Mexico has introduced mandatory sustainability reporting for securities issuers and other securities market participants, including foreign issuers, as part of a regulatory reform aimed at enhancing transparency and risk management. The new requirements, published by the National Banking and Securities Commission (CNBV) on January 28, 2025, will require businesses to submit annual sustainability reports starting in 2026, aligning with international ESG standards and reinforcing Mexico’s commitment to a carbon neutral strategy. 

Under the reform, companies must adopt the International Sustainability Disclosure Standards (ISSB) and submit reports in accordance with IFRS S2 climate-related disclosures. These reports must cover governance, strategy, risk management, and sustainability-related targets and metrics. While foreign issuers can comply with their home country’s standards, they must demonstrate equivalence with IFRS requirements. 

A phased assurance process will be implemented, with no external assurance required for 2026 reports. By 2027, reports must include limited assurance, and by 2028, reasonable assurance by an external auditor will become mandatory. The reform also includes amendments to several articles that formalize sustainability reporting as a required component of securities registration, extend reporting deadlines for specific investment mechanisms, and clarify obligations for foreign issuers. 

Companies must now assess their ESG compliance scope, which extends beyond environmental concerns to include labor standards, data privacy, corporate governance, and workplace safety. Businesses are advised to proactively integrate sustainability into their strategies, revise internal policies to meet disclosure obligations, and work with legal counsel to ensure full compliance with the evolving regulatory landscape. 

By implementing these measures, Mexico is aligning its financial sector with global sustainability frameworks, reinforcing its role in ESG governance, and promoting long-term corporate accountability.
