If you read that "from 2026 listed companies must publish a sustainability report", that information is OUT OF DATE. It was true until 29 May 2026.
| when | what changed |
|---|---|
| 2023 | Resolução CVM 193 Brazil becomes the first country in the world to adopt the ISSB standards (IFRS S1 and S2) for sustainability-related financial reporting. Designed as a phased regime: voluntary first, mandatory later. |
| 2024–2025 | Fase voluntária Public companies, funds and securitization firms may report voluntarily under IFRS S1 and S2. |
| 01/01/2026 | Seria o início da obrigatoriedade The original rule made reporting mandatory for fiscal years starting on or after 1 January 2026, WITH independent auditor assurance. The first mandatory reports would have come out in 2027. |
| 29/05/2026 | Resolução CVM 244 — REVOGA a obrigatoriedade Not a postponement: a repeal. Reporting reverts to entirely voluntary, effective for fiscal years starting 1 January 2026 — that is, it reaches the year already under way. |
| 01/01/2027 | Começa o "pratique ou explique" Companies that do NOT report must communicate their reasons to the market. The obligation to report is gone; the obligation to explain is not. |
Voluntary is not informal. Adopting binds the company for three fiscal years and exiting requires advance notice — the design prevents publishing in a good year and vanishing in a bad one.
| Mínimo de três exercícios consecutivos A company that adopts voluntarily must keep publishing for at least three consecutive fiscal years. Adopting is not reversible the following year. |
| Aviso prévio para descontinuar Discontinuing requires a market announcement by the filing date of the statements for the year immediately before the year of discontinuation. |
| Norma a seguir continua sendo a do ISSB Whoever reports must follow the Brazilian standards that correspond to IFRS S1 and S2. Voluntary does not mean free-form. |
We have no sustainability data at all. Our base comes from the annual and quarterly financial filings. ISSB reports do not pass through here, and this page is regulation, not our measurement. We say so because a page implying we measure ESG would be more useful to us and less true.

Checked on 1 September 2026 against the regulator's own announcement and an independent legal analysis. If the rule changes again this page goes stale — and the date above is what lets you distrust it.
