Everything Indian listed companies need to know about SEBI's mandatory ESG disclosure framework — BRSR format, principles, deadlines, BRSR Core, and how to file.
BRSR (Business Responsibility and Sustainability Reporting) is India's mandatory ESG disclosure framework, introduced by the Securities and Exchange Board of India (SEBI). It requires the top 1,000 listed companies by market capitalisation to report on their environmental, social, and governance performance annually.
BRSR stands for Business Responsibility and Sustainability Reporting. It is a comprehensive ESG (Environmental, Social, and Governance) disclosure format mandated by SEBI through its circular SEBI/HO/CFD/CMD-2/P/CIR/2021/562 dated 10 May 2021.
The BRSR framework replaced the earlier Business Responsibility Report (BRR) and requires listed entities to disclose quantitative, comparable data on sustainability parameters. Unlike voluntary sustainability reports, BRSR follows a standardised format that enables comparison across companies and sectors.
Key characteristics of BRSR:
India's ESG disclosure journey spans over a decade:
BRSR filing is mandatory for the top 1,000 listed entities by market capitalisation on BSE and NSE. This is determined based on market capitalisation as on 31 March of the preceding financial year.
The filing must be submitted as part of the company's Annual Report. Companies outside the top 1,000 may file BRSR voluntarily.
BRSR Core assurance follows a phased timeline:
The BRSR report is structured in three sections with a total of approximately 216 disclosure questions:
Company details, products/services, operations, employees, CSR details, and transparency/compliance information. This section establishes the reporting boundary and entity profile.
Policy and governance disclosures covering all 9 National Guidelines on Responsible Business Conduct (NGRBC) principles. This covers whether the company has policies, governance structures, and processes for each principle.
Detailed performance indicators for each of the 9 principles, split into Essential Indicators (mandatory) and Leadership Indicators (voluntary but increasingly expected).
BRSR is built on the National Guidelines on Responsible Business Conduct (NGRBC), which define 9 principles:
BRSR Core is a subset of the full BRSR framework, introduced by SEBI in July 2023 through circular SEBI/HO/CFD/CFD-SEC-2/P/CIR/2023/122. It identifies key ESG indicators that must undergo independent assurance.
BRSR Core was designed to make assurance practical and focused. Instead of requiring assurance of the entire 216-question BRSR, BRSR Core identifies approximately 9 key indicators across environment, social, and governance dimensions.
The BRSR Core KPIs that require assurance include:
BRSR Core assurance must be conducted by an independent assurance provider. Key requirements:

BRSR stands for Business Responsibility and Sustainability Reporting. It is India's mandatory ESG disclosure framework introduced by SEBI for the top 1,000 listed companies by market capitalisation.
BRSR is mandatory for the top 1,000 listed companies by market capitalisation on BSE and NSE. Unlisted companies, SMEs, and companies outside the top 1,000 are not required to file BRSR but may do so voluntarily.
BRSR is the complete ESG disclosure framework with approximately 216 questions. BRSR Core is a subset of key ESG indicators (around 9 KPIs) that must undergo independent assurance. BRSR Core was introduced in 2023 to make assurance practical and focused.
BRSR must be included in the company's Annual Report, which is typically filed within 6 months of the financial year end. For FY 2025-26, the Annual Report is usually filed by September 2026.
SEBI has not specified explicit monetary penalties for BRSR non-compliance. However, non-compliance is flagged by stock exchanges and can adversely affect ESG ratings, investor confidence, and eligibility for green finance and ESG indices.
BRSR Core assurance is being phased in: top 150 companies from FY 2023-24, top 250 from FY 2024-25, top 500 from FY 2025-26, and top 1,000 expected from FY 2026-27. Assurance must be conducted by an independent provider using recognised standards like ISAE 3000 or AA1000AS.
BRSR is India-specific and mandatory for listed companies, while GRI is a global voluntary framework. BRSR follows a fixed format with standardised questions, whereas GRI allows topic-based reporting. Many BRSR indicators are aligned with GRI Standards, making dual reporting feasible.
Yes. BSE requires BRSR data to be filed in XBRL (eXtensible Business Reporting Language) format. RSustain India's BRSR XBRL Filing tool can convert your BRSR data to BSE-compliant iXBRL format.
BRSR follows a three-section format: Section A (General Disclosures), Section B (Management and Process Disclosures), and Section C (Principle-Wise Performance covering all 9 NGRBC principles with Essential and Leadership indicators).
BRSR compliance costs vary based on company size, data readiness, and assurance requirements. Basic BRSR filing support typically ranges from INR 3-8 lakh. BRSR Core assurance can cost INR 8-25 lakh depending on scope. RSustain India offers structured programmes starting at INR 8 lakh for the complete 12-week Assurance Sprint.
