If you have filed a BRSR, you have already collected most of the data an ESRS report needs. The mistake is assuming that means the job is mostly done. Mapping BRSR data onto the European standards is the easy part, call it 20% of the effort; the three things ESRS demands that BRSR never asks for, a double-materiality assessment, mandatory Scope 3 where material, and quantified targets with a transition plan, are the other 80%. Treat the crosswalk as a map of where your data goes, not a shortcut to a finished report, and it becomes genuinely useful.
BRSR is SEBI's Indian format; the ESRS are the twelve reporting standards behind the EU's Corporate Sustainability Reporting Directive (CSRD). They overlap heavily on the underlying data, which is why more Indian companies, EU subsidiaries and exporters are asking the same question: can our BRSR data feed an ESRS report? This guide answers it with a cited, topic-level crosswalk, and is honest about where the two diverge.
Key takeaways
- 01BRSR maps topic-for-topic onto the ESRS environmental (E1–E5), social (S1–S4) and governance (G1) standards, so most BRSR data carries across.
- 02The 2026 Omnibus reset narrowed CSRD scope and cut ESRS datapoints by roughly 60–70%, but left the twelve standards and their topics intact, so a topic-level crosswalk still holds.
- 03ESRS adds three things BRSR does not require: a double-materiality assessment, mandatory Scope 3 where material, and quantified targets with a transition plan.
- 04This is a crosswalk, not a CSRD applicability test: whether a company must report under CSRD depends on EU turnover and headcount thresholds.
What the ESRS and CSRD are
The CSRD is the EU law that mandates sustainability reporting; the ESRS are the standards that say what to disclose. There are twelve: two cross-cutting standards (ESRS 1 and ESRS 2, on general requirements and general disclosures), five environmental (E1 Climate change, E2 Pollution, E3 Water and marine resources, E4 Biodiversity and ecosystems, E5 Resource use and circular economy), four social (S1 Own workforce, S2 Workers in the value chain, S3 Affected communities, S4 Consumers and end-users), and one governance (G1 Business conduct). If that structure feels familiar, it is because BRSR's nine principles cover much the same ground, organised differently.
What the 2026 Omnibus reset changed
The EU's Omnibus I directive, in force from 18 March 2026, was a significant simplification. It matters for Indian companies because it changes both who reports and how much.
- Scope narrowed. CSRD now applies to EU undertakings with more than 1,000 employees AND turnover above EUR 450 million, so many smaller entities dropped out of scope.
- Datapoints cut. The revised ESRS reduce mandatory datapoints by roughly 60–70% and delete the voluntary ones, with first application from FY2027 (FY2026 voluntary).
- Value-chain cap. Large reporters cannot demand more from smaller value-chain partners than a lighter voluntary standard (VSME) asks, which limits what Indian suppliers can be pushed to provide.
- Non-EU parents. EFRAG is due to advise on Non-EU Sustainability Reporting Standards (NESRS) by early 2027, the route by which large Indian parent groups may eventually report.
The topics did not change, the volume did
The BRSR-to-ESRS crosswalk
Mapped at the principle level, the granularity at which the data actually transfers. This is an indicative consultant aid drawn from the ESRS Delegated Regulation, not an official SEBI or EFRAG crosswalk.
| BRSR principle | Maps mainly to | What transfers |
|---|---|---|
| P1 Ethics | ESRS G1 + ESRS 2 | Anti-corruption and anti-bribery policy, board oversight, whistleblowing, conflicts of interest |
| P2 Products | ESRS E5 | Sustainable sourcing, recycled inputs, product end-of-life and circularity data (EPR is the Indian instrument) |
| P3 Employee wellbeing | ESRS S1 | Workforce headcount, diversity, health and safety, training, wages, collective bargaining |
| P4 Stakeholder engagement | ESRS 2 | Stakeholder identification and the materiality process (ESRS asks for double materiality) |
| P5 Human rights | ESRS S1 + S2 | Human-rights policy, incidents and grievances; value-chain due diligence feeds S2 |
| P6 Environment | ESRS E1, E2, E3, E5 | Energy, Scope 1/2/3 GHG, water, pollutants, waste and circularity, the richest overlap by far |
| P7 Policy advocacy | ESRS G1 | Trade-association memberships and lobbying positions (G1-5) |
| P8 Inclusive growth | ESRS S3 + S2 | Community impacts and supplier practices (statutory CSR spend is India-specific) |
| P9 Consumer responsibility | ESRS S4 | Consumer grievances, product safety, data privacy and responsible marketing |

Why this matters for Indian companies
BRSR is an Indian obligation, so why should an Indian consultant follow a European standard? Three reasons, and they are getting louder.
