DOT Climate Change Center


The DOT Climate Change Center is the focal point for policy and action on climate change within the Department.  The Center is co-chaired by the policy and research units within the Office of the Secretary of Transportation (OST) and its membership is comprised of the DOT operating administrations and OST offices. An electric freight truck charging  A photograph of an electric freight truck plugged in and charging at an electric vehicle charging station.

Through strategic research, policy analysis, partnerships, coordination and outreach, the Center creates comprehensive and multi-modal approaches to reduce transportation-related greenhouse gases (GHG) and to improve the resilience of the transportation system to climate change impacts.  The DOT Climate Change Center plays a key role in implementing the climate and sustainability goal in the US DOT Strategic Plan

USDOT established the DOT Climate Change Center in 1999.  The Energy Independence and Security Act of 2007 (Public Law 110-140), Section 1101, formally established the Center as the Office of Climate Change and Environment.  It is codified in 49 USC Section 102(g).

National Performance Measure

To help address the climate crisis, FHWA proposes to amend its regulations governing national performance management measures to require State departments of transportation (State DOTs) and metropolitan planning organizations (MPOs) to establish  carbon dioxide (CO2) reduction targets and to establish a method for measurement and reporting.
