California Expands Climate Regulation

The main change is a clearer, more concrete implementation picture: CARB has now approved initial SB 253 rules and the narrative adds specific enforcement and project-safety concerns around carbon capture. The story also reframes federal action as a sharper policy contrast, with California pressing ahead while Washington moves the other way.

California’s climate push has become more concretely operational: specific reporting deadlines, an injunction affecting part of the disclosure regime, and active carbon capture deployment now define the story. The addition of an operating storage project and the 2045 cap-and-invest extension make the state framework look more advanced and durable than before.

• CARB set August 10, 2026 as the first Scope 1 and Scope 2 reporting deadline.
• Scope 3 reporting is scheduled to begin in 2027.
• SB 261 financial-risk disclosure remains under injunction.
• California extended cap-and-invest through 2045.
• Carbon TerraVault I began injecting captured CO2 in Kern County.

The story now extends beyond California disclosure implementation to include a direct federal reversal: the SEC is moving to withdraw its climate disclosure rules, sharpening the state-federal divergence. California’s agenda also broadens to cap-and-invest through 2045 and carbon capture rulemaking, making the policy shift look more durable and wider in scope.

• SEC proposes to withdraw federal climate disclosure requirements.
• California cap-and-invest rules are being extended through 2045.
• California carbon capture and removal rules are still being drafted.
• Thresholds, fee structures, and enforcement discretion are still being set.
• Scope 3 and other challenged provisions remain legally unsettled.

The biggest change is a shift from simply noting California’s climate-disclosure rollout to emphasizing that implementation is now actively underway, with concrete compliance deadlines and clearer operational pressure on covered firms. The current version also adds that the framework may be influencing policy diffusion beyond California, especially in New York.

California is moving climate disclosure rules from adoption into implementation, with CARB approving initial regulations for emissions and financial risk reporting while legal challenges continue to slow parts of the framework.
