The New York Times/ Greenwire – The United States can cut greenhouse gas emissions from transportation in half by 2050 with strategies ranging from cutting speed limits to imposing road pricing, according to a report released today by federal agencies and environmental and industry groups.

Examining about 50 transportation strategies, the report found transportation emissions could be reduced 24 percent by 2050 by acting to change travel behavior and land-use patterns. The emissions reduction hit 47 percent by adding road pricing techniques, ranging from pay-as-you-go insurance to charging Americans for every mile driven.

The report found environmental gains from advances in fuel efficiency would be mostly undermined by increased travel and population, making it important to address the efficiency of the transportation sector by investing in public transit, land-use planning and other low-carbon alternatives.
