Emissions Inventory

An Emissions Inventory is a list of air pollution sources and the amount of air pollution from each source. Sources can include industrial facilities, cars and trucks, and wildfires. The amount of air pollution is calculated using the best available information. They do not predict or measure the amount of pollution in the air at any given place or time. Measured air pollution is available on the DEQ's Air Quality Index webpage.
