ESG reporting obligations updated with BRSR Core assessment or assurance option and mandatory green credits disclosure framework. Revisions require listed entities to adopt a BRSR Core subset for ESG reporting and permit third party assessment or assurance of core KPIs per Industry Standards Forum standards; boards must ensure provider expertise and absence of conflicts, reporting formats are updated to combine data and assessment approach and to capture assessor identity and type, and a new leadership indicator mandates disclosure of green credits by the entity and top value chain partners, while value chain ESG disclosures are deferred and made voluntary initially with optional retrospective reporting.
