just because it is green.
The Bottom Line
A corporate or PSU green bond gives you a plain bond's economics with transparency about where the money goes. The green label tells you the destination, not the safety, of your investment. Evaluate it like any bond, rating, yield, tenor, liquidity, expect no greenium and no tax break, keep it a disciplined slice of your corporate-bond allocation, and let "green" be the tie-breaker, never the thesis.

Key Terms & Definitions
Green Bond
A debt security identical in form to a regular corporate bond, carrying one legal constraint: the proceeds must fund only eligible environmental projects such as renewable energy, clean transport, pollution control or energy efficiency. The green feature governs the use of money, not the risk or return to the investor.
Use of Proceeds
The SEBI requirement that a green bond's raised funds be ring-fenced in separate tracked accounts and spent only on defined green projects, with no mixing into general corporate funds. It is the single structural feature that distinguishes a green bond from a plain bond.
Greenium
The green premium: a slightly lower yield some green bonds command because of ESG investor demand. Meaningful in parts of Europe (10-30 bps), it is minimal or negative in India, roughly 9 bps on the 2023 sovereign green bond, and some 2024-25 green auctions drew no bids at all.
Greenwashing
Presenting a bond as environmentally beneficial when it is not, via loose project definitions, refinancing without additionality, vague impact claims, or missing verification. SEBI's 2023 and 2025-26 rules mandate verification and disclosure to curb it, but investor vigilance remains necessary.
Third-Party Verification
The independent review, by agencies such as CRISIL, ICRA, Care Ratings or Sustainalytics, certifying that a green bond's framework is credible, its proceeds went where promised, and its impact is measured. SEBI requires it before issuance and for annual allocation reporting.
PSU Bond
A bond issued by a Public Sector Undertaking, a company where the government owns 51% or more (NTPC, Power Finance Corporation, IREDA, IRFC). Usually rated AAA or AA+, with implicit but not legal sovereign comfort, and often priced around 7-7.5% for the strongest names.
Section 50AA
The Income Tax provision (Budget 2024) under which gains on unlisted bonds and certain debt instruments are always treated as short-term and taxed at the investor's slab rate, regardless of holding period, removing any long-term benefit on unlisted paper.
ICMA Green Bond Principles
Voluntary international guidelines from the International Capital Market Association covering use of proceeds, project evaluation, management of proceeds and reporting. Credible Indian issuers reference them alongside SEBI's green debt framework to signal alignment with global best practice.
