Greening transportation

Cars, trucks, buses, trains, planes, ships — together they're the second largest source of global warming pollution in the U.S., and a major source of health-threatening air pollution.

We work with policymakers, businesses, and consumers to cut this pollution. This can break our dependence on oil, save money and create jobs.

Our solutions and successes

• 

  54.5 mpg for new cars

  Finalized standards mean major savings for consumers and a big drop in carbon pollution.

• 

  Cars and the environment

  A look at how cars have gotten cleaner slowly but surely over the decades, and why it matters.

• 

  Holding airlines accountable

  We're supporting EU efforts to reduce emissions in the courts and on the ad pages.

• 

  Cleaner diesel

  We helped win cuts of the thick, black puffs of smoke from trucks, trains and ships, so we can all breathe easier.
