Supreme Court Orders EPA to Reconsider GHG Regulation

Bloomberg. The US Supreme Court has ordered the US Environmental Protection Agency (EPA) to reconsider its refusal to regulate greenhouse gas (GHG) emissions.

In a 5-4 decision, the court said that the agency considered improper factors in 2003 when it decided not to order cuts in carbon emissions from new cars and trucks, and that the agency has the authority to regulate greenhouse gases.

The ruling doesn’t require the agency to impose new regulations, but it is a setback to automakers challenging the regulations mandating reductions in tailpipe CO2 implemented by California and adopted by other states.

Part of the argument made against the tailpipe regulations  was the contention that carbon dioxide is not an air pollutant subject to regulation under the Clean Air Act. The Supreme Court decision rejected that interpretation.

“EPA has offered no reasoned explanation for its refusal to decide whether greenhouse gases cause or contribute to climate change,” Justice John Paul Stevens wrote for the majority.

“Greenhouse gases fit well within the Clean Air Act’s capacious definition of ‘air pollutant,’” Stevens wrote.

Some analysis of this decision over on The Volokh Conspiracy. Among the questions is whether the EPA flubbed its own case.
