In the case of Massachusetts v. Environmental Protection Agency, the Supreme Court ruled in favor of Massachusetts, which means that the EPA must reconsider its refusal to regulate greenhouse gas emissions and held that the EPA has a "statutory obligation" to regulate such admissions.
"In reaching its decision, the court's majority ruled that carbon dioxide and other emissions that trap heat in the earth's atmosphere fit the definition of "air pollutants" under the Clean Air Act and that the government thus has the authority to regulate them." (WP)
