BRSR(Business Responsibility and Sustainability Reporting) is SEBI's mandated ESG disclosure framework for India's top 1,000 listed companies. Every company in India's top 1,000 must file a Business Responsibility and Sustainability Report with their annual report under SEBI's LODR regulations.
BRSR Core is the critical subset of BRSR that requires independent third-party assurance. It focuses on quantitative, GHG-linked KPIs — making accurate carbon accounting software essential for BRSR Core compliance.
