Completing trail and active transportation networks connecting people to routine destinations by foot and bike are among the quickest and most affordable ways to increase emissions-free travel. Active transportation is an essential part of the solution to greenhouse gas emissions.

The transportation sector is the largest contributor to the greenhouse gas (GHG) emissions that drive climate change—contributing to over 29% of all GHG emissions in the United States. While most vehicle trips are within a 20-minute bike ride, it is not always safe or convenient to reach desired destinations by foot, bike or wheelchair. Safe, connected and convenient trail and active transportation networks can significantly reduce GHG emissions by reducing vehicle miles traveled and, in turn, cut air pollution and vehicle congestion. 

By including trail and active transportation networks as an eligibility in the following climate provisions of the BIL, federal funding opportunities are available to assist in achieving the mode shift necessary to address the climate impacts of the transportation sector.
