GHG Emissions Throughout the Value Chain
Calculating GHG Emissions Throughout the Value Chain (Fiscal 2023)
Hitachi calculates greenhouse gas (GHG) emissions throughout the Value chain by referencing GHG Protocol standards. This gives us a good grasp of emission hotspots in our value chain with which we can establish effective targets and reduction measures. Most of the greenhouse gases emitted by Hitachi as a whole are energy-related CO2.
An extremely high share of our value chain emissions comes from the use of the products and services we sell. We thus believe that we can make a major contribution to decarbonization through our businesses by giving priority to enhancing the efficiency and energy-saving features of our products and services.
In-house:Within the scope of the company’s organizational boundaries. In principle, all business activities of the company itself and activities within or controlled by its consolidated subsidiaries.
Upstream:In principle, activities related to products and services that are purchased.
Downstream:In principle, activities related to products and services that are sold.
