The global ESG debate has grown louder and more fractious. But for Indian businesses, the more consequential question is quieter and closer to home: when your ESG disclosures face independent scrutiny for the first time, will they hold?
6 months into 2026; and the news that made to the top were quite interesting. The United States has continued its federal retreat from ESG commitments, with several institutional investors quietly recalibrating their public positions under political pressure. Europe, which set the pace for mandatory sustainability reporting, is itself navigating recalibration – the proposed Omnibus package has sought to scale back CSRD scope and timelines, reflecting pushback from industry on the pace of implementation. That conclusion would be a strategic error for any Indian business leader making it.
India has not followed the global noise. It has followed its own trajectory – methodically, incrementally, and with increasing rigour. The BRSR framework, which we discussed when the ESG wave first reached Indian boardrooms, established the reporting foundation. What has happened since is more significant: India has moved from asking companies to report to asking them to prove. That is a fundamentally different demand, and it is the demand that is live for Indian businesses right now.
The shift from reporting to reckoning
There is a distinction worth making clearly, because it shapes everything that follows. The Business Responsibility and Sustainability Report or BRSR, is India’s comprehensive ESG disclosure framework, mandatory for the top 1,000 listed companies. It covers environmental performance, workforce practices, governance, and community engagement across structured disclosures. It is a substantial document, and producing it well requires real effort.
BRSR Core, introduced by SEBI, is now rolled out across India’s listed universe in phases. It is a defined subset of Key Performance Indicators, which requires independent assessment or assurance. Not narrative. Not management representation. Independent, third-party verification.
The phased rollout means that by FY2025-26, India’s top 500 listed companies were in mandatory assessment scope. The top 1,000 follow in FY2026-27. For companies in the 251 to 500 band, this is not a future planning item. It is the current reporting cycle. And in December 2024, SEBI went further still – publishing Industry Standards on Reporting of BRSR Core, developed by the Industry Standards Forum in collaboration with ASSOCHAM, FICCI, and CII, to standardise methodology and calculation approaches across companies. The bar is not just being raised. It is being defined with increasing precision.
The question this creates for leadership is not “do we comply?”. It is “what happens when a qualified, independent assessor applies that bar to our numbers?”
What the reckoning actually looks like
Most companies that have gone through their first BRSR Core assessment cycle report a version of the same experience. The disclosure was not the problem; instead the problem was behind the numbers – who owned each metric, how it was calculated, what the source evidence was, and whether the methodology was consistent across sites and across quarters.
The gaps that surface are rarely exotic. They are structural. GHG emission calculations that rely on factors applied inconsistently across facilities. Water consumption figures that aggregate site-level data through a process that exists in a spreadsheet owned by one person. Wage data that is available in payroll systems but has never been extracted in a form that maps cleanly onto the BRSR Core KPI definition. Waste figures that exist for some locations and are estimated for others, with the estimation methodology undocumented.
None of these gaps are unfixable. But none of them are fixable in the week before an assessor arrives. They require the kind of deliberate infrastructure work – defined ownership, documented methodology, controlled data flows, evidence trails – that takes months to build properly. Companies that have done this work find that the assessment process is straightforward. Companies that have not find that the gap between what they want to report and what they can credibly demonstrate is wider than they anticipated.
The March 2025 SEBI circular that recalibrated value chain disclosure timelines – moving mandatory value chain ESG disclosures to FY2026-27 and easing the scope to focus on partners contributing at least 2% of purchases and sales – has given companies additional runway on the supply chain dimension. That runway is an opportunity to build the supplier engagement infrastructure properly, not a reason to defer it entirely.
The MNC Dimension: Multiple Frameworks, One India Operation
For multinationals with significant India operations, the BRSR Core assessment requirement arrives alongside ESG reporting obligations flowing from their global parent. These obligations differ by headquarter jurisdiction — European parents navigate CSRD timelines and European Sustainability Reporting Standards; US-listed parents manage SEC-aligned investor expectations and state-level mandates from California and New York; Japanese and Korean subsidiaries operate under Tokyo Stock Exchange and K-ESG guidelines; Singapore-headquartered groups work within MAS sustainability reporting requirements.
The metrics do not map cleanly across frameworks. The timelines do not align. And the documentation standards — what counts as sufficient evidence, what level of precision is expected in emission factor selection, what disclosure is required about methodology assumptions — vary in ways that matter when assessors and auditors apply them.
The India operations of multinationals are therefore increasingly being asked to serve two disclosure regimes simultaneously while building one data infrastructure. The companies doing this well have stopped treating BRSR Core and global parent reporting as separate compliance workstreams. They have recognised that the underlying requirement — credible, evidenced, consistently calculated ESG data — is the same regardless of which framework is consuming it. One well-built infrastructure serves both. Two parallel processes built to minimum specification serve neither well.
Credibility as a strategic asset
The framing that tends to unlock this for C-Suite leadership is not the compliance frame. It is the credibility frame.
An assured or assessed BRSR Core disclosure is a statement to every stakeholder that matters — investors making allocation decisions, lenders pricing sustainability-linked instruments, procurement counterparties applying supplier ESG criteria, global parents consolidating group disclosures — that the numbers behind the ESG story have been independently examined and found to be defensible. That is a materially different signal from a well-written sustainability narrative that has never been tested.
The organisations building this credibility now are finding that its value compounds. ESG data that is produced through defined, controlled processes and verified by an independent assessor tends to be used differently internally as well — in resource allocation decisions, in supplier conversations, in board risk discussions. The rigour required to make a number assurable also tends to make it useful. These are not separate benefits. They are the same benefit expressed in different directions.
Three questions worth asking before the assessor does
If you are a business leader reflecting on where your organisation stands, three questions cut to the heart of readiness:
- For your most significant BRSR Core KPIs — GHG emissions, water, energy — can you trace the number on your disclosure back to its source data, through each transformation step, with the methodology documented and the assumptions recorded? If that trail requires calling three people and opening four shared drives, it is not assessment-ready.
- Is there a named individual in your organisation who is accountable for each BRSR Core metric — not just responsible for filling in a template, but accountable for the process being robust, the calculation being consistent year on year, and the evidence being available when asked for?
- If your global parent’s ESG reporting team asked tomorrow for the same underlying data in a different format — mapped to TCFD, or ISSB, or their own internal framework — could your India operation produce it without rebuilding the exercise from scratch?
If any of these surfaces uncertainty, the gap is better understood and addressed now than when an assessor’s questions make it visible under time pressure. Avtar ESG works with Indian businesses and MNC India operations across the full journey — from ESG advisory and BRSR reporting support, to assessment readiness, training, and supplier audits.
