Environmental Performance

Environmental Performance

Sumitomo Chemical collects and totals environmental data for the Company and Group companies in Japan, including data on energy and resource consumption, production quantities, and environmental impact (e.g., release of pollutants into the air and water).

Primary Environmental Performance (Fiscal 2018)

  1.  The energy (calculated as kl of crude oil) and greenhouse gas (all seven gases) indices were calculated in accordance with the GHG Protocol (refer to “Calculation Standards for Environmental and Social Data Indicators”) for principal consolidated Group companies in Japan, which account for up to 99.8% of consolidated net sales.
    • Having adopted the GHG Protocol standards for our GHG emission disclosures, we now include the following data that was not included in previous calculations: amount of energy used to produce electricity and steam sold to external parties by the Group and the resultant CO2 emissions; amount of energy used by Sumitomo Chemical and Group companies in Japan non-production sites and the resultant CO2 emissions; CO2 emissions from non-energy sources not included in the scope of the Act on Promotion of Global Warming Countermeasures. 
  2. Calculations include the following 12 metals: iron, gold, silver, copper, zinc, aluminum, lead, platinum, titanium, palladium, gallium, and lithium. 
  3. Calculations include the following seven rare metals: nickel, chromium, tungsten, cobalt, molybdenum, manganese, and vanadium. The supply structure for each of these rare metals is extremely fragile. These rare metals are subject to national stockpiling. 
  4. Fluorescent lamps and mercury lamp ballast as well as contaminated substances (wastepaper, etc.), including PCB waste, are not included in unit and volume data. 
  5. Certain assumptions were made in calculations due to the difficulty of obtaining weight-based figures for some products. 
  6. Calculated based on the amount released into water/the air of each substance subject to the Order for Enforcement of the PRTR Act.

    In fiscal 2018, we revised the method for calculating the emissions of specified substances into water. Using the previous calculation method, emissions totaled 43 tons for both Sumitomo Chemical and Group companies in Japan and 38 tons for Sumitomo Chemical alone.

  7. The amount of coal ash generated at Sumitomo Joint Electric Power, which is included in “Waste emissions” and “Landfill” (Sumitomo Chemical and Group companies in Japan) is calculated on a dry-weight basis.
    In addition, although the amount of waste generated at Group companies in Japan and reduced at Sumitomo Chemical’s facilities is included in “Waste emissions” (Sumitomo Chemical and Group companies in Japan), the amount is insignificant.
  8.  In reference to the Act on Promotion of Global Warming Countermeasures, companies that emit less than 3,000 tons of CO2-equivalent per year for each type of green-house gas are outside the boundary of calculation. 

Environmental Performance (Fiscal 2016–2018), Boundary: Sumitomo Chemical and Group Companies in Japan

Note: The number of companies included in the boundary of calculation for the environmental performance data is as follows for each year.
FY2016: Sumitomo Chemical and Group companies in Japan: 19 companies
FY2017: Sumitomo Chemical and Group companies in Japan: 21 companies
FY2018: Sumitomo Chemical and Group companies in Japan: 21 companies

  1. From fiscal 2017, the energy (calculated as kl of crude oil) indices were calculated in accordance with the GHG Protocol (refer to “Calculation Standards for Environmental and Social Data Indicators”).
    • Having adopted the GHG Protocol standards for our GHG emission disclosures, we now include the following data previously excluded from calculations: amount of energy used to produce power and steam sold to external parties by Sumitomo Chemical and Group companies in Japan (the portion attributable to energy provider subsidiaries was included in years prior to fiscal 2016). In addition, the amount of energy used by Sumitomo Chemical’s non-production sites is included from fiscal 2017, and the amount of energy used by the Group companies in Japan non-production sites is included from fiscal 2018. From fiscal 2018, the boundary of calculation has been expanded to include principal consolidated Group companies in Japan, which account for up to 99.8% of consolidated net sales.
  2. Calculations include the following 12 metals: iron, gold, silver, copper, zinc, aluminum, lead, platinum, titanium, palladium, gallium, and lithium.
  3. Calculations include the following seven minor metals: nickel, chromium, tungsten, cobalt, molybdenum, manganese, and vanadium. The supply structure for each of these minor metals is extremely fragile. These minor metals are subject to national stockpiling.
  4. Fluorescent lamps and mercury lamp ballast as well as contaminated substances (wastepaper, etc.), including PCB waste, are not included in unit and volume data.
  1. Certain assumptions were made in calculations due to the difficulty of obtaining weight-based figures for some products.
  2. Calculated based on the amount released into water/the air of each substance subject to the PRTR Act. From fiscal 2018, we revised the calculation method for specified substances released into water. Using the previous method, water pollutant emissions for Sumitomo Chemical and Group companies in Japan would be 43 tons.
  3. From fiscal 2018, as a result of revising the calculation method for specified substances released into water, water pollutant emissions decreased compared with the previous method.
  4. The amount of coal ash generated at Sumitomo Joint Electric Power, which is included in “Waste emissions” and “Landfill” (Sumitomo Chemical and Group companies in Japan) is calculated on a dry-weight basis. Moreover, although the amount of waste emissions from Sumitomo Chemical and Group companies in Japan includes the amount of waste reduced at Sumitomo Chemical’s facilities, the reduced amount is insignificant.
  1. From fiscal 2017, the greenhouse gas (all seven gases) indices were calculated using the GHG Protocol for greenhouse gas emissions (refer to page “Calculation Standards for Environmental and Social Data Indicators”) for principal consolidated Group companies in Japan, which account for up to 99.8% of consolidated net sales.
    • Having adopted the GHG Protocol standards for our GHG emission disclosures, we now include the following data that was previously excluded from calculations: CO2 emissions from energy sold to external parties by Sumitomo Chemical and Group companies in Japan (the portion attributable to energy provider subsidiaries was included in years prior to fiscal 2016); CO2 emissions from energy use attributable to Sumitomo Chemical’s non-production sites; and CO2 emissions from non-energy sources not included in the scope of the Act on Promotion of Global Warming Countermeasures. In addition, from fiscal 2018, we include energy use attributable to the Group companies in Japan non-production sites.
  2. Outside the scope of reporting under the Act on Promotion of Global Warming Countermeasures.
  3. Calculated based on the amount released into water/the air of each substance subject to the PRTR Act.
