Brazil adopts ISSB standards, mandatory sustainability disclosure from January 2026

Brazil's Ministry of Finance and the CVM announced integration of ISSB's IFRS Sustainability Disclosure Standards, moving from voluntary adoption in 2024 to mandatory use on 1 January 2026. This phased approach offers a roadmap that India's own ISSB-alignment discussions may reference.

The Brazilian Ministry of Finance and the Comissão de Valores Mobiliários (CVM) announced their intention to integrate the IFRS Sustainability Disclosure Standards from the ISSB into Brazil's regulatory framework. The phased approach transitions from voluntary adoption starting in 2024 to mandatory use on 1 January 2026. Brazil has mandated IFRS Accounting Standards since 2010. The requirements form part of Brazil's Ecological Transformation Plan, which includes a $350 billion commitment in public and private infrastructure investment.

Brazilian listed companies and capital-market participants are directly affected, required to disclose sustainability-related risks and opportunities under the ISSB baseline. Officials stated the standards will strengthen Brazil's capital markets by amplifying transparency and helping companies attract capital and global investments. Finance Minister Fernando Haddad said the move would generate a virtuous cycle of greater transparency and commitment, enabling measurement against a global institutional metric so the market operates globally.

Indian companies and regulators tracking global ISSB adoption should monitor Brazil's phased timeline as a comparator for how emerging-market jurisdictions sequence voluntary then mandatory sustainability disclosure. Companies with Brazilian operations or investors should prepare for voluntary reporting from 2024 and mandatory compliance by 1 January 2026. The clear roadmap, commended by ISSB Chair Emmanuel Faber, illustrates the regulatory clarity that supports company and investor planning.
