Brazil and ISSB reporting

On 24 April 2024 the Comissão de Valores Mobiliários (CVM) adopted Resolution 200, requiring Brazilian issuers to report using IFRS S1 and S2 from fiscal years beginning in 2026. Boards must integrate sustainability governance into Formulário de Referência filings, approve transition plans, and prepare for assurance on climate metrics. This landmark regulation positions Brazil among the earliest major economies to mandate ISSB-aligned sustainability reporting, reflecting the country's commitment to sustainable development and international capital market integration.

Brazilian Capital Markets Context

Brazil hosts Latin America's largest capital market through the B3 exchange, with listed companies spanning mining, agriculture, energy, financial services, and manufacturing sectors. Many Brazilian issuers face material climate-related risks and opportunities given the country's Amazon stewardship responsibilities, agricultural export economy, and renewable energy resources.

CVM's adoption of ISSB standards responds to investor demands for comparable, decision-useful sustainability information while positioning Brazilian companies for global capital access. The regulation builds upon voluntary sustainability reporting frameworks that many leading Brazilian companies already follow, establishing mandatory baseline requirements that raise market-wide disclosure standards.

Board Governance Disclosures

Companies must describe governance structures overseeing sustainability disclosures, including director skills and committee mandates. Resolution 200 requires issuers to explain how boards provide oversight of sustainability-related risks and opportunities, including committee structures, delegation arrangements, and escalation procedures.

Director competency disclosures should address sustainability expertise at board and committee levels. Companies should describe how sustainability considerations integrate with strategic planning, risk management, and performance evaluation processes. Stakeholder engagement mechanisms and board responsiveness to sustainability-related concerns require disclosure where material to understanding governance effectiveness.

Assurance and Audit Committee Responsibilities

CVM set a phased roadmap for limited assurance by independent auditors, increasing audit committee workload and oversight responsibilities. Initial phases require companies to prepare for assurance readiness, implementing internal controls over sustainability information comparable to financial reporting controls.

Audit committees must oversee assurance provider selection, scope definition, and findings resolution. The phased approach allows time for assurance provider capacity building and methodology development while moving toward strong verification of climate metrics. Audit committees should evaluate management's sustainability reporting processes, data quality, and control environment alongside traditional financial reporting oversight.

Value Chain and Scope 3 Considerations

Issuers must map supply-chain emissions and climate risks when material, demanding cross-functional governance and data collection capabilities. IFRS S2 requires disclosure of Scope 3 greenhouse gas emissions when material, presenting significant data collection challenges for companies with complex value chains.

Brazilian agricultural and commodity companies face particular challenges given dispersed supplier bases and limited upstream reporting infrastructure. Cross-functional coordination between sustainability teams, procurement, operations, and finance enables full value chain mapping. Materiality assessments should consider both upstream supplier impacts and downstream customer use and end-of-life emissions where significant.

Transition Planning Requirements

Resolution 200 requires disclosure of climate transition plans where companies have adopted net-zero or other climate commitments. Transition plan disclosures should address interim targets, capital expenditure requirements, technology assumptions, and governance mechanisms for plan execution and monitoring. Boards must approve transition plans and oversee progress against milestones. Investor communications should explain how transition strategies align with Paris Agreement temperature goals and Brazilian national climate commitments. Scenario analysis supporting transition planning should address multiple temperature pathways and policy scenarios relevant to company operations and markets.

Investor Communication Strategies

Refresh investor communications to explain board oversight of transition finance, risk appetite, and stakeholder engagement around ISSB adoption. Investor relations teams should prepare for improved sustainability-related inquiries following Resolution 200 setup.

Earnings communications and investor presentations should integrate sustainability performance alongside financial results. Board chairs and lead directors may participate in sustainability-focused investor engagement addressing governance arrangements and strategic oversight. Proxy statement and annual report disclosures require coordination to present consistent sustainability narratives across regulatory filings and voluntary communications.

Implementation Timeline and Preparation

Benchmark existing sustainability committees against CVM governance disclosure requirements and document board competency gaps. Companies should assess current reporting capabilities against IFRS S1 and S2 requirements, identifying data gaps and system improvements needed. Integrate greenhouse-gas accounting and scenario analysis workflows with financial statement controls ahead of assurance mandates. Training programs should educate board directors, management, and reporting teams on ISSB requirements and setup good practices. Early engagement with assurance providers supports readiness assessment and control improvement recommendations before mandatory assurance periods begin.
