Clean Fuel Standard data & reports

Carbon intensity data

• Carbon intensity value(s) and its associated fuel pathway code(s) for approved applications

Monthly and quarterly reports

• Monthly credit trading activity report — This report contains the volume of credits traded and the average credit price each month. We will post the most recent monthly report after the previous month's transactions.
• Quarterly data summary — This report provides an overview of the volumes and types of fuels participating in the program. It also includes the number of deficits and credits generated by fuels, based on quarterly data submitted by registered parties. After each quarter, we will post a summary of the data:
  • Quarter 1 - 2023 report.
  • Quarter 2 - 2023 report
  • Quarter 2 - 2023 report, table format 

Annual reports

• Fuel supply forecast — We and the Washington Department of Commerce are directed to develop "a periodic fuel supply forecast to project the availability of fuels to Washington necessary for compliance with clean fuels program requirements” (RCW 70A.535.100). Commerce contracted with Berkeley Research Group to perform the 2022 forecast (released Sept. 30, 2022).
  • Fuel supply forecast report.
  • Fuel supply forecast (spreadsheet).
• Electric utility reports — Utilities will report to us about their activities spending credit revenue generated by the program.

Annual estimated costs and cost-savings of the Clean Fuel Standard

WAC 173-424-710(5) requires the Department of Ecology to estimate the total greenhouse gas emissions reductions and the average cost or cost savings per gallon of gasoline or diesel attributable to the Clean Fuel Standard each year.

Estimates are available in the ‘Annual Cost Estimates’ section of our Data & Reports library.

Other reports

• Independent cost-benefit analysis (released July 1, 2022) — As part of the Clean Fuel Standard law, we were directed by the Legislature to hire an independent contractor to analyze “the best estimate or range in probable costs or cost savings attributable to the clean fuels program per gallon of gasoline and per gallon of diesel.”  We held an online information session about the preliminary results on May 3, 2022.
