Business Activities and Environmental Impact

The SII Group believes that understanding environmental impact properly throughout the product life cycle is the basic practice of environmental activities. The overview of FY 2020 environmental impact is explained below.

Business Activities and Environmental Impact

*1: Transportation among the SII Group companies in Japan

*2: Estimated annual energy consumption of Green Products certified up to FY 2020.

INPUT
Packaging : Plastics and paper to be recycled according to the Law for Promotion of Sorted
Office Paper : Paper for printers and copiers
Chemical
Substances
: PRTR hazardous chemical substances, HFCs, PFCs, SF6, NF3 and VOC
Electricity : Power purchased from electric companies
Gas : City gas and LP gas
Fuel : Kerosene and heavy oil
Water : Tap water, industrial water and groundwater
OUTPUT
CO2 : From use of electricity, gas, oil, and cooling and heating water
NOx : From use of gas and oil
SOx : From use of oil

*NOx and SOx figures represent business units installing soot and smoke emitting facilities which are regulated by the Air Pollution Control Law.

Chemical
Substances
: PRTR hazardous chemical substances, HFCs, PFCs, SF6, NF3 and VOC discharged into the atmosphere and water
Waste Water : Released into rivers and sewer systems
COD
(Chemical Oxygen Demand)
: Pollution load

*Limited to the business units subject to the regulations in the Water Pollution Control Law covering the total pollution amount

BOD
(Biochemical Oxygen Demand)
: Pollution load

*Limited to the business units installing specified facilities as prescribed by the Water Pollution Control Law

General Waste : Paper and food wastes generated by or as a result of industrial operations
Industrial Waste : Waste oil, acid, alkali, plastics, ash, sludge, and other materials generated by or as a result of industrial operations
Final Landfill Rate : The ratio of the landfill amount to the total waste amount

Results of Water-Quality and Atmosphere Measurements

Environmental Accounting

In FY 1999, the SII Group introduced an environmental accounting system which comprehends and assesses the cost and effect of environmental activities in a quantitative way. To operate the system, we established the SII Environmental Accounting Guidelines based on the guidelines of the Ministry of the Environment.
The FY 2019 results show that the total investment was 376 million yen, which was 40 million yen more than the total for FY 2018, and the total expenses were 1,449 million yen, which was 265 million yen less than the total for FY 2018.

Environmental Protection Costs

Scope: SII sites in Japan
Period: from April 1, 2020 through March 31, 2021

*1 The investment for FY 2019 only. In case we judged that the total outlay included any costs other than environmental protection costs, only the proportion deemed to apply to environmental protection was counted.

*2 Includes depreciation expense for FY 2018 or before. (Equipment and facility investment are depreciated over 5 and 10 years, respectively, in equal yearly increments.) In case we judged that the total outlay included any costs other than environmental protection costs, only the proportion deemed to apply to environmental protection was counted.
