Responses to climate change

Environmental initiatives

Toward achieving carbon neutrality

The company established a Climate Change Measures Department in December 2021 to grasp the current state of CO₂ emissions throughout the group and to manage action plans aimed at the reduction of CO₂ emissions. Aiming for carbon neutrality by 2050, we built a climate change measures system consisting of top management, and are working on this.

Responses to climate change, a global-scale issue, is now a necessity. As an initiative towards the achievement of carbon neutrality, the company grasped CO₂ emissions in its production activities and set long-term targets for their reduction.

The group as a whole, both in Japan and overseas, will advance reductions step-by-step to achieve “a 30% reduction in CO₂ emissions in fiscal year 2030” and “carbon neutrality in fiscal year 2050,” based on improvements in energy saving, the installation of solar panels, purchasing of renewable electricity, and the trading of CO₂ emissions credits.

The group will fulfill its social responsibilities towards the realization of a sustainable society by implementing various measures.

CO₂ emissions reduction activities

Energy saving and CO₂ emissions reduction initiatives

In Japan, we began the installation of solar panels, the main part of our CO₂ reduction measures, in earnest from fiscal year 2022, and our CO₂ emission reductions have increased. Energy conservation measures are also advancing systematically in parallel, and the reduction results have increased.
Overseas too, like Japan, we are implementing surveys and making plans, and we plan to start energy conservation measures and the installation of solar panels from fiscal year 2023, gradually increasing the reduction results.

However, as production volumes are also increasing, we must accelerate further if emissions are grasped as the absolute volume.
To accelerate investment in CO₂ reductions, the company set internal carbon pricing (ICP) in Japan from fiscal year 2023. We will review ICP once a year in light of the situation in general and at the company. “Fiscal year 2023: 10,000 (yen / t-CO₂)”
In November 2022, we issued a news release announcing that we will make step-by-step investments in energy-saving facilities at bases in Japan to achieve the company’s fiscal year 2030 target for the reduction of CO₂ emissions. A reduction in CO₂ emissions of 10,000 tons is expected based on this initiative.
The company is strengthening the reduction of CO₂ emissions based on these initiatives.

Plan for the reduction of CO₂ emissions(Japan and overseas)

Following on from each of Topre’s divisions and the nine divisions of the group’s domestic companies, each of the group’s overseas companies will start CO₂ reduction plans from fiscal year 2023.

Overview of considerations

[1] First, we will thoroughly implement everyday improvements for energy saving and the successive installation of solar panels on rooftops where they can be installed.

[2] Examples of items for consideration (other than solar panels)

  • - Plant air leakage prevention and supply control
  • - Switch to highly efficient transformers
  • - Change company vehicles to EVs
  • - Change to centralized control of air conditioning
  • - Upgrade to heat exchange type ventilation systems
  • - Adaptation of office buildings, etc. to ZEBs

Switching to LED lights in plants and offices has largely been completed and we are advancing the change from mercury lamps, which consume a lot of electricity, to electricity-saving LED lights. At Tochigi Plant, for example, we reduced electricity consumption by about 70% by switching some lighting from mercury lamps to LED lights.

We are upgrading to highly efficient power transformers and air conditioners. In addition, we are also working on everyday improvements such as reducing power consumption by adjusting the timing of the turning off of power to air compressors and the heating time of heat source equipment for each season.

We are conducting activities aimed at the improvement of fuel efficiency by setting annual fuel efficiency targets. In addition, as an initiative to reduce CO₂ emissions associated with manufacturing, we are actively introducing battery- powered forklifts, which can be expected to reduce CO₂ emissions compared to conventional LPG- powered forklifts. Sagamihara Plant has introduced a total of 35 battery-powered forklifts since 2017.

<Use of renewable energy>
As an initiative for carbon neutrality, we plan to install solar panels in stages on all plant roofs where installation is possible. (We will consider the purchase of renewable energy power in the future.)

Scope 3 Efforts to reduce

Grasping of Scope 3 emissions

Scope 3 emissions are those by other companies aside from CO₂ emissions in production activities. The group’s biggest sources of Scope 3 emissions are in “Category 1 Purchased products and services (54%)” and “Category 11 Use of products sold (38%).”

Scope 3 reduction targets

The group recognizes that the reduction of Scope 3 emissions is an important issue, and set targets for efforts in categories where there are high emissions and the suppression of CO₂ can be expected

We will consider the selection and purchase of lowCO₂ materials and parts to reduce Category 1 emissions. With regard to Category 11 reductions, we will develop a lineup of refrigerated vehicles equipped with electric refrigeration equipment and promote replacement with low-GWP refrigerants. We are promoting subsidies for the purchase of electric vehicles with regard to the reduction of commuting by Category 7 employees.
