The U.S. Supreme Court has agreed to hear a challenge to a key part of President Barack Obama's plan to mitigate the effects of climate change. The court agreed today to hear one of the questions presented by nine different petitioners about greenhouse gas regulations outlined in Obama's strategy, according to Reuters.

The issue examines whether the Environmental Protection Agency's decision to limit emissions from cars and trucks requires it to also establish emissions requirements for stationary facilities, such as factories or power plants.

The Supreme Court will decide whether the EPA should treat automobiles and so-called stationary sources differently, and if the agency overstepped its authority in regulating emissions for stationary facilities as part of its rules for cars and trucks. Oral arguments will likely begin early next year, and a ruling is not expected until mid-2014, reported Reuters.
