Brazil Reverses Course on ESG Disclosure, Moves to Voluntary Sustainability Reporting Framework

Brazil has unexpectedly revised its sustainability disclosure framework, shifting from mandatory to voluntary reporting for publicly listed companies just months before the rules were due to take effect.

The country's Securities and Exchange Commission, known as the Comissão de Valores Mobiliários (CVM), announced amendments to its sustainability reporting regulation that remove the obligation for listed companies to publish annual sustainability and climate-related disclosures aligned with International Sustainability Standards Board (ISSB) standards. The mandatory reporting requirement had been scheduled to apply to fiscal years beginning on or after January 1, 2026.

The change represents a major policy reversal for Brazil, which had been widely recognized as one of the first major economies to fully embrace ISSB-based sustainability reporting requirements. In 2023, Brazilian authorities announced plans to make sustainability and climate disclosures mandatory for public companies, positioning the country as an early adopter of the IFRS Foundation's global sustainability reporting framework.

A New "Comply or Explain" Model

Under the revised framework, sustainability reporting will remain available voluntarily. However, companies that choose not to publish sustainability reports will be required to publicly explain their decision.

According to the CVM's updated regulation, companies opting out of sustainability reporting must issue a formal market announcement explaining the reasons for their decision. The disclosure must be made when annual financial statements are filed in 2027, creating a transparency mechanism designed to maintain investor visibility into reporting practices.

The regulator has also retained the ISSB-based standards as the reporting framework for companies that decide to continue providing sustainability disclosures. This means organizations that voluntarily report will still use internationally recognized standards designed to improve consistency and comparability of climate and sustainability information.

The move effectively transforms Brazil's sustainability disclosure regime into a "comply or explain" model, similar to governance and reporting approaches used in several financial markets worldwide.

What Are ISSB Standards?

The ISSB was established by the IFRS Foundation to develop a globally consistent baseline for sustainability-related financial disclosures. Its two primary standards, IFRS S1 and IFRS S2, focus on sustainability-related financial information and climate-related risks and opportunities.

The standards are intended to provide investors with decision-useful information about how sustainability issues may affect a company's financial performance, strategy, governance, and risk management.

Global adoption of ISSB standards has accelerated in recent years. According to the IFRS Foundation, dozens of jurisdictions are incorporating ISSB standards into regulatory frameworks, representing a substantial share of global GDP, market capitalization, and greenhouse gas emissions.

Brazil's earlier decision to adopt ISSB standards was viewed as a significant milestone because it demonstrated how emerging markets could align sustainability reporting with international financial disclosure practices.

Why the Decision Matters

The shift comes at a time when sustainability reporting requirements are evolving rapidly around the world.

In Europe, policymakers have recently proposed adjustments to sustainability disclosure obligations under the Corporate Sustainability Reporting Directive (CSRD), while regulatory approaches in the United States continue to face legal and political challenges. These developments have contributed to a broader debate about the pace, scope, and complexity of ESG disclosure requirements.

Brazil's revised approach may reduce compliance costs and reporting burdens for some companies, particularly those that have been preparing for mandatory disclosure requirements. However, it could also create uncertainty for investors seeking standardized sustainability information across listed companies.

Investors increasingly rely on climate and sustainability data to assess risks related to climate change, supply chains, biodiversity impacts, workforce management, and corporate governance. Consistent reporting frameworks help improve comparability between companies and support capital allocation decisions.

Continued Expectations for Transparency

Despite the move away from mandatory reporting, sustainability disclosures are unlikely to disappear from Brazil's corporate landscape.

Many publicly listed companies already provide ESG information voluntarily to meet investor expectations, access sustainable finance markets, and support stakeholder engagement. Financial institutions, multinational corporations, and companies operating in global supply chains often face disclosure requests from investors, customers, and lenders regardless of domestic reporting mandates.

In addition, the CVM's decision to require explanations from companies that choose not to report may create reputational incentives for continued disclosure. Investors and analysts will be able to assess not only the sustainability information provided by reporting companies but also the rationale given by organizations that decline to participate.

The updated framework also preserves ISSB standards as the reference point for reporting, helping maintain alignment with international disclosure practices. This could allow companies to continue meeting the expectations of global investors while giving businesses greater flexibility regarding participation.

Implications Ahead of COP30

The policy change is particularly notable as Brazil prepares to host COP30, the United Nations climate conference scheduled to take place in Belém in 2025. Sustainability disclosure and climate transparency have become increasingly important topics within global climate policy discussions, especially regarding private-sector accountability and investment flows.

For companies operating in Brazil, the immediate impact will be a reassessment of sustainability reporting strategies. Organizations that had been preparing for mandatory compliance must now decide whether to continue with voluntary disclosures, weighing reporting costs against investor expectations and market credibility.

For investors, the new framework creates a more flexible but potentially less standardized reporting environment. The effectiveness of the revised approach will likely depend on how many companies choose to continue reporting and how stakeholders respond to firms that opt out.

As sustainability disclosure regulations continue to evolve globally, Brazil's decision highlights the ongoing tension between expanding transparency requirements and reducing regulatory burdens on companies. The coming years will reveal whether a voluntary, explain-based model can deliver the level of sustainability information investors increasingly demand.
