Environmental Impact

JDI has been working to identify the Scope 3 emissions from its supply chain since fiscal 2021 alongside the environmental load of its own business activities to reduce greenhouse gas emissions over the medium to long term.

Environmental Impact

JDI’s business activities consist of inputting energy and resources for product production, which are accompanied by outputs such as CO2, waste, and so on. An overview of this is shown in the figure below (covering all domestic plants + global manufacturing subsidiaries in FY2021). The basis of JDI’s environmental improvement activities lies in reducing the number of inputs and outputs, and JDI works to address such activities by determining each of these items for every area in a detailed manner.

Environmental Aspects
The priority controlled chemical substances refer to 38 substances selected as being subject to priority control efforts.
The CO2 emissions factor from electrical power in Japan is based on 0.433 t-CO2/MWh (emissions factor released by each power company [factor used to convert greenhouse gas emissions of a specific emitter]). The other conversion factors are from the Act on the Rational Use of Energy and the Act on Promotion of Global Warming Countermeasures. The CO2 emissions factor overseas uses the local emissions factor for Taiwan and the Philippines.
Among substance covered in the Act on Promotion of Global Warming Countermeasures, JDI uses the term “greenhouse gases” to refer to these seven substances: PFC (CF4, c-C4F8), HFC (CHF3, C2HF5), SF6, NF3 and N2O. Emission factors of AR4 are used.
Within Japan, this refers only to emissions of the 38 priority controlled chemical substances designated by JDI, and for overseas it refers only to emissions of VOC.

Greenhouse Gas Emissions based on the GHG Protocol Standard

Environmental Aspects
  GHG Protocol Standard: International standard for calculating and reporting greenhouse gas (GHG) emissions
  Scope1: Direct greenhouse gas (GHG) emissions that are controlled or owned by an organization (fuel combustion/industrial processes)
  Scope2: Indirect greenhouse gas (GHG) emissions associated with the use of electricity, heat and steam supplied by a third party
  Scope3: Indirect emissions other than Scope 1 and 2 emissions (third-party emissions associated with the business activities of an organization)
Reason Some Categories are Not Applicable
  ●Category 8 JDI includes emissions from the operation of tenant offices and other assets leased by the organization as Scope 1 and 2 emissions
  ●Category 13 to 15 JDI does not engage in any applicable operations
