BRSR: Business Responsibility and Sustainability Report
Who must file BRSR?
Top 1000 listed companies by market cap (mandatory from FY 2022-23)
Deadline: Along with Annual Report (within 60 days of AGM)
Format: 9 sections covering 150+ data points
Assurance: Voluntary for FY 2023-24, mandatory from FY 2026-27
9 Sections of BRSR
Section A: General Disclosures (company profile, products, employees)
Section B: Management & Process Disclosures (ESG committee, policies)
Carbon Accounting: The New Skill for CAs
What is carbon accounting?
Measuring, reporting, and verifying greenhouse gas (GHG) emissions from business operations.
Scope 1: Direct emissions (company vehicles, factories)
Scope 2: Indirect emissions (purchased electricity)
Scope 3: Value chain emissions (suppliers, logistics, customers)
Standard: GHG Protocol (global standard), ISO 14064
ESG Assurance Services
Assurance means independent verification of ESG data accuracy (like financial audit, but for sustainability metrics).
Limited Assurance
Review-level engagement, less rigorous. "Nothing came to our attention" conclusion.
Reasonable Assurance
Audit-level engagement, highly rigorous. "In our opinion, data is fairly stated" conclusion.
SEBI Requirement: Top 150 companies must get reasonable assurance on BRSR core from FY 2026-27.

Challenges in ESG Reporting
Data Collection
ESG data scattered across departments (HR, operations, CSR). No centralized system.
Greenwashing Risk
Companies may exaggerate sustainability efforts. Assurance prevents this.
Lack of Standards
Multiple frameworks (GRI, SASB, TCFD, BRSR). Convergence needed.
Future Roadmap
FY 2025-26: BRSR core for top 250 companies
FY 2027-28: Extended to top 500 companies
