EGAS Version 5.0

EGAS Version 5.0 is a newly revised tool that can generate emissions growth factors by sector. Growth factors from EGAS 5.0 can be used to project emissions inventories for multiple pollutants. This tool has been drastically revised from EGAS Version 4.0 in a number of ways:

1) Growth factors are now available out to 2035.
2) Growth factors are available by 2- and 3-digit SIC codes, MACT codes, NAICS codes, and SCCs.
3) Tool is available in one executable file and has a simple graphical user interface.
4) Users can customize economic activity datasets to develop growth factors or rely upon default datasets in EGAS 5.0.
5) Growth factors can be generated for the 50 States and D.C. instead of 75 ozone nonattainment areas.
