Let me start with something we’ve all noticed: sustainability used to be that “nice to have” checkbox. Companies would tick it, issue a report and carry on with business as usual.
Well, those days are done.
In 2026, with India’s Net-Zero 2070 commitment now a reality we’re living with, the “green” side of any balance sheet gets scrutinized same as the profit and loss statement. Under Green Finance Regulators aren’t asking whether your business is sustainable anymore, they want to know how credibly you’re actually transitioning.
For those of us in the CA profession, CFOs, and anyone handling corporate finance, this isn’t some niche trend we can safely ignore. Green finance now sits right at table in the field of capital raising, compliance, assurance, and risk management. So I’ve put my understanding together to serve as your reference, merging what the regulations actually say with what they mean in the real world.
1. The Economics of It All: Why Green Finance Matters (and Where It Can Bite)
Here’s the simple version: Green Finance is capital that goes specifically toward projects with measurable environmental benefits. And as we’re seeing in early 2026, the economic incentives and penalties have gotten a lot more precise.
The good news: why companies are rushing toward green capital
a. Cheaper borrowing: Green bonds in India are currently trading at what’s called a “Greenium”-basically, they cost about 10 to 25 basis points less than regular bonds. Not huge, but definitely worth having.
b. Concessional financing: Government institutions like SIDBI and IREDA have rolled out specialized schemes (the updated 4E Scheme, for instance) with interest rates often 50-100 basis points lower than normal commercial lending especially for MSMEs buying certified energy-efficient equipment.
c. Access to global money: The global impact-investing pool has crossed $100 trillion and that to in 2020-2021 according to Antonmurray report. ESG compliance isn’t a bonus anymore. It can act as the entry ticket for institutional capital.
The not-so-good news: sustainability comes with real strings attached
a. Performance penalties: Sustainability-Linked Bonds (SLBs) now routinely include “coupon step-ups.” Miss your KPI targets (say, a 10% reduction in carbon intensity), and your interest rate automatically jumps. That’s a direct hit to your bottom line.
b. Stranded assets and CBAM: The EU’s Carbon Border Adjustment Mechanism (CBAM) is entering its next phase this year. High-emission assets risk becoming “stranded”-meaning they either lose their value or become too expensive to run because of export penalties.
2. Taxonomies: Why “Green” Means Different Things Depending on Where You Are
Think of a taxonomy as the rulebook that defines what counts as “green”. Without following that the claims of sustainability are just claims.
The EU way: strict and science-based
The EU Taxonomy operates on a “Do No Significant Harm” (DNSH) principle. Your project has to contribute positively to at least one environmental objective without meaningfully harming any of the others. So, if your renewable energy project damages local biodiversity? It will fail the test entirely.
India’s way: pragmatic and realistic
India’s Draft Climate Finance Taxonomy takes a different approach. It includes a “Transition” category, which allows funding to flow into hard-to-abate sectors like steel, cement, and heavy chemicals-as long as the money is being used for real, measurable efficiency improvements.
In other words, India is funding the journey from brown to light green, rather than demanding everyone turn perfectly green overnight.
3. Greenwashing: Why SEBI Had to Step In During 2025
As green capital became cheaper and easier to access, the temptation to exaggerate sustainability credentials grew. Fast.
Greenwashing essentially means lying or stretching the truth about your environmental credentials to attract funding which became enough of a problem that SEBI significantly tightened the rules under its 2025 ESG Debt Framework.
Here’s what changed:
a. Negative externality disclosures: You now have to explicitly disclose any adverse environmental impacts from your project. Using excessive groundwater for a solar plant? You have to say so.
b. Investor protection through early redemption: If your security loses its “green” status because of misrepresentation, investors now have a regulatory path to demand early repayment of principal.
The message is clear: ESG misstatements aren’t just reputational risks anymore, they also carry actual financial consequences.
4. The Banking Bottleneck: Why Green Loans Are Still Tough to Get
Despite all the regulatory encouragement, many businesses particularly MSMEs are finding it surprisingly hard to actually access green finance.
The usual friction points:
a. Technical gaps: A lot of bank branches simply don’t have the expertise to evaluate the environmental performance of specialized machinery or processes.
b. Collateral issues: Green equipment often doesn’t have much resale value, so lenders ask for additional collateral.
c. Higher compliance costs: Third-party certifications and audits can add 2–5% to your project costs-which is material when you’re a smaller borrower.
If you’re advising MSMEs on this, managing expectations upfront is absolutely crucial.
5. SEBI’s Expanded Framework for Green and ESG Debt
The June 2025 SEBI circular was a big deal. It moved us from a narrow “green bond only” approach to a much broader ESG debt ecosystem.
What’s new:
a. Formal recognition of ESG-labelled instruments: Social Bonds, Sustainability Bonds, and Sustainability-Linked Bonds are all explicitly covered now.
b. Regulatory alignment: These instruments fall under the SEBI (Issue and Listing of Non-Convertible Securities) Regulations.
c. Strict tracking of fund usage: Issuers have to maintain dedicated sub-accounts, ensuring complete traceability of funds to approved projects.
This has raised the bar significantly on documentation and internal controls.
6. Mandatory Reviews and the “Comply or Explain” Option
SEBI has effectively ended the era of voluntary disclosures.
a. Pre-issuance review: You need an independent reviewer to confirm taxonomy alignment before you can issue anything.
b. Post-issuance verification: Annual audits are required to confirm you actually used the funds as promised.
c. “Comply or Explain” flexibility: Smaller listed entities can temporarily explain non-compliance with certain disclosures-as long as they include a credible roadmap in their Annual Report.
This transition phase is particularly relevant if you’re working with mid-cap companies.
7. BRSR in 2026: No Longer a Tick-Box Exercise
The Business Responsibility and Sustainability Report (BRSR) has gone from being a “soft disclosure” to a high-stakes compliance document. The current reporting cycle is all about Reasonable Assurance.
What you need to know for 2026 (FY 2025-26):
a. BRSR Core Assurance: As per circular issued on July 12, 2023 (SEBI/HO/CFD/CFD-SEC-2/P/CIR/2023/122) by SEBI, the top 500 listed entities now need to get reasonable assurance (which is a higher bar than “limited assurance”) over nine core KPIs in FY 2025-26. This mandate expands to the top 1,000 entities starting next financial year (FY 2026-27).
b. Value Chain Disclosures: Right now, the top 250 listed entities are expected to report ESG data for their entire value chain (upstream and downstream) on a voluntary/comply-or-explain basis. From FY 2026-27 onwards, this becomes a mandatory “assurance” requirement.
c. The MSME ripple effect: Even unlisted MSMEs are feeling the pressure now. As the top 250 companies gear up for next year’s mandatory value chain reporting, they’re already asking their suppliers for GHG and water-usage data to build their baselines.
Wrapping Up: The CA as a Green Navigator
Our role as Chartered Accountants has shifted-quietly, but fundamentally.
We’re not just about tax optimization and statutory compliance anymore. Today, we’re green navigators, helping businesses lower their cost of capital, manage transition risks, and stay credible in an increasingly strict regulatory environment.
The professionals who understand green finance early won’t just protect their clients-they’ll actively shape the next phase of Indian corporate finance.
And honestly? That’s a pretty exciting place to be.
