EIAs assess material, chemical and energy use, waste generation, emissions to air, and discharges to water for a manufacturing process. This decision-making tool helps to identify and evaluate potentially adverse environmental effects arising for IBM manufacturing processes as they are developed and as they may be modified over time. Potential environmental consequences are also evaluated within IBM s product design process. IBM eliminated these substances from its manufacturing processes and products at the end of 1993. However, as new and less ozone depleting refrigerants become available, and where feasible, IBM locations are phasing out of CFC-based chillers.
Chillers are close-loop systems.
If maintained properly, only a small percent of a chiller s charge would leak under normal operating conditions. IBM locations are required to maintain their chillers in good condition and preventive maintenance must be conducted. IBM s operations do not release significant quantities of the gases thought to have an effect on global climate change. IBM s greatest potential impact is an indirect one, through the release of carbon dioxide by the utility companies providing the electricity the company uses. IBM s main focus is therefore on energy conservation.
