BRSR Primer: Understanding India’s Reporting Evolution

Business Responsibility and Sustainability Reporting (BRSR)

2/19/20263 min read

The landscape of corporate transparency in India has undergone a seismic shift. What once began as a voluntary ‘good-to-do’ exercise in CSR has matured into a rigorous, data-driven mandate known as BRSR (Business Responsibility and Sustainability Reporting).

For businesses today, BRSR isn’t just a regulatory hurdle—it’s a strategic opportunity to build trust, attract capital, and future-proof operations.

The Evolution: From Intent to Impact

To understand BRSR, we must look at its predecessor, the BRR (Business Responsibility Report) introduced in 2012. While BRR laid the groundwork, it was largely qualitative and focused heavily on charitable spending.

Recognizing the need for standardized, quantitative data that global investors could rely on, SEBI replaced BRR with BRSR in 2021. This new framework aligns India’s reporting with global standards like GRI, SASB, and TCFD, ensuring that Indian companies speak the international language of ESG.

Coverage: Who Must Report?

The mandate for BRSR is governed primarily by market capitalization, but its influence extends far beyond the top tier of the stock exchange.

  • The Top 1,000 Mandate: As of the current 2025-26 cycle, reporting is mandatory for the top 1,000 listed entities (by market capitalization) on the NSE and BSE. These companies must include the BRSR as part of their Annual Report.

  • The "Once In, Always In" Rule: Once a company crosses the market cap threshold and triggers the BRSR requirement, it must continue to report even if its market cap subsequently falls, ensuring longitudinal data consistency.

  • SMEs and Unlisted Entities: While not yet mandatory for smaller listed companies or unlisted entities, SEBI has introduced BRSR Lite. This is a voluntary, "pared-down" version designed to help smaller businesses build reporting capacity without the heavy compliance burden of the comprehensive format.

  • Foreign Subsidiaries: If an Indian subsidiary of a foreign multinational falls within the top 1,000, it must comply with BRSR, regardless of its parent company's global reporting standards.

The Three Pillars of BRSR

A BRSR report is structured into three distinct sections, moving from general identity to specific impact:

  • Section A: General Disclosures – The ‘Who’: Covers basic entity details, product portfolios, and operations.

  • Section B: Management and Process Disclosures – The ‘How’: Highlights the company's internal governance, policies, and leadership commitment to ESG.

  • Section C: Principle-wise Performance Disclosures – The ‘What’: The core of the report, mapped against the 9 Principles of National Guidelines on Responsible Business Conduct (NGRBC).

The Current Phase: BRSR Core and Value Chains (2025-26 Update)

As of February 2026, the framework has transitioned from a self-disclosure model to a high-fidelity verification system designed to ensure that sustainability claims are backed by audit-ready evidence.

  • BRSR Core: This is a subset of high-priority KPIs (like GHG emissions, water footprint, and gender diversity). Currently, the top 500 listed companies are required to obtain Reasonable Assurance (or Assessment) for these KPIs, a requirement that will expand to the full top 1,000 by next year.

  • The Value Chain Shift: Recognizing the complexity of supply chains, SEBI defines the "Value Chain" as partners cumulatively comprising 75% of purchases/sales (or those individual partners contributing 2% or more). For the top 250 entities, reporting on these partners is currently on a voluntary basis for FY 2025-26, helping companies build internal systems before mandatory reporting begins.

  • Green Credits: A new leadership indicator has been introduced, allowing companies to report on green credits generated or procured—incentivizing real-world environmental restoration.

Why It Matters Now?

The shift toward standardized, assured data signifies a move toward a more flexible and high-integrity landscape. For companies, this means:

  • Investor Readiness: Institutional investors now use BRSR Core data to assess risk. A robust report can directly lower the cost of capital.

  • Global Comparability: With the introduction of PPP-adjusted intensity ratios, Indian companies can now be fairly compared with global peers, highlighting our efficiency in a local context.

  • Operational Resilience: Mapping water intensity, energy usage, and workforce diversity often reveals hidden inefficiencies and risks within the business model.

Navigating the Path Ahead

The transition from BRR to BRSR Core marks India's entry into the premier league of global sustainability. However, the complexity of data collection—especially across fragmented value chains—remains a challenge.
