The California Air Resources Board (CARB) has proposed to repeal the High-Priority and Drayage components of the Advanced Clean Fleets (ACF) regulations. The proposal also includes changes to the Low Carbon Fuel Standard (LCFS) regulations and implements AB 1594 (flexibility for public utilities).

On July 28, 2025, the U.S. Environmental Protection Agency (EPA) eliminated the positions and unit responsible for maintaining the Extended Input-Output (EEIO) model, a key federal tool used to calculate Scope 3 greenhouse gas (GHG) emissions. The move signals a likely end to federal support for EEIO emissions factors, presenting challenges for companies preparing to comply with California’s landmark climate disclosure law, SB 253 (as amended by SB 219). As federal involvement recedes, the private sector and California regulators may fill the gap, introducing uncertainty about how Scope 3 emissions will be quantified going forward.

On July 28, 2025, the U.S. Environmental Protection Agency (EPA) announced a settlement with Pacific Gas & Electric (PG&E) for failing to promptly report an accidental release. This is the first-ever settlement for the failure to comply with the U.S. Chemical Safety and Hazard Investigation Board (CSB) Accidental Release Reporting Rule (Reporting Rule).

On July 23, 2025, the White House released “Winning the Race: America’s AI Action Plan” (“AI Action Plan”), outlining over 90 planned federal policy actions the Trump administration plans to implement to speed up artificial intelligence development across the United States. This rapid growth in domestic AI will result in an unprecedented U.S. demand for energy and require siting of significant electric generation assets to operate supporting infrastructure. Electricity demand from data centers represents a major new source of electricity demand and redundancy that will likely require a modernized approach to permitting and regulation to support sufficient growth on the Trump administration’s desired trajectory. For additional information on the impact of AI growth and the challenges of associated data center permitting, see Sidley’s blog posts here and here.

The California legislature recently passed SB 131 and AB 130, two bills designed to streamline environmental review under the California Environmental Quality Act (CEQA). While publicly touted as significant CEQA reform, the legal impact is more constrained, offering little relief for most industrial, commercial, or logistics-related development. SB 131 does, however, significantly expand the Governor’s discretionary power to designate certain large-scale private projects for streamlined CEQA treatment, offering potential opportunity for selected developers.

A new report by the U.S. Department of Energy provides a comprehensive assessment of the adequacy and reliability of the U.S. electric grid and warns that without urgent reforms and investment, the U.S. electric grid will be unable to support the nation’s economic ambitions, particularly in artificial intelligence (“AI”) and digital infrastructure. The report responds to recent executive orders emphasizing the need for a uniform, data-driven approach to evaluating grid reliability, particularly in the face of accelerating power plant retirements and surging electricity demand from data centers and AI applications.

On July 4, President Trump signed H.R.1—the “One Big Beautiful Bill,” referred to as the OBBB—into law. This sweeping tax and policy law, enacted through the process of budget reconciliation requiring a simple majority vote by Congress, carries significant implications for environmental funding, clean energy development, and climate-related programs administered by the U.S. Environmental Protection Agency (EPA), as well as the tax code. Much of the provisions affect programs and funding originally authorized under the 2022 Inflation Reduction Act (“IRA”), which was former President Biden’s signature budget reconciliation bill. Below, we outline some of the key features of the OBBB environmental and energy provisions.

In one of its many changes, the One Big Beautiful Bill Act, enacted on July 4, 2025, eliminated civil penalties for noncompliance with federal fuel economy standards. Specifically, Section 40006 of the Act amends the language of the Corporate Average Fuel Economy (CAFE) statute to reset the maximum civil penalty to $0.00. Although the statute and its implementing regulations otherwise remain in place, this amendment removes any civil penalties for producing passenger cars and light trucks that do not meet fuel economy requirements.
