Progress by the electronics industry on protection of stratospheric ozone

In addition to the Montreal Protocol´s controls on CFCs (chlorofluorocarbons), the US Congress has placed an excise tax on chemicals which deplete the ozone layer, based on their ozone depletion potential. It is pointed out that, desiring to protect the stratospheric ozone layer and responding to restrictions placed on CFC production, the electronics industry and their suppliers worldwide have made many important technological breakthrough in eliminating CFC-113 from their manufacturing processes. As a result of industry/government cooperation, CFC-113 may be eliminated faster and at lower financial and business disruption cost than if governments were forced to implement a set of command and control rules. A description of recent progress in this area, both domestic and international, is given
