On Tuesday, President Barack Obama will visit a Safeway (SWY) supermarket distribution center near Washington D.C. to promote a series of measures meant to enhance the nation’s environmental efforts.

In his remarks, Obama is anticipated to announce that he has ordered higher fuel-efficiency standards for medium- and heavy-duty trucks. The Environmental Protection Agency (EPA) will have until March 2016 to issue the new standards, the Associated Press notes.

Obama will highlight increased fuel-efficiency requirements as a way to reduce greenhouse gases, potentially blunting the impact of climate change. The move is also meant to show that the president can act on the environment without congressional action.

The Obama administration claims that previous tightening of fuel-efficiency standards for trucks will result in cost savings of $50 billion for trucking operators due to lower fuel purchases.

In addition to the higher fuel-efficiency standards, Obama will likely urge Congress to halt subsidies to fossil fuel producers. Previous calls to end the subsidies have not produced any congressional action, however.

The Obama administration boosted vehicle fuel efficiency standards in 2012 as part of its campaign against climate change.
