Climate change emissions reporting

Washington has several greenhouse gas reporting programs that help us track our state’s emissions. We require businesses who emit at least 10,000 metric tons of carbon pollution annually and all state agencies to report their greenhouse gas emissions.

Washington's greenhouse gas reporting programs

Climate change is likely the defining environmental issue of our time. Reducing greenhouse gas pollution is vital to protect air, water, food sources, and the economy.

Protecting Washington from the effects of a rising global temperature is not a new endeavor for Washington. In 2008, the Legislature required the state to reduce greenhouse gases significantly by 2050 to address climate change.
 

Who reports greenhouse gases

Type of organization Annual greenhouse gas emissions
(Metric tons CO2e)
Required greenhouse gas reporting programs
Washington state agencies and state universities/colleges Under 10,000 Washington state agency reporting program
Washington state agencies and state universities/colleges 10,000 or more Washington state agency reporting program and Ecology's mandatory reporting program
Industrial facilities and transportation fuel suppliers Under 10,000 No greenhouse gas reporting required
Industrial facilities and transportation fuel suppliers 10,000 or more Ecology's mandatory reporting program

Greenhouse gas reporting program

We've been collecting greenhouse gas emissions from companies since 2012. Our mandatory greenhouse gas reporting requirement applies to:

  • Facilities who annually pollute at least 10,000 metric tons of greenhouse gasses in Washington.
  • Suppliers of liquid motor vehicle fuel, special fuel, and aircraft fuel that supply products equivalent to at least 10,000 metric tons of carbon dioxide in Washington.

State agency greenhouse gas reporting program

The State Agency Climate Leadership Act established greenhouse gas emission reduction limits for Washington state agencies. To track our progress, state agencies are required to report their GHG emissions annually through the Washington state agency greenhouse gas reporting program. They're also required to report actions taken to reduce their emissions.
