Increased levels of environmental awareness and concern are making businesses set and adhere to higher standards of environmentally-responsible operation and remediation than ever before. AT&T's responsibility is considerable because, with 32 manufacturing locations around the world that produce about $12 billion in manufactured products, the company's operations have the potential to make a large environmental footprint. AT&T has aggressively targeted eliminating ozone depleting chlorofluorocarbons (CFCs), reducing the use of other toxic or polluting substances, and also decreasing waste generated by manufacturing operations. This report on environmental technology documents some of the technical work underway both in the environmental R&D organizations at AT&T Bell Laboratories, and in manufacturing facilities, to help us achieve these goals.
