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, the boundary of environmental data has been expanded to Joint operations from FY2020 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 marked with a star (★) for FY2020 results 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.

<Boundary of the Data>

Non-consolidated : Head office, regional offices, branches and sub-branches in Japan and overseas
Consolidated : Non-consolidated, Consolidated subsidiaries, Joint operations
* As of the end of March of the reporting period
* For Joint operations, the amount equivalent to the investment ratio as of the end of March of the reporting period is included in the environmental data.
* One site of the Joint operations is excluded from the scope of FY2020 because its data collection system is not in place yet.

The detailed boundary of each data are as follows.

  • CO2 emission factors for electricity:

    (Non-consolidated in Japan) The basic emission coefficients of individual power companies.
    (Consolidated subsidiaries in Japan) The average emission coefficient of all power companies.
    (Overseas) Emission factors from electricity generation are based on the country-specific data in 2013 listed on "CO2 EMISSIONS FROM FUEL COMBUSTION 2016 EDITION", an IEA (International Energy Agency) statistics.

  • CO2 emission factors other than those from electricity generation are 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.
  • Group companies emitting more than 3,000 t-CO2e for each gas per year are subject to the aggregation of Scope1<other GHGs>, under the Greenhouse Gas Emissions Accounting, Reporting, and Disclosure System in Japan.

    In FY2018 and FY2019, we aggregated non-consolidated and consolidated subsidiaries in Japan and the scope of Scope1<other GHGs> was expanded to consolidated (excluding Joint operations) in FY2020.

  • Scope1 <other GHGs> 4,210 t-CO2e in FY2020 was derived from Dinitrogen monoxide (N2O).
  • The main reason for the increase of GHG emissions in FY2020 compared to FY2019 is the addition of Joint operations to the boundary of data.
  • The CO2 emissions from Joint operation in the power generation business are included in the FY2019 results, which is the base year of Sumitomo Corporation Group's carbon neutrality, and FY2020 results in the ESG Communication Book -Our Climate Change Initiatives-.
    The scope of Sumitomo Corporation Group's carbon neutrality includes the following in addition to the GHG emissions above;

    Scope1,2: Direct CO2 emissions from Sumitomo Corporation's affiliated companies under the equity method for power generation businesses, as well as indirect CO2 emissions from the generation of energy used by those companies.

    Scope3: Indirect CO2 emissions associated with the use of energy resources produced by fossil energy concession of Sumitomo Corporation Group, its subsidiaries, and affiliated companies under the equity method.

  • We couldn't collect the environmental data for 38 sites due to COVID-19 lockdown or working from home in FY2019. In FY2018, GHG emissions of these sites were equivalent to about 5.2% of the total GHG emissions.

  • GHG 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.
  • GHG emissions from waste are calculated from all general waste of Sumitomo Corporation.
    Up to FY2018, emissions were calculated using emission intensity for incineration treatment published by the Carbon Footprint Communication Program. The results after FY2019 were calculated using the emission intensity for each type of waste, which is published in the emission intensity database for calculating greenhouse gas emissions and other emissions by organizations throughout the supply chain. The calculation of GHG emissions for FY2020 uses the emission intensity database Ver.3.1.
  • GHG 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. GHG emissions due to overseas business trips are calculated by applying CO2 emission factors published by the UK's Defra to the passenger-kilometers.
  • GHG emissions from commuting are those from the commuting of Sumitomo Corporation's employees working in Japan, 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."
  • GHG emissions from downstream leased assets are those from 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 in Japan.
  • GHG emissions (the above Scope1, 2 and Scope3) were 1,641,079t-CO2e/1,537,072t-CO2e/2,213,716t-CO2e in FY2018, FY2019, and FY2020 respectively.
