AG Bonta today secured a preliminary injunction in the ongoing challenge against the U.S. Environmental Protection Agency’s (EPA) attack on California’s emission standards. Today, the district court rejected EPA’s reclassifications of the Clean Air Act waivers and is now requiring the EPA to withdraw or correct its unlawful reclassifications and refrain from giving them any effect.
"When it comes to environmental integrity, posterity demands that we act. […] For 50 years, both Democratic and Republican administrations have upheld California’s authority to enforce state emission standards, but this administration thinks it can roll back the clock and sow chaos even while our lawsuit plays out in court. […] Federal emission standards should be a baseline to protect our future, not a ceiling to limit it." – AG Bonta
