ME 449: Sustainable Air Quality
The purpose of this report is to show how emission inventories are obtained through calculations of emission factors in conjunction with fuel sources.
There are three major contributors to the creation of NOx emissions
To determine the amount of emission you get from a source, you have to take into consideration two factors:
EF * fuel mass = Emission Inventory
The source of the data used is from the EPA AP-42 5th ed. Vols. I (Chapters 1-5, 11) and II (Appendix G).
As for the emission factor rating found in the AP-42, it is how accurate the emission factor for the given source of emission is to the true value. A being very close and E being not.
There are some sources of NOx emissions that are still way too high. Yet there seem to have been remarkable strides in reducing some of these over time. We just need to drive ourselves harder to help fix the problem. If you are not part of the solution, you are part of the problem.
