Transportation is driving the world’s climate pollution

From land, air and sea, transportation is the fourth-largest source of global climate pollution.

Cleaning it up will take us far:

  • By 2040, electric cars will cut U.S. climate pollution by 600 million metric tons annually — that's close to what Canada emits in a year.
  • Sustainable fuels, along with tech innovation and other upgrades, can drop the carbon intensity of flying by more than 80%.
  • The same kinds of innovations could cut shipping’s impact on the climate by 95%.

This journey will lead to big results for stabilizing the climate and for cleaning the air. We're on the move.
