On Tuesday, a US appeals court upheld the Environmental Protection Agency‘s ruling, allowing California to establish its regulations for tailpipe emissions and electric vehicle standards.
The decision, made by a three-judge panel of the US Court of Appeals for the District of Columbia, dismissed a legal objection from 17 states led by Republicans and entities involved in producing or selling liquid fuels.
Under President Joe Biden in March 2022, the EPA restored California’s authority to implement its mandates regarding zero-emission vehicle sales and tailpipe emissions limits until 2025, overturning a previous decision made in 2019 by then-President Donald Trump.
California Governor Gavin Newsom said the “court sided with common sense and public health against the fossil fuel industry and Republican-led states. This ruling reaffirms California’s longstanding right to address pollution from cars and trucks.”

In May 2023, CARB requested EPA approval for a new waiver under the Clean Air Act to implement updated EV regulations starting in 2026.
The Alliance for Automotive Innovation, representing major automakers such as General Motors, Volkswagen, Toyota Motor, and others, raised concerns about California’s EV requirements in February.
Last month, the EPA finalized more stringent tailpipe emissions limits extending until 2032, which are less strict than initially proposed in early 2023.
To comply with regulatory goals, automakers must sell a minimum of 50% plug-in and electric vehicles by 2030. Initially, they were expected to sell 60% of EVs by 2030 and 68% by 2032 under the initial proposal.
