Fifteen US states seek to block Obama's clean power plan

Attorneys general for 15 other states issued a statement supporting the EPA rules to cut emissions and saying they would oppose legal efforts to block them

Fifteen state attorneys general petitioned a federal court in Washington on Thursday to block new US rules to curb carbon emissions from power plants, in the first of several expected legal challenges to the Obama administration measure.

States that oppose the Environmental Protection Agency's (EPA) clean power plan filed for the stay in the US court of appeals for the DC circuit. The states asked for a ruling by 8 September, one year before they need to submit compliance plans to the EPA.
