On January 28, 2025 a resolution amending the General provisions applicable to issuers and other participants in the securities market (the "Resolution") was published in the Federal Official Gazette, to include obligations to issuers regarding sustainability information.

The Resolution became effective on January 29, 2025, which includes the obligation of securities issuers to disclose sustainability information which must be filed with the Mexican Banking and Securities Commission (the “CNBV”) and the corresponding stock exchange, beginning in 2026.

Resolution's objectives:

  • Promote the alignment of capital flows toward investments that enhance economic development by promoting environmental and social sustainability, transparency and long-term strategies in financial and economic activity;
  • Ensure that sustainability information is measurable, comparable and aligned with the IFRS Sustainability Disclosure Standards issued by the International Sustainability Standards Board; and
  • Provide investors with more elements for better investment decision-making, issuers with a more efficient risk management, and promote the growth of the Mexican securities market.

What is a sustainability report?

It refers to information on sustainability-related risks and opportunities of an issuer that could reasonably be expected to affect its cash flows, access to financing or capital costs in the short-, medium- or long-term, and that must include information on governance, strategy and management of such risks and opportunities, as well as metrics and targets.

Obligated entities? 

All issuers that maintain securities registered with the Mexican Securities Registry ("RNV").

Certain specific issuers are subject to the following particular requirements:

  • Financial entities acting as securities issuers: they must prepare sustainability information according with the legal framework applicable to each financial entity. This is also applicable to issuers that, through their subsidiaries, predominantly perform financial activities1 subject to the supervision of financial authorities.
  • SOFOMES E.N.R.: SOFOMES E.N.R. that issue securities other than debt instruments, and issuers whose predominant activity is the granting of credit, financial leasing or financial factoring, must comply with the sustainability reporting standards applicable to SOFOMES E.R.
  • Federal entities and municipalities: these are excluded from the obligation to prepare the sustainability report.
  • Foreign issuers: they must prepare sustainability information according with the IFRS Sustainability Disclosure Standards, or according with the sustainability reporting standards applicable in the issuer’s country of origin.

Disclosure requirements

The report must be prepared according to the IFRS Sustainability Disclosure Standards issued by the International Sustainability Standards Board, which comprise the IFRS-S described below, which set out the general disclosure requirements to be included in the sustainability information report:
