Previously, Toshiba Group used chlorofluorocarbons (CFCs), trichloroethane, and other ozone-depleting substances as coolants for refrigerators as well as for the cleaning of parts, the dry-etching of semiconductors, and for the forming of heat insulators. Of these, the use of specified CFCs for cleaning was completely discontinued in 1993, and that for inclusion in products in 1995.
On the other hand, Toshiba Group manages air-conditioning systems, fire-extinguishing equipment, and other products that include CFCs and halons by affixing stickers to them stating that they include the substances. CFCs and halons are collected and treated appropriately when the products are no longer used. Currently, 1,950 air conditioning systems and 1,149 fire-extinguishing facilities use CFCs and halons, and the amounts of specified CFCs and halons included in these products are 12 tons and 36 tons, respectively. Toshiba Group treats CFCs and halons properly, though the amount of these substances owned by the Group is increasing due to improved data collection.
