Three judges serving on the U.S. Court of Appeals for the District of Columbia Circuit on Tuesday affirmed the Biden administration's 2022 decision to preserve California's strict emissions standards—dealing a blow to a coalition of right-wing state attorneys general and fossil fuel industry groups that had challenged the rules.The panel—made up of judges who were appointed by Democratic Presidents Joe Biden and Barack Obama—ruled that the U.S.
Circuit has reaffirmed California;s critical role in protecting its residents from harmful vehicle emissions, thereby benefiting the many states that rely on adoption of California's standards to achieve and maintain the Clean Air Act's air quality mandate,' said Berman. California's strict emissions standards have been adopted by 17 states and Washington, D.C. since they were first introduced.
