Climate change impacts, such as more frequent and intense heat waves and flooding, threaten the considerable federal investment in transportation infrastructure. FHWA is partnering with state and local transportation agencies to increase the resilience of the transportation system to these impacts. FHWA has a number of tools and resources available under the adaptation tab at left.
In addition, with over a fourth of the climate change causing greenhouse gas (GHG) emissions in the U.S. coming from the transportation sector, FHWA is committed to reducing GHG pollution from vehicles traveling on our nation's highways. FHWA resources for developing effective GHG reduction strategies for transportation are available under the mitigation tab at left.
Adapting to climate changes already underway, while reducing GHG emissions to lessen future impacts, are both critical to FHWA's goal to improve highway system performance - particularly its safety, reliability, effectiveness, and sustainability.
