Energy/Greenhouse Gas Emissions

Topic Home

The Energy and Greenhouse Gas (GHG) Emissions topic describes a range of programs, policies, case studies and other resources related to energy consumption and mitigation of greenhouse gas emissions from the transportation sector. For surface transportation, GHG mitigation strategies include efficient vehicles; low-carbon fuels; VMT reductions; operational efficiency of the system and vehicles; and construction, maintenance, and agency operations.
