Ozone depleting substances in ancillary equipment
We use ozone depleting substances (ODSs) primarily in cooling systems. We have switched to using hydrofluorocarbons (HFCs) in some ancillary equipment. HFCs do not deplete the ozone layer but do contribute to global warming.ODSs - mainly HCFCs - are sealed inside cooling systems and are only released in the event of a leak or during maintenance.
We plan to establish a team in 2005 to develop a business strategy to eliminate ancillary emissions of ODSs. This will closely monitor equipment and put in place recommendations on alternative refrigerants and new equipment.

Total ozone depletion potential from ancillary use did not change from 2003 (but decreased by 61.0% since 2001). Ozone depletion potential from ancillary use per unit sales increased by 8.8% since 2003 (but decreased by 60.5% since 2001).
The current trend indicates that we may miss our 2005 target to eliminate ozone depleting emissions from ancillary use. It has not proved possible to eliminate all emissions during servicing and maintenance of cooling equipment. This means that we need to upgrade or replace equipment to use non-ozone depleting gases. New cooling systems are being introduced - which don’t use ozone depleting gases. However, we will not have upgraded or replaced all equipment by 2005.
