Air quality emissions reporting
If your business creates air pollution, you are likely regulated by us or your local clean air agency, and have to report your emissions.
Washington Emissions Inventory Reporting System
Facilities with an air operating permit must send us, or their local clean air agency, their emissions data through the Washington Emissions Inventory Reporting System (WEIRS).
Annual air quality registration
Most sources of industrial air pollution are required to register with us, report their emissions, and pay a yearly fee based on the amount of air pollution they emit.
Greenhouse gas emissions
Washington requires some industrial facilities, businesses, and transportation fuel suppliers to annually report their greenhouse gas emissions. We use these reports to better understand the amount and sources of carbon pollution in Washington.
