Past federal transportation investments have made it easier and cheaper to travel by car, but at a high cost. Transportation is now America's #1 source of carbon pollution; air pollution from transportation cuts short thousands of lives each year, and thousands more die in car crashes. That's why Environment America and U.S. PIRG support the INVEST in America Act of 2021, which would help transform transportation by investing in roads, bridges, transit, and walking and biking infrastructure with an emphasis on fixing existing infrastructure and reducing pollution that harms our health and our climate.
