What is BRSR? The Complete Guide to Business Responsibility and Sustainability Reporting in India
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.

1. What is BRSR?
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:
- Mandatory for top 1,000 listed companies by market capitalisation
- Standardised format with 216 questions across three sections
- Quantitative focus — measurable metrics, not narrative descriptions
- Annual filing as part of the company's annual report
- Aligned with global frameworks including GRI, UNGC, SDGs, and TCFD
2. History: From BRR to BRSR
India's ESG disclosure journey spans over a decade:
- 2012 — SEBI mandates Business Responsibility Report (BRR) for top 100 listed companies
- 2015 — BRR extended to top 500 listed companies
- 2019 — Committee on Business Responsibility Reporting recommends BRSR framework
- 2021 — SEBI notifies BRSR format (May 2021), voluntary for FY 2021-22
- 2022 — BRSR becomes mandatory for top 1,000 listed companies from FY 2022-23
- 2023 — SEBI introduces BRSR Core for assurance (July 2023)
- 2024 — Assessment or assurance of BRSR Core begins for top 150 companies
- 2026 — BRSR Core assurance extends to top 500 companies
3. Who Must File BRSR?
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:
- Top 150 companies — mandatory assessment or assurance from FY 2023-24
- Top 250 companies — mandatory from FY 2024-25
- Top 500 companies — mandatory from FY 2025-26
- Top 1,000 companies — expected from FY 2026-27
4. BRSR Format and Structure
The BRSR report is structured in three sections with a total of approximately 216 disclosure questions:
Section A: General Disclosures
Company details, products/services, operations, employees, CSR details, and transparency/compliance information. This section establishes the reporting boundary and entity profile.
Section B: Management and Process Disclosures
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.
Section C: Principle-Wise Performance
Detailed performance indicators for each of the 9 principles, split into Essential Indicators (mandatory) and Leadership Indicators (voluntary but increasingly expected).
5. The 9 BRSR Principles
BRSR is built on the National Guidelines on Responsible Business Conduct (NGRBC), which define 9 principles:
- P1 — Ethics, Transparency, and Accountability: Business integrity, anti-corruption, whistleblower mechanisms
- P2 — Products and Services: Sustainable sourcing, lifecycle impact, recycling, EPR compliance
- P3 — Employee Wellbeing: Workforce data, diversity, safety, benefits, training, equal opportunity
- P4 — Stakeholder Engagement: Identifying and engaging with affected communities and stakeholders
- P5 — Human Rights: Human rights due diligence, child labour, forced labour, remediation
- P6 — Environment: Energy, emissions, water, waste, biodiversity, EIA, pollution prevention
- P7 — Policy Advocacy: Responsible public policy engagement and trade association memberships
- P8 — Inclusive Growth: CSR, community development, procurement from MSMEs and marginalised groups
- P9 — Consumer Responsibility: Product safety, data privacy, customer complaints, responsible marketing
6. What is BRSR Core?
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.
7. BRSR Core Indicators
The BRSR Core KPIs that require assurance include:
- GHG Emissions — Scope 1 and Scope 2 emissions intensity (per revenue and per output)
- Water — Water consumption intensity and water discharge quality
- Waste — Waste generated, recycled, and safely disposed
- Energy — Energy consumption intensity and renewable energy share
- Workforce Diversity — Gender and differently-abled representation
- Safety — LTIFR (Lost Time Injury Frequency Rate) for employees and workers
- Human Rights — Complaints on child labour, forced labour, and wage theft
- Pay Equity — Median remuneration ratio (male vs female)
- Governance — Board diversity and training on ESG
8. BRSR Assurance Requirements
BRSR Core assurance must be conducted by an independent assurance provider. Key requirements:
- Assurance must follow recognised standards: ISAE 3000, ISAE 3410, AA1000AS, or equivalent
- Assurance providers must be independent of the reporting entity
- SEBI does not prescribe the assurance level; entities choosing assurance may opt for limited or reasonable assurance
- The assurance report must be included in the company's Annual Report
