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)

(Unit：t-CO2e)

• We couldn't collect the environmental data for 38 sites due to COVID-19 lockdown or working from home in FY2019. In FY2018, CO2 emissions of these sites were equivalent to about 5.2% of the total CO2 emissions.
• Please refer to the following publication site for CO2 emissions of Sumitomo Corporation head office in Tokyo.
  publication site link (Available in Japanese)
• 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.
• In FY2018 and FY2019, we surveyed non-consolidated and consolidated subsidiaries in Japan, and Scope1 emissions from 6.5 gases were both 0t-CO2e.
  The scope for 6.5 gases is that group companies emit more than 3,000 t-CO2e per year under the Greenhouse Gas Emissions Accounting, Reporting, and Disclosure System in Japan.
• 6.5 gases are not subject to assurance engagement.

CO2 Emissions (Scope3)

(Unit：t-CO2e)

• CO2 emissions (the above Scope1, 2 and Scope3) were 1,760,634t-CO2e/1,641,079t-CO2e/1,537,072t-CO2e in FY2017, FY2018, and FY2019 respectively.
• 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 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 for FY2019 were calculated using the emission intensity for each type of waste, which is published in the emission intensity database (Ver. 3.0) for calculating greenhouse gas emissions and other emissions by organizations throughout the supply chain.
• 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 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."
• 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

(Unit: GJ)

• We couldn't collect the environmental data for 38 sites due to COVID-19 lockdown or working from home in FY2019. In FY2018, energy consumption of these sites were equivalent to about 7.3% of the total energy consumption.
• Energy conversion factor from electricity consumption: 3.6 (MJ/kWh)
• Energy conversion factors from other than electricity consumption are based on the Act on the Rational Use of Energy in Japan.

Electricity Consumption

(Unit: MWh)

• We couldn't collect the environmental data for 38 sites due to COVID-19 lockdown or working from home in FY2019. In FY2018, electricity consumption of these sites were equivalent to about 7.1% of the total electricity consumption.
• The amount of electricity consumption which generated from renewable energy was 112,045MWh in FY2019.

Water Consumption

(Unit: m³)

• We couldn't collect the environmental data for 38 sites due to COVID-19 lockdown or working from home in FY2019. In FY2018, Water consumption of these sites were equivalent to about 50.5% of the total water consumption.
• The above figures in FY2017 and FY2018 were excessive due to incorrect aggregation for several sites.
  Water consumption of those sites in FY2018 were equivalent to about 32.6% of the total water consumption.
• Water consumption has been reduced by installing water-saving device for employee cafeteria and using recycling water for toilet flushing at Head office.

• The above water consumption was calculated based in the water risk level of 3 (High) or higher based on the World Resources Institute (WRI)'s "WRI Aqueduct",
• Components of water source and water consumption in water-stressed areas are not subject to assurance engagement.

Water Discharge

(Unit: m³)

• Since all sites are discharged into the sewer, it is equivalent to the amount of water consumption.
• This item is not subject to assurance engagement.

Waste Emissions

(Unit: t)

• The above figures for Japan include general waste but exclude industrial waste and valuable resource.
• We couldn't collect the environmental data for 38 sites due to COVID-19 lockdown or working from home in FY2019. In FY2018, waste emissions of these sites were equivalent to about 0.6% of the total waste emissions.
• In FY2019, the recycle ratio at the head office, regional offices, branches and sub-branches in Japan was 95.04%, the waste recycling amount was 117t, and the final waste disposal volume was 6t.
• This item is not subject to assurance engagement.

Paper Consumption

(Unit: 1,000 Sheets)

• The above figures are calculated from the purchase cost of office paper and the unit price of A4 size paper.
• This item is not subject to assurance engagement.
