Transportation accounts for approximately one-third of greenhouse gas emissions in the United States. Reducing these emissions from this sector requires the involvement of each level of government—federal, state, and local, given their differing legal authorities and the breadth of actions needed. This chapter discusses strategies to reduce emissions from personal transportation, focusing on three components of transportation: vehicle technology, fuel content, and vehicle miles traveled. This chapter also briefly addresses strategies for reducing emissions from transport of goods by freight trucks, which carry more goods than planes, trains, and ships combined. National and international epidemiological studies of active transport (travel by bike or by foot) show reductions in mortality and morbidity from diabetes, heart disease, and other chronic diseases. This chapter also contains a textbox on how epidemiology has demonstrated the health co-benefits of active transport.
