President Obama highlighted heavy-duty American trucks as a source for pollution in America, highlighting his executive order to improve fuel efficiency for the vehicles.

Obama pointed out that heavy trucks accounted for 4 percent of vehicles on the highway, but were responsible for 20 percent of carbon pollution and fuel consumption in the transportation sector.

"I know when you're driving, sometimes it feels like it's more," he said.

Obama praised a truck at the scene for improving it's fuel efficiency by 75 percent.

"That's why I call this 'Super Truck,' " he said, pointing out that improvements in aerodynamics, tires and larger trailers made it more fuel-efficient.

"It's not just a win-win, its a win-win-win," Obama added. "You got three wins."
