The HCFC–22 tool provides two different methods for calculating HFC-23 emissions from HCFC-22 production. One requires data on the flow rate and composition of the HFC-23 exit streams. The other requires data on the amount of HCFC-22 that has been produced. Both allow the emissions reductions associated with the use of emissions control technologies to be calculated.

HCFC-22 plants have other greenhouse gas sources, such as the fuels used in energy production. All sources that are typically associated with an HCFC-22 plant are listed below
