The U.S. Transportation Department said on Thursday it would award $6.4 billion over five years to states to fund projects to reduce greenhouse gas emissions.

The funding, part of a $1 trillion infrastructure bill approved by Congress in November, will help states fund trail facilities for pedestrians and bicyclists and projects that support the deployment of alternative fuel vehicles…

Other projects that could be funded include those aimed at reducing traffic congestion and travel demand strategies; truck stop and port electrification systems; public transportation projects such as bus rapid transit corridors or dedicated bus lanes and infrastructure-based intelligent transportation systems and replacing street lighting and traffic control devices with energy-efficient alternatives…

Transportation accounts for the largest share of U.S. greenhouse gas emissions – around 27% in 2020. The administration says despite various roadblocks it can still achieve a goal of slashing greenhouse gas emissions by at least 50% below 2005 levels by 2030.
