Department of Transportation
The Department of Transportation (DOT) conducts research to examine potential climate change impacts on transportation, methods for increasing transportation efficiency, and methods for reducing emissions that contribute to climate change. DOT’s Center for Climate Change and Environmental Forecasting coordinates transportation and climate change research, policies, and actions within DOT and promotes comprehensive approaches to reduce emissions, address climate change impacts, and develop adaptation strategies. DOT also contributes directly to USGCRP’s National Climate Assessment through focused research such as the Center’s Gulf Coast Studies.
The Federal Highway Administration (FHWA), the Federal Transit Administration (FTA) and other DOT agencies are also undertaking climate impact and adaptation studies (including vulnerability and risk assessments), working with science agencies to develop regional climate data and projections, methodological research, supporting pilot programs, and providing assistance to transportation stakeholders including state and local agencies. The Federal Aviation Administration (FAA), for example, conducts research to support USGCRP by working with NASA, NOAA, and EPA in the Aviation Climate Change Research Initiative (ACCRI) to identify and address key scientific gaps regarding aviation climate impacts and inform mitigation.
Other DOT initiatives address climate change and improve the sustainability of the U.S. transportation sector including: FAA and NASA manage the Continuous Lower Energy, Emissions, and Noise (CLEEN) program as a government industry consortium to develop technologies for energy efficiency, noise and emissions reduction, and alternative fuels; and FAA participates in the Commercial Aviation Alternative Fuels Initiative (CAAFI), a public-private coalition to encourage the development of alternative jet fuels.
