Cars, trucks, planes, trains, and ships make up the U.S.'s biggest source of greenhouse gas emissions — about one-third of the nation's total. Now, the Biden administration is laying out a strategy to clean up the transportation sector while also making it more convenient and just.
Four federal agencies unveiled a "national blueprint for transportation decarbonization" earlier this month, a collaboration they described as the first of its kind for the federal government. Co-published by the Departments of Energy, Transportation, and Housing and Urban Development, as well as the Environmental Protection Agency, the 88-page roadmap envisions a low-emissions mobility system that is "clean, safe, secure, accessible, affordable, and equitable, and provides sustainable transportation options for people and goods."
