Ozone depletion potential of estimated emissions18

HP facilities use ozone-depleting substances (ODSs) in cooling and air conditioning systems. Although these systems are sealed, leaks during operation and maintenance could result in emissions. We continue to replace chlorofluorocarbons (CFCs) in our systems with hydrofluorocarbons (HFCs). Although HFCs are greenhouse gases, they do not deplete the ozone layer. We are also starting to replace HFC-based cooling systems with HFC-free equivalents when they reach the end of their operational lives. These are not ODSs and have no or very low global warming potential. We do not measure ODS emissions but rather estimate leakage using guidance from the Intergovernmental Panel on Climate Change.
