On behalf of 14 States, the State of Texas filed the opening brief in its challenge to the Environmental Protection Agency’s (EPA) Greenhouse Gas Endangerment Finding. The brief explains that the EPA failed to comply with the law when it issued its greenhouse-gas regulations and urges the court to strike down the Endangerment Finding.

In December 2009, the EPA finalized an Endangerment Finding that concluded that greenhouse gases (GHGs) pose a danger to human welfare.

The brief filed with the U.S. Court of Appeals for the D.C. Circuit asserts that the EPA’s Endangerment Finding is both arbitrary and capricious and failed to comply with the federal Clean Air Act.

In addition to the challenge to the Endangerment Finding, the States are also challenging five other regulations that are intended to further the EPA’s greenhouse-gas regulatory regime.
