Air Emissions Inventories

Air Emissions Inventory Tools

The Bridge Tools (Facility/Point, Nonpoint/Onroad/Nonroad, and Event) are available to State/Local/Tribal agencies for reporting NEI datasets to the Emissions Inventory System. The bridge tools create XML datasets from Access database templates. Data can also be imported from the XML format into these Access templates. The remaining links are other tools used to develop the NEI.
