The short answer

SEBI requires the top 1,000 listed companies by market capitalisation to publish a Business Responsibility and Sustainability Report (BRSR) covering environmental, social and governance disclosures, with key metrics under BRSR Core subject to assurance for the largest companies on a phased basis. Unlisted companies increasingly adopt ESG reporting to meet investor, lender and customer expectations.
