Transportation is vital to our economy and quality of life. But it is also the primary cause of U.S. oil dependency, and is responsible for more than a quarter of U.S. emissions of the greenhouse gases that are warming our planet. This report examines whether we can substantially reduce greenhouse gas (GHG) emissions from U.S. transportation. Report authors David Greene and Steve Plotkin provide three plausible scenarios of technology, policy, and public attitudes that result in cost-effective GHG reductions throughout the transportation sector. The High Mitigation Scenario shows we can reduce GHG emissions from transportation by as much as 65 percent below today’s levels by 2050. In order to do so, we need action on three fronts: targeted public policies, technological progress, and commitment from Americans as consumers and citizens.
