Clean Vehicles

Clean Vehicles

In Oregon, the transportation sector is one of the largest contributors of greenhouse gas emissions, accounting for 35% of all emissions in 2019.  The combustion of fossil fuels in cars and trucks contribute the most GHG emissions.  Reducing the use of fossil fuels from cars and trucks will decrease GHG emissions, most significantly carbon dioxide (CO2), methane (CH4), and nitrous oxides (NOx). It will also reduce criteria pollutants and other toxic air pollutants (most significantly diesel particulate matter).

DEQ is reducing vehicle transportation-related emissions through a variety of efforts to address clean vehicles, clean fuels, and fewer miles traveled. These actions including both regulatory and voluntary efforts. In addition, DEQ collaborates with partner agencies (the Oregon Department of Transportation, the Oregon Department of Energy, and the Department of Land Conservation and Development) on the Every Mile Counts, effort to find ways to reduce transportation emissions by adopting cleaner fuels, using better vehicle technology, and ensuring there is adequate infrastructure to support the transition.
