Fiscal 2019 environmental data

Environmental Accounting

Scope and Period of Data Compilation and Basis of Calculation

Scope and Period of Data Compilation

  • Period: April 1, 2018 - March 31, 2019
  • Scope of Data Compilation: Mitsubishi Electric Corporation and major affiliates (Japan and overseas)
  • * The scope of data compilation is the same as the scope of this Environmental Report.

Basis of Calculation

Data is calculated for environmental conservation costs, environmental conservation benefits (environmental performance), and economic benefits from environmental conservation activities (actual profit or cost-saving benefits) in accordance with the Environmental Accounting Guidelines (2005 edition) issued by the Japanese Ministry of the Environment. Economic benefits are aggregated as actual benefits, which consist of earnings and savings, estimated benefits based on Mitsubishi Electric Group accounting standards, including economic benefits to customers of using our products, such as lower electricity bills, and environmental improvements achieved outside our business sites.

  • * Environmental conservation costs are aggregated as straight-line depreciation for capital investments made over the past five years and are assumed to have useful lives of five years. The annual benefits of earnings and savings attributable to capital investments are also assumed to have resulted from investments over the past five years.
  • * In the case of comparisons to the previous year, the previous year's data have also been revised to reflect changes in the scope/range of data.
