We track air pollutants, toxics, and greenhouse gas emissions.
Our WEIRS data collection system keeps track of information that facilities with air operating permits must report annually.
Tracking emissions helps us keep Washington's air healthy. To ensure businesses are meeting air quality requirements, we regularly inspect registered sources.
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. Those reporting programs are found in the climate change section of our website.
Some businesses and organizations that are responsible for greenhouse gas emissions are required to report them and in some cases reduce them.
