Clean Fuel Standard requirements for participation

Complying with the Clean Fuel Standard (CFS) includes registering with Ecology, reporting fuel sales, paying an annual fee, and purchasing credits if you’re a deficit holder.

Under the CFS, high-carbon fuels generate deficits. Producers and suppliers of these “regulated” fuels must comply with the CFS, including registering with Ecology and reporting fuel sales.

Producers and suppliers of low-carbon or “opt-in” fuels can choose to comply with the CFS in order to generate credits.

Certain high-carbon fuels do not generate deficits under the CFS. But producers and suppliers of these “exempt” fuels can also choose to comply and generate credits.

Who needs to register

Producers and suppliers of regulated fuels to Washington consumers must participate and register in the Washington Fuels Reporting System (WFRS). Regulated fuels include:

Gasoline
Diesel
Ethanol and blends
Biomass-based diesel and blends
Fossil compressed natural gas (CNG)
Liquid natural gas (LNG)
Liquid-compressed natural gas (L-CNG)
Fossil Propane, liquefied petroleum gas
Hydrogen, compressed or liquefied
Any other liquid or non-liquid fuel

Producers of low-carbon fuels may participate. If they do, they’ll need to register. Low-carbon fuels include:

Electricity
Bio-CNG, bio-LNG, or bio-L-CNG
Alternative jet fuel
Renewable propane

Producers selling non-exempt and exempt fuels must also report the exempt fuels, but reporting exempt fuels will not generate deficits. Producers of low-carbon versions of these fuels may opt-in to generate credits. Exempt fuels include:

Aviation fuel
Marine fuel
Railroad fuel
Offroad fuel used for agriculture, logging, mining, and other uses

Refer to our guidance: Participant Guidance on Documenting Exempt Fuels: Clean Fuel Standard Program Guidance

Registration and getting started

To participate, you need to register through the Washington Fuels Reporting System (WFRS). This system manages:

Fuel pathway certification
Fuel transactions
Credit generation and transfers

To register

Follow the step-by-step user guide in the guidance document library.
Sign up for a Secure Access Washington (SAW) account.
Log into SAW, add the Climate Portal to your list of services, and create a profile.
After approval, access WFRS through the Climate Portal.

Account approval

Your account must be approved before you can access WFRS. After submitting your registration, you will receive a phone call from Ecology staff to finalize the process.

Public registered parties list

Read the current list of registered parties.

Reporting and compliance

Regulated and opt-in participants must:

Register to produce or import fuel in Washington.
Keep records of each fuel transaction.
Submit quarterly and annual reports through WFRS.

Quarterly reporting deadlines

Q1: Due June 30
Q2: Due Sept. 30
Q3: Due Jan. 10
Q4: Due March 31

When to expect credits

You must be registered, and your account must be approved before credits can be claimed. Credits are designated based on quarterly reports being submitted and, when necessary, reconciled with business partners.

Use the Clean Fuel Standard Obligation Calculator to estimate the number of credits or deficits you may generate in the program. This calculator is a tool for estimation only. It does not change any individual entity's obligations under the Clean Fuel Standard.

Annual Reporting

Each reporting party must submit an Annual Report on WFRS summarizing the four quarterly reports from that year and attesting to their accuracy. Annual Reports must meet the requirements outlined in WAC 173-424-430.

Instructions on submitting an annual report can be found in Section 6 of the WFRS-CBTS User Guide.

Annual Report deadline

Reporting opens: April 1 each year

Submission deadline: April 30 each year

Prerequisites: All previous quarterly and annual reports must be submitted. The status for each Quarterly Report must be either:

The initial submission
Corrections that have been approved by Ecology

Learn more about Washington’s Clean Fuel Standard (CFS) and the 2024 guidance for electric utilities on using revenue from residential EV charging credits.

To begin your Annual Report, follow these steps:

Log in to WFRS as a Contributor or Administrator.
Click the "CFS Reports" tab in the navigation bar.
Scroll to the bottom and select "View Annual Reports."
Find the reporting year and click "Go to Annual Report."
Review the summary of all quarterly reports. Click "Go to Details" on any fuel type to return to Quarterly Reports, if needed.

At the bottom of the Annual Report page, you will find the Annual Summary, which includes:

Credit and deficit balances for the reporting year.
Automatic credit retirement calculations for compliance purposes.
Final accounting of credits and deficits carried over to the next year.
An option to pledge credits toward that year's Credit Clearance Market.

Note: The credit and deficit values in the Annual Summary might not always match the totals from the four Quarterly Report sections. This is because Quarterly Reports do not account for retroactive credit or deficit adjustments. Refer to the Ledger rather than the Quarterly Reports for the most accurate comparison.

Before submitting, you must check the box confirming the accuracy of your Annual Report.
If you need to upload a document or add a comment without submitting, click "Save Annual Report."
If applicable, upload any required documents, such as the MCON report, if it must be reuploaded for the Annual Report.
When ready, click "Submit Annual Report."

Important

Only users with Administrator or Signatory Authority roles can submit the Annual Report.
Once submitted, your credit and deficit balance will be updated in the Ledger tab.

Credits and compliance

Credits can be used to meet compliance obligations. For example, credits bought in any year can cover deficits in the current compliance period.

Credit Clearance Market requirements and pricing

WAC 173-424-570(2) requires Ecology to publish the maximum price for the Credit Clearance Market (CCM) by the first Monday of April each year. If a CCM becomes necessary in 2025, the maximum price for credits will be $251.94 per credit.

Please note that while the maximum price has been set, we will not know whether a Credit Clearance Market will be required until May 15. The market will only take place if there are regulated parties with unmet compliance obligations from the prior compliance period. If a CCM is held, it will run from June 1 to July 31.

For more information on 2025 CCM participation and credit pricing, see the Credit Clearance Market Participation and Price Notice.

Note on automatic credit retirement

The rules for credit retirement will be outlined in our guidance. Credits do not expire and can be bought, sold, and used for compliance at any time.

You can find more information on this subject in WAC 173-424-510(6) and (7).

Program fee

Program participants must pay a fee to cover the cost of program administration.

Fees are based on the program budget, and participants will be invoiced each year.
