Emission Estimation Calculators - Booklet 1

These downloadable spreadsheet calculators were designed to assist with estimating the releases of National Pollutant Release Inventory (NPRI) substances from a variety of common operations or processes. The tools are focused on releases to air and are based primarily on default emission factors, however they can be adapted for the use of site-specific emission factors where these exist.

Since NPRI reporting thresholds are for the facility as a whole, the air releases calculated using these tools will need to be combined with releases from other sources and activities at the facility where applicable.
