Clean Fuel Standard data & reports

Carbon intensity data

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

Monthly & quarterly reports

• Monthly credit trading activity report: This report contains the volume of credits traded and the average credit price each month. We'll 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. Past reports are available in our data and reports library. 

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). 
  • 2022 Fuel supply forecast report (the 2022 forecast covers calendar years 2023-2024, which are one compliance period under the CFS rule.) 
    • 2022 Fuel supply forecast (spreadsheet)
  • 2024 Fuel supply forecast report (covering the 2025 compliance period)
  • 2025 Fuel supply forecast report (covering the 2026 compliance period)
• Electric utility reports: Utilities will report to us about their activities investing credit revenue generated by the program. You can read these reports in our Data & reports library.

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

The Clean Fuel Standard statute (RCW 70A.535.0902) requires Ecology, starting in 2025, to report annually to the Legislature on the program’s implementation, including the number of credits and deficits generated by fuel producers and suppliers participating in the program, fuel volumes, greenhouse gas emissions reduced, and average credit prices.

• Clean Fuel Standard Program Progress in 2023

Other 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 May 3, 2022.
