Greenhouse Gas Calculation Tools
This site contains downloadable spreadsheets and links to other approved
calculation tool sites to assist with calculations for greenhouse gas
emissions. Some companies may need to apply more than one calculation
tool to cover their greenhouse gas sources, and facilities should choose
all appropriate tools. All calculation tools are Microsoft
Excel Workbooks unless otherwise noted.

DEP - Greenhouse Gas Worksheet
This Excel spreadsheet is designed for all types facilities. It
contains a combustion worksheet, revised DEP-recommended emission factors,
and a sheet to help calculate emissions of refrigerants. This
spreadsheet replaces the Small Combustion Worksheet and the Expanded
Combustion Worksheet.

WebFIRE
http://cfpub.epa.gov/oarweb/index.cfm?action=fire.main
The Factor Information Retrieval (FIRE) Data System is a database containing
more than 17,000 AP-42-rated factors, as well as approximately 4,400
unrated emissions factors that EPA recommends for use. U.S. EPA has
converted the existing database program (version 6.25) to a web-based
application (WebFIRE) to allow easier public access and for FIRE to
be updated more frequently. You can search for available emission
factors by SCC or by simple phrase.
