Transportation is now America’s number one source of global warming pollution, with greenhouse emissions from cars, trucks, buses and other vehicles surpassing every other source. We simply can’t solve global warming without changing how Americans get around.
The challenge is critical. Our transportation system is not only America’s biggest source of carbon pollution, but also one of the biggest sources in the world. Our country’s cars, trucks, trains and other vehicles emit more carbon dioxide than the entire economy of any single country other than China and India.
With renewable energy sources for generating electricity expanding rapidly, reducing pollution from our transportation system is the next major hurdle we must overcome in order to meet our commitment under the Paris Climate Agreement.
