Climate Commitment Act emissions reporting

In Washington, businesses that emit more than 10,000 metric tons of CO2 equivalent per year are required to report their emissions to our Greenhouse Gas (GHG) Reporting Program. The Climate Commitment Act (CCA) builds off of this existing reporting framework, but also has specific emissions reporting requirements unique to the cap-and-invest program.

Trainings available!

Registration is now open for our emissions reporting training for businesses that supply fuels other than natural gas, such as gasoline, diesel, and propane.

Reporting emissions

Under the CCA, all businesses covered by the cap-and-invest program must report their emissions so that we can track program compliance and emissions-reduction progress over time.

In addition, the Legislature designated three business types — natural gas utilities, electric utilities, and 'emissions-intensive, trade-exposed' entities (EITEs) — that receive some of their emissions allowances for free. These businesses must report additional information so that we can determine the number of no cost allowances they should receive. We will provide trainings for entities that need to submit specialized information.

CCA reporting deadlines

In our current rulemaking, we are proposing a series of reporting deadlines that will enable us to analyze the reported data, provide no cost allowances, and track businesses' compliance obligations in a timely manner — keeping Washington on track acheive total carbon neutrality by 2050.

Emissions reporting trainings

In order to help covered businesses participate effectively in the cap-and-invest program, we are providing a series of trainings aimed at specific business types that need to submit reports in addition to what is required under the GHG Reporting Program.

Timely and accurate emissions reporting is a critical part of fulfilling a business's cap-and-invest compliance obligation, so we strongly encourage anyone with covered emissions to participate in the relevant trainings.

We are working to schedule emissions reporting trainings for electric power entities, facilities, and third-party emissions verification experts. Information about how to register for these trainings will be posted once available.

Click the Past Trainings tab, to the right, for information about the recent trainings we held for EITEs and fuel suppliers.


In August, we hosted an emissions reporting training for EITEs. Industries that fall into this category are outlined in the CCA, and include oil refineries, pulp and paper mills, and large manufacturers.

Fuel suppliers

In September, we held a training for businesses participating in the cap-and-invest program that supply fuels other than natural gas, such as gasoline, diesel, and propane.
