Reduction of Energy Use

Our initiatives

CO₂ emissions (Scope 1 & 2) from energy consumption in FY2024 were 7,128 t-CO₂e, achieving a 28.7% reduction in comparison with FY2022. Emission intensity in FY2024 was 84 (with emission intensity in FY2022 set as 100), indicating steady improvement. This was achieved through creative measures and improvement activities we have continuously devised and implemented to streamline production and save energy. As was done last year, we worked to ensure the use of renewable energy at our head office locations, which are not production sites, by purchasing non-fossil-fuel certificates for electric power consumption in FY2024. We do not use global warming-causing chlorofluorocarbons as a raw material or in our manufacturing processes.

▼CO₂Emissions (Scope 1& 2)

We have also calculated Scope 3 emissions in order to consider and implement the reduction of CO₂ emissions in the supply chain. Since the proportion of Category 1 emissions (purchased goods and services) (approx. 72％) and Category 12 emissions (end-of-life treatment of sold products) (approx. 23％) is high, we will proceed with considerations for further reductions primarily in Category 1.

Domestic and Overseas Initiatives

CO₂ emissions from energy consumption in FY2024 were 39,380 t-CO₂, constituting a 9.6％ reduction in comparison with FY2022. Going forward, in order to achieve our target, we will increase use of renewable energy and reduce CO₂ emissions throughout the Group, by increasing the numbers of solar panels and introducing new solar generation equipment at plants both in Japan and overseas.

Use of Renewable Energy

Solar Power Generation (for Internal Use)

Combining the No.1 power plant on the west side of the site and the No.2 power plant on the roof of the warehouse building, the solar power plants at our Shiga Plant generate around 2 million kWh of electricity per year (equivalent to the electric power consumption of approximately 550 households), and use the FIT (Feed-in Tariff) system for renewable energy. As of the end of 2023, we have also installed a 63 kWh solar power generation system in the administration building, to reduce electricity consumption through power generation for internal use. We are also participating in Maibara City's ECO VILLAGE Concept, and are planning to lease land and use solar power generated on it. Our Tokyo Plant uses 30 kWh of power from solar power, and our Osaka Plant will install new solar panels in 2024, with a capacity of 40 kWh. Overseas, the introduction of solar panels is progressing at our Bhiwadi (due to start operation in 2023) and Panori (2024) sites in India, and at Homewood in the United States (2024), with the whole Group working to reduce CO₂ emissions.

Purchasing Electricity from Renewable Sources

From 2024, we plan to switch electric power used at all of our plants to renewable energy-derived power options.
