Mitsubishi Electric and its affiliates in Japan have been managing chemical substances on a voluntary basis since 1997. The main substances we manage include refrigerant fluorocarbons (HFCs*1 and HCFCs*2), volatile organic compounds (VOCs), and the 10 substances designated under RoHS. Together with 462 substances designated under the revised PRTR Law*3 (PRTR*4) that came into force in November 2009, there are currently 3,264 controlled substances managed by our Chemical Substance Management System, which also incorporates purchasing information for materials and components.
In fiscal 2018, Mitsubishi Electric used 4,592 tons of 141 different chemical substances (4,116 tons of 141 different chemical substances in fiscal 2017), and our Japanese affiliates used 1,482 tons of 41 different chemical substances (1,376 tons of 41 different chemical substances in fiscal 2017). Details on the release and transfer of these substances are shown in the figure below. We will continue to track and manage our use of these substances, and eliminate any unnecessary use.
