Seventeen states and the District of Columbia filed suit Tuesday to sue the Trump administration over the decision to abandon Obama-era vehicle emissions standards. The lawsuit targets the Environmental Protection Agency and its administrator, Scott Pruitt, stating that Pruitt acted "arbitrarily and capriciously" and without sufficient evidence when he moved to dismantle the 2011 policies. Pruitt has criticized and rolled back policies that planned to require vehicles manufactured in coming years to get at least 36 miles per gallon. California, a state included in the lawsuit, has specifically been operating under a waiver that allows it to hold separate stricter greenhouse gas emissions standards, but the Trump administration has proposed to dismantle those standards as well.
