Response to Climate Change in Business Activities

Toshiba Group is proactively promoting energy-saving measures at its offices as well as business complex and production sites in Japan and abroad. In terms of energy-derived CO₂ emissions from the use of electricity, we are promoting  to turn off electricity at our offices, and in business complex and production sites  as well as making efforts to improve production efficiency as an energy-saving measure and to introduce renewable energy at our business and production sites. In particular, we have been proactively installing systems to capture and/or remove sulfur hexafluoride (SF₆) in particular, which is used to insulate heavy electric machinery, and perfluorocarbons (PFCs), which are used to produce semiconductors. By steadily taking measures to improve our production processes, the Group is contributing to reduce the total volume of GHG* emissions generated from our business activities.

In FY2021, total GHG emissions were 1.03 million t-CO₂, so we achieved our target of 1.10 million t-CO₂. Energy-derived CO₂ emissions per unit activity were 96% compared to the FY2020. Although total GHG emissions have remained almost flat compared to the previous year, per unit activity improved as a result of investment in high-efficiency equipment and other efforts.
Renewable energy accounted for 0.3% of total energy consumption.

Going forward, Toshiba Group will contribute to the realization of a decarbonized society by working to significantly reduce GHG emissions through the promotion of measures such as expansion of the use of renewable energy at our sites worldwide based on our long-term GHG emissions reduction target. As a new initiative under the Seventh Environmental Action Plan, Toshiba Group will also focus on the reduction of GHG emissions through the use of its digital technologies that enable remote operation, automation, and intelligence.

• Carbon dioxide (CO₂), methane (CH₄), dinitrogen oxide (N₂O) (= nitrous oxide), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF₆), and nitrogen trifluoride (NF₃)

• CO₂ emission coefficients for electricity are calculated using emission coefficients provided by power companies.
• Per unit activity refers to values related to energy consumption required for manufacturing (nominal output, the number of products manufactured, number of persons, total floor area, etc.).

In December 2022, Toshiba Group introduced the Internal Carbon Pricing (ICP) system to reduce GHG emissions (Scope 1 and 2) from our business activities. We convert the impact of the investments aiming at reducing GHG emissions on future business into economic value, then by using this information in investment decision making, we will foster internal awareness and promote behavioral change toward carbon neutrality. The ICP will be established on a country-by-country basis based on the future outlook for greenhouse gas emission costs published annually by the International Energy Agency (IEA), and will be reviewed periodically to enhance its operation.
