Measures to Reduce GHG Emissions: Refrigerants

Refrigerants are substances used in equipment for cooling and heating purposes. Emissions from equipment can be reduced by decreasing the charge size, leak rate, or replacing of the refrigerant with a lower global warming potential (GWP) refrigerant. The refrigerants section includes fact sheets and quantification methods for 7 measures. Use the list below to navigate directly to each measure's factsheet.
