Environmental, Social and Governance (ESG) reporting has rapidly evolved from a voluntary sustainability initiative into a strategic business requirement. In India, the Securities and Exchange Board of India (SEBI) has significantly strengthened ESG disclosure requirements through the introduction of BRSR Core, a focused and assured subset of the Business Responsibility and Sustainability Report (BRSR). The framework is being phased in and is expected to cover the top 1,000 listed entities by FY 2026-27. :contentReference[oaicite:0]{index=0}
As mandatory assurance requirements expand, leading Indian companies are investing heavily in ESG data management, sustainability governance, carbon accounting and supply chain transparency to stay ahead of compliance obligations and investor expectations. :contentReference[oaicite:1]{index=1}
What Is BRSR Core?
BRSR Core is a SEBI-prescribed subset of ESG disclosures within the broader BRSR framework. It focuses on key sustainability indicators that require greater transparency, consistency and third-party assurance. The framework was introduced to improve the reliability and comparability of ESG disclosures among listed companies. :contentReference[oaicite:2]{index=2}
While BRSR reporting is already mandatory for India's top 1,000 listed companies, BRSR Core introduces a more rigorous assurance mechanism covering critical ESG performance metrics. :contentReference[oaicite:3]{index=3}

How Leading Companies Are Preparing
1. Building ESG Data Management Systems
Companies are implementing centralized ESG data collection platforms to capture environmental and social performance metrics from multiple business units.
Reliable and auditable data is becoming essential as ESG disclosures move toward assurance-based reporting. :contentReference[oaicite:6]{index=6}
2. Strengthening Internal Governance
Boards and executive leadership teams are establishing ESG committees, assigning sustainability responsibilities and integrating ESG goals into overall corporate strategy.
Governance structures help ensure accountability and improve the quality of ESG reporting.
3. Conducting Carbon Footprint Assessments
Many organizations are measuring Scope 1, Scope 2 and in some cases Scope 3 greenhouse gas emissions to establish baseline sustainability performance and prepare for future climate-related disclosures.
4. Improving Supply Chain Transparency
BRSR Core extends beyond direct operations. Companies are increasingly engaging suppliers and value-chain partners to collect sustainability information and improve ESG performance across the supply chain. :contentReference[oaicite:7]{index=7}
