Statewide Emissions Inventories

The following links contain inventories developed for statewide criteria and hazardous air pollutants.

If comparing inventories, the reader should note that emission estimation methods and emission factors are continually changing and improving, which may cause emissions to appear higher or lower from one year to the next without any actual emission change. In addition, the application of new pollution controls will change emissions at a source and should be accounted for when comparing emissions from different years. Finally, between inventories, EPA adds source categories and others may be consolidated. If comparing data between years and you have questions, please contact for clarification
