  • GHG emissions caused by business processes:
    GHG emissions generated by Toshiba Corporation and its group companies in Japan and overseas (Scopes 1 and 2*1) We selected and visited two production sites (Toshiba Corporation Yokkaichi Operations and Hamakawasaki Operations).
  • GHG emissions caused by use of products sold:
    GHG emissions caused by use of products sold by Toshiba Corporation and its group companies in Japan and overseas (Scope 3 Category 11*2)
*1
Scopes 1 and 2: GHG emissions generated by Toshiba through use of fuels and electricity (Scope 1: direct emissions; Scope 2: indirect emissions)

*4
ISAE 3410: International Standard on Assurance Engagements 3410 (assurance engagements on greenhouse gas statements)

Methods of calculation related to the third-party assurance

  • CO2 emissions caused by use of fuels: Calculated based on the Ministry of the Environment's Manual for Calculating and Reporting GHG Emissions (Version 4.1).
  • CO2 emissions coefficient for electricity purchasing: 5.10 t-CO2/10,000 kWh is used as the power factor in Japan for FY2015. GHG Protocol data is used overseas.
  • Greenhouse gases other than CO2: Calculated by using the Global Warming Potential (GWP) in the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).
  • CO2 emissions caused by use of products sold: Calculated by aggregating the emissions estimated to be generated during use of products in the future for the year the products were sold.
