This Blueprint is a strategy to cut all greenhouse gas emissions from the transportation sector by 2050 and improve overall transport sector efficiency. The plan covers road, off-road, maritime, aviation, and rail transportation. The decarbonization approach focuses on three areas: 1) increasing convenience with walkability and cycling access, co-ordinated land use and transportation system development; 2) enhancing efficiency-public transportation, modal shift for passengers and freight, and improved efficiency of all vehicles; and 3) promoting clean vehicles-zero-emission vehicle fuels and the infrastructure to support them. Since 2025, however, the implementation of the plan has effectively ceased, with the Trump administration withdrawing support for key enabling policies and ceasing the funding and federal coordination needed for its delivery.
