Sustainability reporting sprint — SEC climate rule FY2025 data controls
Large accelerated filers must have auditable greenhouse-gas, climate risk, and expenditure controls locked by August 2025 to support the U.S. SEC’s new climate disclosure requirements that begin with FY2025 Form 10-K filings.
Executive briefing: The U.S. Securities and Exchange Commission’s climate disclosure rule (Release Nos. 33-11275; 34-99678) requires large accelerated filers with calendar fiscal years to start reporting Scope 1 and Scope 2 emissions, climate-related financial impacts, and governance on their FY2025 Form 10-K filings in early 2026. That leaves only a few months after mid-year close to harden internal controls over greenhouse-gas inventories, scenario analysis, and spend tracking. Controllers, sustainability officers, and CIOs need to stabilise data pipelines by August 2025 so auditors can test design and operating effectiveness before year-end.
Control environment checkpoints
- Financial statement impact. Article 14 of the final rule compels disclosure of capitalised costs, expenses, charges, and losses tied to severe weather and climate targets when any threshold exceeds 1% of the relevant line item, necessitating chart-of-account updates and tagging.
- Governance evidence. Item 1501 of Regulation S-K requires boards to describe oversight of climate risks, while Item 1502 demands management process detail—documentation must be audit-ready.
- Attestation runway. The rule mandates limited assurance over Scope 1 and Scope 2 data starting with FY2029, but auditors will begin walkthroughs during FY2025 to establish baselines and independence.
Operational build
- Align enterprise emissions inventory tools with the Greenhouse Gas Protocol and SEC calculation constraints, producing monthly variance analysis and evidence logs.
- Automate severe weather impact capture by integrating facilities, insurance, and ERP data, mapping to Reg S-K Item 1502(c) risk management disclosures.
- Embed disclosure controls within SOX 404 scoping so CFO certifications cover sustainability metrics alongside financial statements.
Enablement moves
- Create joint sustainability-finance steering committees to prioritise system integrations and attestation readiness.
- Run mock disclosure committee sessions using draft climate narratives to stress-test governance and documentation.
- Coordinate with external auditors on evidence expectations to avoid year-end remediation work.
