America’s transportation system has emerged as Climate Enemy #1, with cars, trucks and other vehicles now representing the nation’s largest source of carbon pollution, and America producing more transportation carbon pollution per capita than any other major industrialized nation.
Increasingly, leaders in the United States and around the world are taking action to protect our climate from global warming. With 2016 likely to be the hottest year in human history, the need for further action is only growing more apparent, and more urgent. The success of the Regional Greenhouse Gas Initiative over the last decade shows that we can do more. To speed our progress toward a clean energy future, participating states should double its pollution reduction goal through 2030.
