Brazil's CVM made ISSB reporting voluntary with conditions

Brazil's CVM regime no longer supports a simple instruction that every public company must start mandatory ISSB reporting in 2026. CVM announced the removal of that mandatory provision on 29 May 2026 through Resolution 244. The useful next step is a documented reporting choice, with the consequences of opting in kept visible. CVM announcement

This briefing addresses the CVM regime for Brazilian public-company reporting and English-reading teams coordinating it across borders. It does not decide obligations under other regulators, foreign listing rules, financing contracts or customer requirements. A change in this reporting regime is not a finding that the underlying climate risks have disappeared.

Resolution 244 revoked article 2 of Resolution 193. Published in the Diário Oficial da União on 1 June 2026, it applies to financial years beginning from 1 January 2026. A reporting plan that still cites the former mandatory provision needs review. Resolution 244 and CVM publication record

Treat this as a revision to a specific legal premise. Identify which board paper, reporting calendar and engagement scope depended on that premise. Keep unrelated reporting commitments in a separate register rather than cancelling an entire sustainability workstream because one requirement changed.

For entry under the new regime, the amended resolution requires at least three consecutive financial years of publication and an explicit, unreserved CBPS/ISSB conformity statement. Earlier adopters need a separate transition-relief assessment: the August circular describes circumstances in which extended relief can continue through the 2026 financial year, with the resulting nonconformity explained and reflected in the conformity statement. Leaving requires a market communication within the prescribed timetable. From 1 January 2027, a public company choosing not to file must explain management's reasons through a market communication. These are conditions of the published CVM regime, not optional editorial wording. Resolution 244, amended articles 1 and 3

That makes the reporting decision larger than choosing whether to issue a document this year. Management should understand the duration, basis and resourcing of an opt-in before communicating it. The original decision record below helps expose those commitments for qualified review.

CVM's technical areas issued Circular 2/2026 on 27 August. They explain that reports for 2024 or 2025 periods under the prior regime do not automatically acquire the new three-period commitment merely because they are published in 2026. Continuing with a financial year beginning from 1 January 2026 changes that analysis. Track the period covered separately from the publication date. Circular 2/2026, paragraphs 15–21

The circular also addresses statements that a report is aligned with, based on or inspired by CBPS or ISSB standards. Such language can suggest conformity; it is not a reliable shortcut around a complete basis-of-preparation assessment. Sharing a metric with those standards does not, by itself, determine the report's framework. Circular 2/2026, paragraphs 5–14

The distinction matters for an English annual-report introduction as much as for a Portuguese filing. Have the reporting owner review the exact statement, the report it describes and any translated version together. Avoid adding a broad conformity claim during copyediting after the technical basis has already been approved.

These fictional records show why the period covered matters more than a report's upload date. They do not determine an actual company's legal position.

For A, the fact that the file was uploaded in 2026 is insufficient to establish new-regime entry. For B, calling reporting voluntary does not eliminate the conditions attached to its election. Record the decision for the actual period rather than classifying both companies from a shared publication-year column.

Add a separate field for transition relief. Circular 2/2026, paragraphs 22–26, distinguishes the earlier regulatory extension from relief available within the standards themselves. Have the technical reviewer reconcile that choice with the precise conformity wording; do not leave an unreserved statement unchanged where the circular calls for a qualification.

The revised filing rule distinguishes a first reporting year, linked to the Formulário de Referência filing date, from subsequent years, due within three months of year-end or with the financial statements, whichever is earlier. The August guidance separately addresses prior-regime reports. Obtain a period-specific calendar rather than importing one generic 2026 deadline. Resolution 244, amended article 5 and CVM explanation of the circular

A useful management review asks three different questions: what must be communicated now, what must be maintained if the company opts in, and what remains necessary for other commitments. Assign each answer to an owner. If a deadline has already passed, escalate the actual position; do not reset the date in a planning sheet and call it a new obligation.

Preserve the source data, boundary decisions and methods already collected. A reporting choice can change the output without making those records worthless. Retention, access and any continuing use should still follow the company's reviewed controls. Before cancelling an evidence task, identify which decision or commitment it supports.

For a concrete record-design example, our emission-factor provenance register separates a factor's source, version and boundary. That article is a South Africa example; it supplies neither Brazilian factors nor CVM filing requirements. The transferable lesson is to keep the provenance behind a reported number visible.

Assess its exact reporting history, covered periods and communications against the current framework. A general statement that reporting is voluntary is insufficient to decide an individual company's continuation or exit position.

No label should substitute for a supported basis-of-preparation assessment. Review the report, its scope and the precise public wording together before approving a conformity statement.

Before changing an approved reporting plan, obtain genuine qualified technical review of the entity-specific decision and recheck the official CVM materials. The outcome should be a clear chosen route with supported communications, not a silent deletion of the old mandatory date.
