Calculation of GHG Emissions Throughout the Value Chain

We calculate greenhouse gas (GHG) emissions throughout the entire value chain to more effectively reduce these emissions. As a substantial amount of emissions comes from use of the products we sell, we make an ongoing effort to reduce emissions by enhancing the efficiency and energy-saving features of our products and services during their use.

Categories of GHG Emissions in the Value Chain

Image

  • In-house: Within the scope of the company's organizational boundaries. In principle, the scope of all business activities of the company itself and activities within or controlled by its consolidated subsidiaries.
  • Upstream: In principle, activities related to purchased products and services.
  • Downstream: In principle, activities related to sold products and services.

Note
Figures in parentheses are percentages of GHGs emitted throughout the value chain.
*1
Includes SF6, PFC, HFC, N2O, NF3, and CH4. The gas and fuel conversion factor is based on the list of emissions and calculation methods published by Japan's Ministry of the Environment.
*2
The CO2 electrical power conversion factor used to calculate emissions uses the 2005 emission coefficients for individual countries published by the International Energy Agency (IEA) in the 2010 edition of CO2 Emissions from Fuel Combustion.
*3
Cannot be determined due to insufficient information on processing.
*4
CO2 emissions per unit is based on the Inventory Database for Environmental Analysis (IDEA), developed by the National Institute of Advanced Industrial Science and Technology (AIST) and the Japan Environmental Management Association for Industry (JEMAI).
