Toshiba Group proactively installed systems to collect and/or remove sulfur hexafluoride (SF6), which is used to insulate heavy electric machinery, and perfluorocarbons (PFCs), which are used to produce semiconductors. As a result, in FY2000, the Group nearly halved the total amount of GHG emitted* compared to the FY1990 level, and in subsequent years, GHG emissions continued to decrease as the Group steadily took measures to improve its production processes.Meanwhile, energy-derived CO2 emissions resulting from the use of electricity, which peaked in FY2007, when production reached its highest level, have been reduced since FY2008 by taking energy conservation measures at all business and production sites, including ones overseas, restructuring production sites, and introducing renewable energy proactively
