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.

- 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.).
Introduction of the Internal Carbon Pricing
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.
- Carbon price within Toshiba Group（ICP） : <Japan> 11,931 yen/t-CO2（FY2022） *ICP is country-specific
- Scope : The investment aiming at reducing GHG emissions
- Application method : The amount of GHG emission reductions added as a "deemed benefit" by applying the ICP to the subject capital investment is used as the basis for investment decisions.
Case: Reducing GHG emissions by installing solar panels
Toshiba Transmission & Distribution Systems (India) Private Limited
Today, as a response to the climate change issue, companies are being asked to switch to using electricity from renewable energy sources in their factories. Toshiba Transmission & Distribution Systems (India) Private Limited has been installing solar panels and is proactively introducing electricity from renewable energy sources. The company installed solar panels on its own premises. The company installed their own solar panels on the rooftop of building in Unit-3 and other solar panels under an on-site PPA on the rooftop of building in Unit-10. In addition, the company also have been introducing an off-site PPA. As a result, approximately 14 million kWh per year of renewable energy is generated in total for FY2021, which was used at the site. This figure accounts for approximately 35% of the total electricity used by the site in FY2021, reducing CO2 emissions by approximately 11,320 tons per year. Currently, the company plans to install new solar panels on the rooftop of building in Unit-9. Toshiba Transmission & Distribution Systems (India) Private Limited will continue to proactively introduce renewable energy according to Toshiba Group’s long-term GHG emissions reduction target and contribute to achieving a decarbonized society. (PPA: Power purchase agreement entered into between a power generator, retailer, and a consumer of electricity)
Case: Reduction of Power Consumption by Installing an Inverter in the Scrubber Circulating Pump
Kaga Toshiba Electronics Corporation
Kaga Toshiba Electronics Corporation installed an inverter in the circulating pump used in scrubber equipment. This reduces excessive circulating water and cuts energy used in the pump for that purpose.
Case: Use of Carbon Neutral LNG at Toshiba Group
Toshiba Group is a member of the Carbon Neutral LNG Buyers Alliance and started using Carbon Neutral LNG (CNL) in Fuchu Complex and Komukai Complex for the first time within Toshiba Group. CNL is a type of LNG that offsets greenhouse gases generated in the process from extraction to the burning of natural gas by carbon credits (carbon offsetting) obtained by projects that help conserve biodiversity and reduce poverty in emerging countries. Thus, it is deemed to be carbon neutral on a global scale even when burned. Toshiba Group will contribute to the realization of a sustainable society by responding to climate change and other social issues through increasing the use of CNL.
Management of Ozone-depleting Substances
Toshiba Group treats controlled CFCs, which are ozone-depleting substances, in accordance with the law to reduce GHG emissions.
