How do welding emissions fit into your emissions inventory?

Sep 07, 2012 · The listed emission factors have a rating, A through D, which indicates the effective confidence in the factor (A indicates the highest confidence). If you think your facility's emissions deviate slightly from the emission factors in AP-42, you'd have a better chance of making a convincing argument over a factor rated D than one rated A.
