What is an emissions inventory?
Air Pollutants
The “criteria” air pollutants
Two forms of particulate matter – burning and dust
Carbon monoxide – burning fuel
Lead – leaded gasoline
Nitrogen dioxide - burning
Ozone – burning and chemical reactions
Sulfur dioxide - burning

What is an Emissions Inventory
A full list, by source,
of air pollutant emissions
for a specific place and time
Uses for Emissions Inventory Data
Identify important sources and impacts of air pollution
Collect baseline data
Look at trends in pollution
Look at how air control programs impact emissions
Air quality planning
Predict changes in air quality
Look at local and regional sources of air pollution
Uses for Emissions Inventory Data (cont.)
Air quality management tool
Air quality modeling & impact
assessments
Allows local data to be considered in
larger scale analyses related to
regulations development
