Taking on the Transportation Sector

Nearing the first anniversary of the United States’ first greenhouse gas (GHG)  cap-and-trade program, members of the northeast Regional Greenhouse Gas Initiative (RGGI) joined with Pennsylvania to build on their effort to reduce GHG emissions. Governors from these eleven Northeast and Mid-Atlantic states signed a Memorandum of Understanding to establish the framework for a Low Carbon Fuel Standard (LCFS) by 2011.

The RGGI LCFS will operate in conjunction with national fuel economy standards that will increase the efficiency of passenger vehicles. A our new resource updates our comparison of fuel economy standards around the world and shows the fuel economy gains that will be made from these new standards.

In other climate and transportation news, we recently released a report on two modes of transportation that haven’t received a lot of attention from U.S. climate policymakers: the aviation and marine sectors. The report, Aviation and Marine Transportation: GHG Mitigation Potential and Challenges, finds that reductions in GHG emissions of more than 50 percent below business-as-usual (BAU) levels are possible by 2050. Though aviation and marine transportation currently represent only 3 percent of emissions, BAU CO2 emissions from the global aviation and marine transport sectors are projected to quadruple and nearly triple, respectively, by mid-century; controlling growth in these emissions will be an important part of reducing overall emissions from transportation.

Our President Eileen Claussen says, “Aviation and marine shipping are two of the fastest growing modes of transportation. Their greenhouse gas emissions are growing rapidly as well. To protect the climate, we need to reduce emissions across the entire economy. Aviation and marine shipping are part of the climate problem, and this report shows that they can be part of the solution.”
