In a landmark ruling that’s bound to eventually affect the operation of heavy trucks, the U.S. Supreme Court on Monday, April 2, ruled that the U.S. Environmental Protection Agency has the authority to regulate heat-trapping greenhouse gases emitted by vehicles.
The court also ruled that – unless the EPA can provide a scientific basis for not regulating the emissions – the EPA must take action.
The Bush administration has steadfastly refused to recognize greenhouse gases as a factor in global warming, and has refused to sign the Kyoto Protocol that puts a cap on the gases.
A dozen states, several cities and a collection of environmental groups filed lawsuits aimed at forcing the EPA to regulate greenhouse gases such as carbon dioxide.
California is one of 11 states that sued the federal EPA for not regulating greenhouse gas emissions as a pollutant. The San Francisco Chronicle reported Monday that California Attorney General Jerry Brown said the Supreme Court’s ruling “makes it very clear that California has a right to regulate greenhouse gases.”
