Direct emissions: emission factors
Direct emission processes: fugitive releases, industrial process and agricultural emissions. From 9 libraries, filed in one model so one publisher's factor compares with another's.
How the 1,086 factors divide
- Fugitive emissions and refrigerants
Fugitive releases of gas to atmosphere, whether or not a refrigerant: refrigerant leakage from cooling equipment, and unintended or vented releases from fuel extraction, processing and distribution.

Who publishes these factors
Each cell counts one library's factors in one subcategory. Library names open the library's page; column heads open the subcategory's.
IPCC publishes the most of these factors (310), then ADEME (271). The most widely published subcategory is Fugitive emissions and refrigerants: 8 of 9 libraries have some.
