If the fuel has a carbon intensity value approved by the California Air Resources Board, the fuel producer can apply to DEQ to accept that value with modifications as needed to reflect its destination to Oregon. The fuel producer can submit the application packet sent to CARB and the CARB approval letter. The applicant should also submit an Oregon version of the GREET 3.0 model modified to reflect the transportation mode and distance to Oregon as opposed to California. Fuel producers can submit their fuel pathway applications through the Oregon Fuels Reporting System (see link below).
If the fuel does not have a carbon intensity value from CARB, then the fuel produce can submit their fuel pathway to DEQ for certification. DEQ has developed a series of simplified calculators for well-understood fuel types and a modified version of the GREET model for more complex fuel pathways, available below. Fuel producers can submit their fuel pathway applications through the Oregon Fuels Reporting System.
There are some default carbon intensity values in the rules that can be used for generic fuels such as electricity and fossil natural gas in Table 4 under OAR 340-253-8010.
There are also some temporary values that can be used until a fuel pathway applied for under option 2 is certified in Table 9 under OAR 340-253-8010.

The carbon intensity values for the program are expressed in grams of carbon dioxide equivalent per megajoule of energy (gCO2e/MJ).
