Transportation Briefing Book
This briefing book breaks down several transportation policies being considered in states across the country. Each section includes a description of the policy, key facts and figures, and several examples of legislation passed or introduced on the state level. Sections include: active transportation, congestion pricing, electric vehicles, low carbon fuel standards, medium- and heavy-duty vehicle electrification, public transportation, transit-oriented development, the Transportation Climate Initiative, and vehicle miles traveled.
Transportation sector emissions are produced by light-, medium-, and heavy-duty vehicles, aircrafts, rail, and ships or boats. Tackling transportation emissions is critical to solving the climate crisis. In 2019, the transportation sector was the largest contributor to anthropogenic emissions in the United States, at 29% of the total. However, reducing emissions is not the only benefit from overhauling our current transportation system. Switching to cleaner and more varied forms of transportation increases quality of life in communities, decreases public health impacts from pollution, decreases motor vehicle injuries and fatalities, increases active lifestyles, increases mobility equity, and advances environmental justice. To achieve these benefits, it is critical that states employ transportation modes that center people in spaces, particularly people of color, rather than single-occupancy vehicles.
Transportation electrification is critical for decarbonization. States are working to make electric vehicles more affordable, charging stations more accessible, and public fleets less emissions-intensive. Moving away from internal combustion engines will improve air quality as well as reduce carbon emissions.
While electric vehicles are a key part of the solution to reducing transportation emissions, they are not the golden ticket to an improved transportation system. Single-occupant vehicles are not the most efficient form of transport, and reliance on cars requires significant infrastructure costs and resource extraction for car parts and batteries. Prioritizing active transportation and public transit are instrumental to creating thriving communities that work for everyone.
In order to reduce greenhouse gas emissions at the rate necessary to prevent the worst effects of the climate crisis, these policies need to work in tandem to transition our transportation system to a low-carbon one.
