President Obama used his executive powers to take action against greenhouse gas pollution by directing the Environmental Protection Agency to develop new regulations for the reduction of carbon emissions from heavy-duty trucks.  

New York Times : “The president said the Transportation Department and the Environmental Protection Agency would draft new fuel economy standards for trucks by March 2015 so that they could be completed a year after that as he rushes to put in place a new regulatory structure before leaving office.”  

“Car and truck manufacturers in the United States have lobbied heavily against aggressive increases in federal fuel economy standards, saying that they could increase vehicle prices and diminish safety.”  

“Pollution from transportation is the nation’s second-largest source of greenhouse gas pollution.”
