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 (Scope1, 2) (t-CO2)

• For the breakdown of CO2 emissions, Scope1 emissions were 64,859t-CO2/934,276t-CO2/939,346t-CO2 and Scope2 emissions were 252,869t-CO2/ 752,378t-CO2/630,412t-CO2 in FY2016, FY2017, and FY2018 respectively.
• We revised FY2016, FY2017 and FY2018 figures after reviewing the boundary of the data for more accurate description. （Data prior to revision: FY2016: Consolidated subsidiaries 806,490t-CO2, Total 811,679t-CO2, Scope1 558,811t-CO2, FY2017: Consolidated subsidiaries 2,095,089t-CO2, Total 2,100,015t-CO2, Scope1 1,347,637t-CO2, FY2018: Consolidated subsidiaries 2,073,552t-CO2, Total 2,077,700t-CO2, Scope1 1,447,288t-CO2. There is no data revision of Scope2 in which fiscal year. ）

• CO2 emission factors for electricity:
  (Non-consolidated in Japan) The basic emission coefficients of individual power companies. Up to FY2015, the average emission coefficient of all power companies.
  (Direct and Indirect 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.

CO2 Emissions (Scope3) (t-CO2)

• CO2 emissions (the above Scope1, 2 and Scope3) were 387,575t-CO2/1,760,634t-CO2/1,641,079t-CO2 in FY2016, FY2017, and FY2018 respectively.
• We revised FY2016, FY2017 and FY2018 figures after reviewing the boundary of the data for more accurate description. （Data prior to revision: FY2016 CO2 emissions (the above Scope1, 2 and Scope3): 881,527t-CO2, FY2017 CO2 emissions (the above Scope1, 2 and Scope3): 2,173,996t-CO2, FY2018 CO2 emissions (the above Scope1, 2 and Scope3): 2,149,020t-CO2.）
• 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.

Energy Consumption (GJ)

• Disclosure of energy consumption started from FY2016.
• We revised FY2016, FY2017 and FY2018 figures after reviewing the boundary of the data for more accurate description. （Data prior to revision: FY2016: Consolidated subsidiaries 8,009,967GJ, Total 8,060,660GJ, FY2017: Consolidated subsidiaries 22,496,811GJ, Total 22,545,283GJ, FY2018: Consolidated subsidiaries 23,160,595GJ, Total 23,210,500GJ.）

Electricity Consumption (MWh)

Water Consumption (m³)

• Water consumption has been reduced by installing water-saving device for employee cafeteria and using recycling water for toilet flushing at Head office.
• Components of water source is not subject to assurance engagement.
• We revised FY2018 figures after reviewing the boundary of the data for more accurate description. （Data prior to revision: FY2018: Consolidated subsidiaries 179,921,961m³, Total 179,935,858m³,Third-party sources 3,378,208m³, Ocean 61,700,000m³.）　

Water Discharge (m³)

• Since all sites are discharged into the sewer, it is equivalent to the amount of water consumption.
