Environment – Managing Chemical Substances

Tracking the Use of 3,208 Controlled Chemical Substances with Our Own Chemical Substance Management System

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 3,208 controlled substances managed by our Chemical Substance Management System, which also incorporates purchasing information for materials and components.

In fiscal 2017, Mitsubishi Electric used 4,203 tons of 141 different chemical substances (4,962 tons of 145 different chemical substances in fiscal 2016), and our Japanese affiliates used 1,401 tons of 41 different chemical substances (1,471 tons of 41 different chemical substances in fiscal 2016). 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.

HFCs: Hydrofluorocarbons
HCFCs: Hydrochlorofluorocarbons
PRTR Law: Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof.
PRTR: Pollutant Release and Transfer Register. A system under which companies track the quantity of substances potentially harmful to human health or the ecosystem which are released into the environment or transferred inside waste material, and report this data to government authorities. The authorities then use these reports and other statistics to produce estimates on release and transfer, and announce them publicly.