- The subsidiary route. An Indian group with a large EU subsidiary can be pulled into CSRD through that subsidiary, and the group's Indian operations have to feed the ESRS report.
- Customers ask. European buyers increasingly want ESRS-aligned data from their suppliers, so an Indian exporter may be asked for E1 emissions or S1 workforce figures whether or not it files CSRD itself.
- The NESRS route. EFRAG is developing Non-EU Sustainability Reporting Standards for large non-EU parents with significant EU turnover, expected to be advised on by early 2027, the mechanism most likely to reach large Indian groups directly.
- Investors. Global investors read ESRS as the baseline, and a company that can show its BRSR data already maps to ESRS signals maturity.
In every one of these, the underlying work is identical: take the data you already collect for BRSR and re-express it in the ESRS structure. The rest of this guide is that map, standard by standard.
Environment: how Principle 6 maps to E1–E5
This is the densest overlap, and the reason a BRSR filing is such a strong ESRS head start. BRSR Principle 6 feeds four of the five environmental standards almost directly.
- E1 Climate change. Your P6 energy consumption and mix, Scope 1 and Scope 2 emissions and GHG intensity map straight to ESRS E1-5 (energy) and E1-6 (gross emissions). ESRS then adds a transition plan (E1-1) and quantified targets (E1-4) that BRSR does not ask for.
- E3 Water and marine resources. P6 water withdrawal, consumption and discharge map to ESRS E3-4, with ESRS additionally flagging withdrawals in water-stressed areas.
- E5 Resource use and circular economy. P6 waste generation and recovery, plus P2 recycled inputs and end-of-life, map to ESRS E5-4 and E5-5.
- E2 Pollution. P6 air emissions other than GHG (NOx, SOx, particulate matter) map to ESRS E2-4.
- E4 Biodiversity and ecosystems. P6 operations in or near ecologically sensitive areas map to ESRS E4-5.
The one environmental gap: mandatory Scope 3
Social: Principles 3, 5, 8 and 9
BRSR's social principles line up cleanly with the four ESRS social standards, which is where a lot of the workforce and community data transfers wholesale.
| BRSR principle | ESRS standard | What carries across |
|---|---|---|
| P3 Employee wellbeing | S1 Own workforce | Headcount, diversity, health & safety, training, wages, collective bargaining |
| P5 Human rights (own ops) | S1 Own workforce | Human-rights policy, incidents, grievances, non-discrimination |
| P5 Human rights (value chain) | S2 Value-chain workers | Supplier human-rights due diligence and assessments |
| P8 Inclusive growth | S3 Affected communities | Community impacts, rehabilitation, local development |
| P9 Consumer responsibility | S4 Consumers & end-users | Product safety, data privacy, responsible marketing, grievances |
The gaps to watch on the social side are double materiality (below) and the depth of value-chain worker data that ESRS S2 expects, which is heavier than BRSR's P5 Leadership indicators.
Governance: Principles 1 and 7
ESRS has a single governance standard, G1 Business conduct, plus the general disclosures in ESRS 2. BRSR Principle 1 (anti-corruption policy, board oversight, whistleblowing, conflicts of interest) maps to G1-1 and G1-3, and the board-oversight elements to ESRS 2 GOV-1 and GOV-2. Principle 7 (trade-association memberships and policy advocacy) maps to G1-5 on lobbying and political influence, an area European investors increasingly test for consistency with a company's stated climate position.
What ESRS asks for that BRSR does not
The crosswalk saves you the data-collection work, not the extra analysis. Three ESRS requirements have no BRSR equivalent, and this is where the real effort sits:
- 01Double materiality. ESRS 2 requires you to assess both how sustainability issues affect the company (financial materiality) and how the company affects people and planet (impact materiality). BRSR's materiality is lighter and single-lens.
- 02Mandatory Scope 3. ESRS E1 requires Scope 3 emissions where material; BRSR keeps Scope 3 (P6-L2) a voluntary Leadership indicator.
- 03Targets and transition plan. ESRS E1 expects quantified climate targets and a transition plan aligned to 1.5°C; BRSR asks what you do, not where you are headed.
Collect once, report to both
The practical takeaway is the one Saaksh is built around: collect the underlying data once, then map it into each framework's structure. A BRSR filing is a strong ESRS starting point, but treat the crosswalk as a map of where your data goes, not a promise that the ESRS report is done.
