JACKSON, Miss. (AP) -- Mississippi has joined several other states in filing a challenge to the Environmental Protection Agency's finding that greenhouse gases are great enough to threaten public health and should face restrictions.
The EPA in December issued an "endangerment" finding about carbon dioxide and other greenhouse gases that allowed it for the first time to make rules restricting emissions under the Clean Air Act.
Mississippi Gov. Haley Barbour says Mississippi was among 11 states on Thursday to join in the lawsuit.
Barbour says the regulations would unnecessarily harm the economy of Mississippi and the United States by causing energy costs to increase and placing U.S. employers at a disadvantage to their foreign competitors. He says more regulation will drive up energy and consumer product prices.
