BRSR value-chain rules: what suppliers must report from FY2026–27

If a large listed customer has asked you for ESG or emissions data, it's almost certainly because of SEBI's BRSR value-chain disclosures. Here's what that means for you as a supplier — in plain English.

What is BRSR, briefly

The Business Responsibility and Sustainability Report (BRSR) is the ESG disclosure that India's market regulator, SEBI, requires from the country's largest listed companies. It replaced the older Business Responsibility Report and has been mandatory for the top 1,000 listed companies by market capitalisation since FY2022–23. A tighter, assured subset called BRSR Core sits inside it.

The part that affects you: the value chain

BRSR doesn't stop at the listed company's own walls. It asks them to report on their value chain — their significant suppliers and customers. In practice, "significant" is defined broadly as partners making up a meaningful share of purchases or sales (commonly framed as those accounting for ~2% or more of purchases/sales, or together covering the bulk of value).

That means if you're a meaningful supplier to a large listed company, their reporting obligation becomes your data request.

The timeline (and an honest caveat)

• Up to FY2025–26: value-chain ESG disclosure has been largely voluntary for the reporting company.
• From FY2026–27: the expectation tightens — value-chain disclosures, with assurance, move toward mandatory for the larger reporting companies, who will in turn need verified data from significant suppliers.

Honest caveat: SEBI has adjusted these timelines before (it previously deferred value-chain rules). Treat the direction as certain and the exact date as moveable — but note that EU CSRD demand on Indian exporters is already live now.

What they'll typically ask you for

• Energy & emissions: electricity use and fuel use → your Scope 1 and Scope 2 emissions.
• Social basics: headcount and gender split, minimum-wage compliance, safety and anti-harassment policies, no child/forced labour.
• Governance: code of conduct, a named contact, basic company details.

How to prepare without overspending

You do not need an enterprise ESG platform — those are built for the company asking you. You need: (1) a one-page evidence folder of your annual numbers, (2) your emissions calculated with India-correct factors, and (3) honest answers on policies, with a dated plan for any gaps.
