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 foaming 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 continues to use CFCs and halons by affixing stickers to air-conditioners, fire-extinguishing equipment, and other products that include these substances stating that they include the substances and thus ensuring their proper management. CFCs and halons are collected and treated appropriately when the products are no longer used. Currently, 1,775 air-conditioning systems and 848 fire extinguishers and fire-extinguishing facilities use CFCs and halons, and the amounts of CFCs and halons included in these products are 15 tons and 27 tons, respectively. These amounts are decreasing each year through appropriate treatment. In FY2008, Toshiba Group collected 4.4 tons of CFCs and 4.4 tons of halons.
