State agency greenhouse gas reporting

Washington state leads by example in reducing carbon pollution from government facilities, fleets, and operations. We provide support and tools to help state agencies accomplish this. We also collect agency emissions data and provide a progress report to the Legislature every two years. Learn here how agencies calculate and report carbon pollution.

State Agency Climate Leadership Act

The State Agency Climate Leadership Act (RCW 70.235.050 and 060) requires state agencies to reduce their greenhouse gas emissions. It applies to some state agencies in Washington, including colleges and universities. Agencies must reduce carbon pollution below 2005 levels:

  • 15 percent by 2020.
  • 36 percent by 2035.
  • 57.5 percent by 2050, or 70 percent below expected emissions that year.

Changes to the reporting program

Starting with the 2016 report, we updated the tools and requirements for state agency greenhouse gas reporting. There are new reporting thresholds, which means some agencies no longer need to report their emissions. Check the list to see if your agency is required to report. The new reporting deadline is July 1. Watch the video on this page to learn more about the program changes and how they will affect your agency.

Tools for reporting your emissions

Agencies should use the tools below for calculating and reporting:

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 you are required to report to them and visit our facilities greenhouse gas reporting page to check for additional reporting requirements.
