Public Transportation’s Role in Responding to Climate Change

The Federal Transit Administration (FTA) collects and analyzes data from across the country on public transportation fuel use, vehicles deployed, rides taken, and other key metrics. These data, taken from the National Transit Database and combined with information from the U.S. Department of Energy and the U.S. Environmental Protection Agency, provides valuable insight into the impacts of automobile, truck, SUV, and public transportation travel on the production of greenhouse gas emissions. National level data show significant greenhouse gas emission savings by use of public transportation, which offers a low emissions alternative to driving. This paper presents an analysis of the data and frames it in a broader context. It concludes with a description of FTA actions that address climate change.
