SEC Climate Rescission Comment Period Closes — Federal Mandate Now on Hold

The SEC's proposed full rescission of its March 2024 climate-related disclosure rules closed its public comment period August 3, 2026, with more than 18,000 submissions from investor groups, environmental organizations, state regulators, and industry associations. The 2024 rules had never taken effect due to an April 2024 stay and subsequent abandonment by the Commission; rescission, if finalized, would eliminate any federal climate disclosure mandate for public companies. A final Commission vote is not expected before late 2026 or early 2027. The practical consequence is not relief from disclosure obligations: existing materiality-based duties under Regulation S-K and S-X continue to require disclosure of material climate risk, and anti-fraud provisions apply to any voluntary sustainability claim in filings, sustainability reports, or marketing materials. Multi-jurisdictional counsel needs to map clients against California SB 253, EU CSRD, and ISSB-aligned frameworks concurrently — federal inaction does not simplify the landscape, it fragments it.
