Oregon and Washington run their own declining carbon-intensity standards. They are separate from California’s Low Carbon Fuel Standard and from the federal Renewable Fuel Standard. The figures below are only what each state agency prints on the page linked in that section.
Oregon Clean Fuels Program
The Oregon Department of Environmental Quality describes the Clean Fuels Program on its overview. The baseline year is 2015. DEQ says that baseline represents gasoline containing 10 percent ethanol and diesel containing 5 percent biodiesel.
The current rule, as that page states it, requires a 10 percent average carbon-intensity reduction from 2015 levels by 2025, 20 percent by 2030, and 37 percent by 2035. There are separate standards for gasoline, diesel, and alternative jet fuel. Fuels under the standard earn credits. Fuels over it create deficits. Providers balance credits and deficits once a year.
Washington Clean Fuel Standard
The Washington Department of Ecology describes the Clean Fuel Standard on its program page. The standard lowers carbon intensity to 45 percent below 2017 levels by 2038, or to as much as 55 percent below 2017 levels by 2038 if the conditions in the law are met.
Ecology estimates that the program reduced greenhouse-gas emissions by about 3 million tons in 2024, which it says is about the same as taking nearly 700,000 cars off the road, at a cost of less than 1 cent per gallon of gasoline. A fuel below the annual standard generates credits. A fuel above it generates deficits. Utilities may participate. A backstop aggregator can sell residential electric-vehicle charging credits that nobody else claims. Ecology names renewable diesel and ethanol among the fuels that have contributed reductions.
This page does not add credit prices, deficit forecasts, or carbon-intensity tables beyond those two descriptions. Both agencies publish the operating details from the pages linked above.
