Reporting for the Clean Air Rule

In March 2018, Thurston County Superior Court ruled that parts of the Clean Air Rule are invalid. The Superior Court's ruling prevents us from implementing the Clean Air Rule regulations that cap and gradually reduce major sources of carbon pollution. This means that compliance with the rule currently is suspended. On May 14, 2018 we published a media release and filed an appeal with the Washington State Supreme Court.

Under a separate Ecology rule, facilities covered by the Clean Air Rule still are required to report their emissions for the Greenhouse Gas Reporting program.

Businesses covered by the Clean Air Rule are required to submit two reports to us. One is a greenhouse gas report and the other is a compliance report.

Clean Air Rule reports

Businesses covered by the Clean Air Rule must report their greenhouse gas emissions reductions every three years. Reductions are entered into our Clean Air Rule Tracking System and must be verified by an approved third party.

In addition to reporting reductions, businesses are required to report their annual greenhouse gas emissions. Businesses that are covered by the Clean Air Rule are also required to have their greenhouse gas emissions report verified by an approved third party.

Greenhouse gas report

Many businesses were already required to submit an annual greenhouse gas report, although now businesses covered by the Clean Air Rule must get these reports verified by a third party. To learn more about these reports visit the greenhouse gas reporting page.

Compliance report

Compliance reports for the Clean Air Rule show the actions taken by businesses to reduce greenhouse gases and meet the rule requirements. Reports contain information about emission reduction units that are generated, obtained, used, traded, sold, or banked. Verification by a third party is also part of the reporting process. These third-parties determine if reductions have permanently reduced emissions and are accurate.

Steps for submitting a compliance report

Compliance reports need to be entered in the Clean Air Rule Tracking System (CARTS). Steps for reporting are:

  1. Secure Access Washington: Sign in through your existing Secure Access Washington (SAW) account or create a new one.
  2. Request access: Request access to the Air Quality Application Portal. See the air quality portal user guide for more information.
    • Select “add a new service”
    • Choose “Department of Ecology”
    • Find “Air Quality Application Portal” on the list and click “Apply”
  3. Register: You will need to go into the portal to register with CARTS. Within five business days you will receive an email from Ecology confirming your registration.
  4. Enter your reductions: After you receive the confirmation email, you can access CARTS and begin entering your reduction information. See the CARTS user guide for more information.

CAR report deadlines for the first compliance period

Energy-Intensive, trade-exposed (EITE) businesses do not enter the program until 2020. Visit the EITE webpage for more information.
