Environmental Data

Environmental Data

The Sumitomo Corporation Group is striving to reduce the environmental impact by promoting to conserve energy and reduce waste at its offices, while making contributions to the environment through its business activities.

In addition, it has expanded the boundary of environmental data on our group from FY2017 to understand the actual environmental situation. The Sumitomo Group will work on environmental improvement through business by the whole group in the future.

The environmental data are assured by KPMG AZSA Sustainability Co., Ltd., an external assurance provider based on International Standard on Assurance Engagements (ISAE) 3000 and ISAE3410.

Please refer to "Independent Assurance Report" for further details about assurance engagement.

  • CO2 emissions from logistics include the transport of cargo within Japan for which Sumitomo Corporation is the cargo owner, and are calculated based on a manual for GHG emissions accounting, reporting, and disclosure systems published by Japan’s Ministry of the Environment and Ministry of Economy, Trade and Industry. Sumitomo Corporation complies with the Act and reduces the use of energy of transportation through promotion of modal shift (utilization of railroads and vessels), optimization of delivery routes and loading on vehicles, promotion of eco-driving, etc. We have set a target of reducing the use of energy from logistics per shipping weight by at least 1% annually in Japan.
  • CO2 emissions from the incineration of waste are calculated by using the CO2 emission factor specified under the Carbon Footprint Communication Program, assuming that all general waste stemming from Sumitomo Corporation’s operations are incinerated.
  • CO2 emissions due to overseas business trips are the emissions from flights departing from and arriving in Japan that Sumitomo Corporation employees took. Business trip destinations are classified into 12 areas and passenger-kilometers are estimated based on the travel distance between Japan and representative airport of each area. CO2 emissions due to overseas business trips are calculated by applying CO2 emission factors published by the UK's Defra to the passenger-kilometers.
  • CO2 emissions from commuting are those from the commuting of Sumitomo Corporation's employees, calculated by using the emissions factors per passenger-kilometer for passenger transport by transport mode published in the Ministry of Land, Infrastructure, Transport and Tourism publication "CO2 Emissions in the Transport Sector."
  • CO2 emissions from downstream leased assets are calculated based on the energy consumption of the buildings that Sumitomo Corporation owns and leases to tenants, using by CO2 emission factors described in the Act on the Rational Use of Energy.
