Environment – Material Balance

Overall Environmental Impact

Period: April 1, 2016 - March 31, 2017

Scope of Data Compilation: Mitsubishi Electric Corporation, 109 affiliates in Japan, and 79 overseas affiliates (total of 189 companies)

*
Up to fiscal 2009, the scope of our report was limited to those companies that had drawn up an environmental plan for governance from an environmental conservation perspective. However, under the policy of expanding global environmental management, we have broadened the scope of the report to cover Mitsubishi Electric, its consolidated subsidiaries, and its affiliated companies.

Amount of CO2 emitted during product use (converted value): Sum of CO2 emitted when using 88 finished products targeted for CO2 reduction.
The amount of CO2 emitted is equal to the energy consumed multiplied by the CO2 emissions coefficient, for which the value shown in CO2 Emissions from Fuel Combustion Highlights (2013 Edition) of IEA is used.
*8
Amount of SF6 emitted during product use (corresponding value): Sum of SF6 gas naturally leaked during the operation of products (6) that use SF6 gas for insulation.
Leakage rate used is the value from JEAC5001-2000. Global warming potential value used is from the 2nd Revised Guidelines of the IPCC.
