On October 14, 2025, the California Air Resources Board (CARB) quietly announced it was delaying its release of a proposed rulemaking on California’s climate laws.

While the rules were originally mandated by January 1, 2025, a statutory amendment in 2024 pushed that deadline to July 1, 2025. As that date came and went without any proposed rulemaking, CARB announced its intent in a public workshop on August 21, 2025, to publish proposed rules on October 14. On that date, CARB instead posted a sentence on the “resources” section of its website that read, “CARB is proposing an updated timeline for bringing the initial rulemaking (including the fee-related provisions) to the board in Q1 2026.”
