Oregon Clean Fuels Program

Clean Fuel Standards

The current version of the Clean Fuels Program's regulation can be found on the Secretary of State's website.

The clean fuel standards are the annual average carbon intensity that a regulated party must comply with. There is a standard for gasoline and gasoline substitutes and one for diesel and diesel substitutes. The baseline year for the program is 2015 and represents 10 percent ethanol blended with gasoline and 5 percent biodiesel blended with diesel. The rule requires a 10 percent reduction in average carbon intensity from 2015 levels by 2025. Tables 1 and 2 at the end of OAR 340-253 contain these values and are shown here:


​​Clean Fuel Standards (gCO2e/MJ) ​ ​ ​ ​ ​ ​ ​ ​ ​
​2016 2017​ 2018​ 2019​ ​2020 2021​ ​2022 ​2023 2024​ 2025​
​% reduction ​0.25 ​0.50 ​1.00 ​1.50 ​2.50 ​3.50 ​5.00 ​6.50 ​8.00 ​10.00
​Gasoline ​98.37 ​98.13 ​97.66 ​96.59 ​95.61 ​94.63 ​93.15 ​91.68 ​90.21 ​88.25
​Diesel ​99.39 ​99.14 ​98.61 ​97.26 ​96.27 ​95.29 ​93.81 ​92.32 ​90.84 ​88.87

Deficits and Credits

Deficits are generated when the carbon intensity of a specific fuel exceeds the clean fuel standard in a given year. Credits are generated when the carbon intensity of a specific fuel is lower than the clean fuel standard in a given year. 

Regulated parties
in the Clean Fuels Program are importers of gasoline, diesel, ethanol and biodiesel. An “importer” is the entity who has ownership title to a transportation fuel from locations outside of Oregon at the time it is brought into the State of Oregon. Businesses that produce ethanol and biodiesel in Oregon are also regulated parties. Regulated parties must comply with all of the regulations for the Clean Fuels Program.

Small importers are businesses that import less than 500,000 gallons of transportation fuels per year. Small importers do not have to comply with the Clean Fuel Standards. Small importers have the option of submitting their annual compliance report through the EZ-Fuels Online Reporting Tool for Fuel Distributors.


Fuels used in the following applications are exempt from the regulations: aircraft, construction equipment, farm tractors, farm vehicles, implements of husbandry, locomotives, log trucks, military tactical vehicles and tactical support equipment, racing activity vehicles and watercraft.

Credit generators are providers of clean fuels – fuels whose carbon intensity is lower than the standard for the gasoline or diesel they substitute for. Credit generators are not required to participate but can choose to voluntarily participate by registering with the program if they want to generate credits. Examples include businesses that own electric vehicle charging stations, dispensers for propane, producers of biogas, electric utilities and transit agencies.

Requirements for regulated parties and credit generators:

Collectively, regulated parties and credit generators who opt into the program are referred to as Registered Parties and must:

  • Register with DEQ before producing fuel in Oregon, importing fuel into Oregon or generating or transacting credits for fuels supplied in Oregon;
  • Keep records for each transaction of transportation fuel imported, sold or supplied for use in Oregon; and
  • Submit quarterly annual reports using the DEQ-administered Oregon Fuels Reporting System.

Demonstrating compliance

Regulated parties must initially comply with the Clean Fuel Standards by balancing their credits and deficits for 2016 and 2017 by the end of the 2017 calendar year. Starting in 2018 regulated parties must comply yearly by the end of each calendar year. Regulated parties can retire credits they generated themselves or purchase credits from other entities. A new Credit Clearance Market will provide an additional opportunity for regulated parties to comply with the clean fuel standards if they cannot generate or purchase sufficient credits during the year.
