Mexico CNBV Sustainability Disclosure Rules: Sustainability disclosure rules require ISSB-aligned sustainability reporting by listed issuers and market participants

Summary

Mexico’s CNBV updated issuer rules (DOF 28 Jan 2025) require periodic sustainability information and an annual sustainability report aligned to ISSB standards (IFRS S1 and IFRS S2). Covered issuers must build governance, risk, metrics, and climate disclosure processes into annual reporting cycles and prepare for assurance expectations. Non-compliance risks CNBV enforcement and market consequences. Best practice is to implement financial-grade controls, align emissions data with RENE where relevant, and maintain audit-ready documentation.

What’s Required

Under the CNBV modification to the “Disposiciones de carácter general aplicables a las emisoras de valores y a otros participantes del mercado de valores,” covered entities must:

  • Prepare and publish a standalone annual sustainability report (or sustainability information within the required structure), aligned to ISSB standards referenced by CNBV (IFRS S1 and IFRS S2, and future ISSB standards as applicable).

  • Disclose governance, strategy, risk management, and metrics/targets consistent with ISSB architecture, including climate-related disclosures under IFRS S2.

  • Integrate reporting into annual filing workflows: establish internal controls, sign-offs, and documentation comparable to financial reporting processes.

  • Address assurance expectations: market guidance and professional commentary indicate staged assurance (limited then reasonable) as the regime matures, so issuers should design evidence-ready processes.

Important Deadlines

  • Publication date: 28 January 2025 (DOF publication via SIDOF).

  • Phasing: Implementation staging is referenced in market guidance and should be mapped to the issuer’s annual reporting calendar and CNBV filing requirements.

Current Status

  • In force / effective as updated CNBV reporting requirements, with the consolidated CNBV dispositions reflecting the DOF publication date.

Penalties for Non-Compliance

Potential consequences include:

  • CNBV administrative enforcement for incomplete, late, or misleading disclosures,

  • market consequences (investor actions, listing-related scrutiny),

  • potential liability exposure where disclosures are false or insufficiently supported.

Examples of Known Violations

Common disclosure-regime failure modes include:

  • reporting that is not aligned to the mandated standards (partial alignment, missing required pillars),

  • weak climate scenario analysis or lack of documented methodology,

  • unsupported metrics (emissions, financed emissions if applicable, targets),

  • greenwashing risk from inconsistent statements across investor materials vs CNBV filings.
