President Barack Obama will announce today a proposal that will require large trucks to increase fuel efficiency. According to TheHill.com:

Obama is slated to issue a directive that expands vehicle mileage rules to include big trucks for the first time beginning in model year 2014. The president is expected to offer comments on the announcement later this morning.

The directive will also require continued mileage improvements in cars and light-duty trucks after model year 2016, when the current efficiency and greenhouse gas rules end.

The effort also includes new support for the development of electric vehicles, an administration official said.

Earlier this year, the EPA and the National Highway Traffic Safety Administration finalized a joint rule creating new fuel efficiency and greenhouse gas emissions standards for cars and light-duty trucks. To read more about that program, click here.
