Since eliminating ozone-depleting substances (ODS) from HP manufacturing in 1993, we use ODS at HP facilities only in cooling and air conditioning systems. Although these systems are sealed, leaks during operation and maintenance can result in emissions. HP continues to reduce the ozone-depleting potential of its cooling and air conditioning systems by replacing chlorofluorocarbons (CFCs) with hydrofluorocarbons (HFCs). HFCs do not deplete ozone but are greenhouse gases.
We do not measure ODS emissions but estimate leakage using information from the Third Assessment Report published by the Intergovernmental Panel on Climate Change. We estimate that our ODS releases increased in 2007 compared with 2006. We have improved the accuracy of our ODS calculations through enhanced reporting methods.
