Clean Fuel Standard program documents

Monthly Credit Transaction Reports

These reports contain the volume of credits traded and the average credit price. We will post the most recent monthly report after the previous month's transactions. Previous months can be found below under 'Documents'.

Quarterly Data Summary

These reports provide 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.

Annual Cost Estimates

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