• U.S. Court of Appeals says the Environmental Protection Agency has ample scientific evidence to back up its decision to regulate greenhouse gases.
• The judges agreed that EPA made its case that greenhouse gases pose a threat to people and that human activities are involved in generating them.
• The court also told the private sector's Coalition for Responsible Regulation, Inc., which filed the case, that the EPA is required to consider costs only for the automobile industry.

From the article: 

Utilities and business cannot challenge U.S. Environmental Protection Agency (EPA) regulations on greenhouse gas (GHG) emissions, according to a decision by the U.S Court of Appeals released earlier this week. Petitioners in the case included states, the U.S. Chamber of Commerce and various players in the energy industry.
