State agency greenhouse gas reporting
Washington is dedicated to reducing greenhouse gas emissions to help slow the impacts of climate change. State agencies are joining the effort. With direction from the Legislature, state agencies are working with us to monitor and reduce their emissions.
State Agency Emission Limits
In 2020, the Legislature and Governor updated the state agency emission limits, codified in RCW 70A.45.050. The emissions reporting program is a critical part of Washington state's efforts to meet greenhouse gas emissions limits for state agencies:
- 15% below 2005 levels by 2020
- 45% below 2005 levels by 2030
- 70% below 2005 levels by 2040
- 95% below 2005 levels by 2050; achieve net zero
To track state agencies’ progress toward meeting these limits, each covered agency must report the following:
- Every year
- Estimate emissions using emissions calculator.
- Even-numbered years
- Report to the State Efficiency and Environmental Performance (SEEP) office at the Department of Commerce
- Actions taken over the last biennium to meet these emission-reduction targets.
- Actions planned for the next two biennia to meet emission limits.
- Long-term strategy for meeting the emission limits.
- Report to the State Efficiency and Environmental Performance (SEEP) office at the Department of Commerce
- Odd-numbered years
- State agencies will submit progress reports to SEEP.
Legislative reports
Each biennium, we collaborate with SEEP to publish a progress report to the Legislature.

Emissions reporting instructions and training
We're responsible for collecting emissions data. SEEP is responsible for working with state agencies on emission-reduction strategies. Our two agencies collaborate to combine reporting requirements, and we have resources below to simplify the process.
The updated emissions calculator and SEEP greenhouse gas reduction strategy web-form are now available. Since 2025 is an odd-numbered reporting year, the SEEP strategy report for emissions reduction is less comprehensive than last year. 2025 reporting of calendar year 2024 data is due by May 30, 2025.
Instructions
- Complete the SEEP greenhouse gas reduction strategy web-form.
- Complete the greenhouse gas emissions calculator. The DES leased and permanently assigned vehicle fuel use by agency is now included as a tab in the emissions calculator. Reference this reporting instructions document.
- Create a Secure Access WA (SAW) account. Reference this guidance document for setting up a SAW account, if needed.
- Once your SAW account is active, follow the greenhouse gas emissions reporting instructions to upload the emissions calculator and any supporting documents to the SAGE application (login required).
Trainings
The following trainings are available. Please note that these trainings are only for state agency greenhouse gas emissions and strategy reporting and aren't relevant to other Ecology emissions reporting programs.
- Gathering Data, recorded Feb. 9, 2022
- Completing the Calculator, recorded March 20, 2024
- Completing the Emission Reduction Strategy Web-form, recorded April 17, 2024
Questions?
- For questions about emission-reduction strategies, contact the SEEP office.
- For questions about the emissions calculator or uploading documents to the SAGE application through your SAW account (login required), email CPRsage@ecy.wa.gov.
Other required greenhouse gas reports
Some agencies emit larger amounts of greenhouse gases and have additional reporting requirements to EPA and us. Visit EPA's greenhouse gas program to determine if your agency is required to report under federal requirements and visit our facilities greenhouse gas reporting page to check for additional state reporting requirements.
