Brazil Reconsiders Mandatory Sustainability Reporting Framework

Brazil is reevaluating its regulatory approach to corporate sustainability disclosures, initiating a fresh public consultation just months after shifting from mandatory requirements to a voluntary framework. The Securities and Exchange Commission, known locally as the CVM, has opened a dialogue to examine the advantages and disadvantages of different regulatory models for climate and general environmental disclosures.

Background of Regulatory Shifts

The regulatory trajectory in Brazil has seen multiple adjustments over recent years. Initially, the CVM established rules requiring public corporations to issue annual sustainability and climate-related reports aligned with international frameworks. These standards were drawn from the Brazilian Sustainability Pronouncements Committee, which based its guidelines on the general sustainability and climate reporting standards issued by the International Sustainability Standards Board.

However, the regulator altered course by amending the regulation to establish a comply-or-explain structure. Under this interim model, enterprises choosing not to file a sustainability report were permitted to do so provided they published a formal market justification. This policy change drew immediate resistance from various institutional investing entities, accounting bodies, and governance organizations. Critics contended that making disclosures optional would compromise data comparability, diminish alignment with global benchmarks, and obscure transparency for market participants.

Current Consultation and Hypotheses

The newly launched consultation aims to capture empirical evidence regarding multiple operational hypotheses. The CVM intends to evaluate whether voluntary frameworks fail to deliver sufficient data credibility and whether the reduction in capital costs driven by mandatory transparency outweighs incremental compliance burdens. Furthermore, regulators are assessing the disproportionate impact of compliance expenses on smaller companies versus larger corporations, and whether frequent regulatory adjustments inadvertently damage the predictability of the national regulatory environment.

Potential Regulatory Alternatives

Market participants and stakeholders have until late February 2027 to submit feedback on several proposed regulatory paths. The alternatives under review include:

• Maintaining the existing voluntary comply-or-explain regime while adjusting participation conditions.
• Phasing in mandatory obligations gradually based on company size or specific timelines.
• Mandating climate-related reporting exclusively while keeping broader metrics optional.
• Expanding mandatory disclosure mandates to encompass entities beyond publicly traded corporations.

The outcomes of this consultation will guide the CVM as it determines the final architecture for corporate reporting standards in the Brazilian market.
