Transportation is the second largest contributor to total U.S. greenhouse gas (GHG) emissions and responsible for about one-third of U.S. carbon-dioxide emissions from the combustion of fossil fuels. There are a variety of policy strategies that can be used to address GHG emissions from the transportation sector; this paper focuses on two such mechanisms. The […]
This brief discusses public policy tools available to reduce greenhouse gas (GHG) emissions from the transportation sector. Reducing GHG emissions from transportation, which comprise one third of total U.S. CO2 emissions, will need to be a key part of any strategy to limit economy-wide emissions. Transportation energy use and emissions are determined by three elements: […]
This report examines the prospects for substantially reducing the greenhouse gas (GHG) emissions from the U.S. transportation sector, which accounts for 27 percent of the GHG emissions of the entire U.S. economy and 30 percent of the world’s transportation GHG emissions. Without shifts in existing policies, the U.S. transportation sector’s GHG emissions are expected to […]
Transportation accounts for nearly a third of our nation’s greenhouse gas emissions, and its emissions are growing more rapidly than other sectors. In this report, authors David Greene and Andreas Schafer find that numerous opportunities are available now and in the future to reduce the transportation sector’s impact on climate. Many of these same actions […]
The United States consumes over 10 million barrels of oil per day moving people and goods on roads and rail throughout the country. Surface transportation generates over 23 percent of U.S. anthropogenic greenhouse gas (GHG) emissions. Transportation is the primary cause of U.S. oil dependence with its attendant risks to U.S. energy security. Contributions from […]
Recent technological advances have unleashed a boom in U.S. natural gas production, with expanded supplies and substantially lower prices projected well into the future. Because combusting natural gas yields fewer greenhouse gas emissions than coal or petroleum, the expanded use of natural gas offers significant opportunities to help address global climate change. The substitution of […]
