Concentrations of Pollution in Oregon

Air Quality Impacts of the Proposed Expansion of Oregon's Clean Fuels Program

About the Project

As part of a state-wide effort to reduce carbon emissions, the Oregon Department of Environmental Quality is considering an expansion of the state's Clean Fuels Program (CFP). Adopted in 2015, the CFP sets a state-wide target for the average amount of carbon intensity (carbon emissions per unit) for transportation fuels. This target declines over time, and creates an incentive for fuel suppliers to bring cleaner, renewable fuels, like electricity, biodiesel, renewable natural gas, or ethanol, to the Oregon market. In addition to being lower-carbon emissions, these fuels also typically reduce emissions of other air pollutants, like particulate matter, and chemicals that contribute to the formation of Ozone or smog.

Researchers from the University of California, Davis, have modeled air quality effects of the vehicles and fuels that would be used to meet the expanded CFP.
