Brazil’s Securities Commission (CVM) issued Resolution CVM 227 amending Resolution CVM 193 to allow listed companies that intend to voluntarily publish a sustainability-related financial information report based on International Sustainability Standards Board (ISSB) standards IFRS S1 and IFRS S2 for financial years starting on or after 1 January 2025 to disclose their election to the market by 31 December 2025. Under the updated procedures, voluntary adoption for financial years starting on or after 1 January 2024 required a market notice by 31 December 2024, while voluntary adoption for financial years starting on or after 1 January 2025 can now be declared by 31 December 2025. CVM also reiterated that mandatory preparation and publication of the sustainability-related financial information report, based on standards issued by the CBPS, applies only to listed companies and does not apply to investment funds, securitisation companies, or other regulated entities; the change followed input received from the Brazilian Association of Listed Companies (Abrasca) on implementation of certain requirements. Resolution CVM 227 enters into force on 1 April 2025.
