The transportation sector accounted for roughly 28 percent of the United States’ total greenhouse gas (GHG) emissions in 2016 and the majority of these emissions (60 percent) come from light-duty vehicles, like the car you likely drive to work every day. Given the significant share of national emissions that result from our daily driving habits and personal transportation activities, many cities and regional governments are exploring how to reduce transportation emissions through infrastructure planning and policy development. We are keeping an eye on several emerging trends that are likely to shape and define how communities work towards reducing their transportation-related emissions.
