Legal Updates

New Deadline Set for California Climate Disclosure Rules

ESG Collaborative Update

On September 27, California Governor Gavin Newsom yielded to political pressure to provide workable frameworks for the Climate Corporate Data Accountability Act (SB 253) and the Climate-Related Financial Risk Act (SB 261) when he signed into law a bill amending both provisions, SB 219. We summarized the impact of the California climate disclosure legislation package in a previous issue of ESG Collaborative Update. SB 219 is a moderate version of the amendments Governor Newsom proposed in June 2024, which were rejected by the California legislature. Whether his efforts to keep the legislation package on track will be successful remains unclear, as litigation challenges against both SB 253 and SB 261 continue in the U.S. District Court for the Central District of California (U.S. Chamber, et al., C.D. Cal., Case 2:24-cv-00801 (Jan. 30, 2024). Later this month, the court will hear oral argument on dispositive motions in the case.

Despite the litigation uncertainty, the key takeaway is that the first reporting deadlines will still begin in 2026. Entities that do business and sell products in California would be wise to begin preparing now to comply with the nation’s most extensive mandatory disclosure reporting requirements on greenhouse gas emissions.

The following tables summarize the key changes implemented by SB 219.

RequirementSB 253As Amended by SB 219
Deadline for promulgation of CARB regulationsOriginal deadline was January 1, 2025CARB will now have until July 1, 2025

To comply with these requirements, covered entities will need to assess and develop internal controls around accounting, planning, operations, and governance practices to ensure successful and accurate disclosures. We previously provided some practical suggestions for ensuring ESG disclosures are specific and accurate. Careful planning and review of ESG disclosures will be central to minimizing compliance and litigation risks associated with ESG-related litigation.

Members of our ESG Collaborative will continue to follow developments in the California climate disclosure litigation and legislative developments related to pending climate accountability legislation in other states.
