Responses to climate change
Environmental initiatives
Toward achieving carbon neutrality
The Topre Group 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, are now a necessity. As an initiative towards the achievement of carbon neutrality, the Topre Group has grasped CO₂ emissions in its production activities and set long-term targets for their reduction. The Topre Group as a whole, both in Japan and overseas, will advance reductions step-by-step to achieve “a 46% 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.
*In July 2025, the target for the reduction of CO₂ emissions by fiscal year 2030 was changed from a “reduction of 30%” to a “reduction of 46%.”
In addition, the Topre Group has confirmed that our climate change policies are aligned with those of the Japan Auto-Body Industries Association Inc. (JABIA), of which we are a member, and we have clear policies for responding appropriately in the event that any differences arise, as necessary. Specifically, original targets have been set by JABIA, based on the Paris Agreement, and subcommittees have been launched, while seminars are also frequently held for member companies. We examine whether these activities are aligned with the Topre Group’s climate change policies, and whether they deviate significantly from our approach and direction, and we will consider a response in the event of significant deviation.
At each of our bases in Japan and overseas, the Topre Group supports laws and regulations related to climate change, the reduction of energy consumption, etc. (in Japan, this includes the “Act on Promotion of Global Warming Countermeasures (Global Warming Act)” and the “Act on Rationalization of Energy Use and Shift to Non-fossil Energy (Energy Efficiency Act),” as well as related measures, etc. By responding appropriately to these laws, regulations, measures, etc., we will fulfill our social responsibility as we work to realize a sustainable society.
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. We started energy saving measures and the installation of solar panels from fiscal year 2023, and the reduction results are increasing gradually.
ICP settings
Because production volumes have risen in association with the expansion of sales in recent years, we must accelerate CO₂ emissions reductions further if the CO₂ emissions reduction target is taken as an absolute amount.
To accelerate investment in CO₂ reductions, the group 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 2024: 10,000 (yen / t-CO₂ )”
To achieve its CO₂ emissions reduction target for fiscal year 2030, the group is strengthening CO₂ emissions reductions by investing in energy-saving equipment in stages at domestic bases based on the news release issued in November 2022.
Overview of the plan for the reduction of CO₂ emissions
We are considering the introduction of energy-saving equipment and solar panels, and measures for lower carbon energy at bases in Japan and overseas, and accumulating results in CO₂ emissions reductions.
Plan for the reduction of CO₂ emissions (Japan and overseas)
Overview of considerations
1. 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 LED lighting
- Visualization of energy
- Upgrade 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
＜Lighting＞
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.
＜Equipment＞
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.
＜Logistics＞
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 39 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.
Actual status of carbon neutral plants
Initiatives at the Saitama Plant
In fiscal year 2024, we achieved carbon neutrality at our Saitama Plant through offsetting by purchasing J-Credits for Scope 1, and switching to power generated from renewable energy for purchased electric power for Scope 2.
Initiatives at Gifu Plant
In fiscal year 2024, we achieved carbon neutrality at our Gifu Plant, through offsetting by purchasing J-Credits for Scope 1, and using renewable energy generated from local biomass power plants for Scope 2, thereby also contributing to the local community through the “local production and local consumption of electric power.”

Scope 3 Reduction Initiatives
Grasping of Scope 3 emissions
Scope 3 emissions are those by other companies aside from CO₂ emissions in production activities. The Topre Group’s biggest sources of Scope 3 emissions are in “Category 1 Purchased products and services (57%)” and “Category 11 Use of products sold (36%).”
Scope 3 reduction targets
The group recognizes that the reduction of Scope 3 emissions is also an important issue, and has 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 low-CO₂ 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.

Response to CDP
CDP (formerly the Carbon Disclosure Project) is an international nonprofit organization that requests environmental disclosure from companies, cities, regions, and governments regarding climate change, water resources, and forest resources.
It provides a framework for businesses and municipalities to disclose their environmental impact and advance their sustainability efforts.
Topre has been responding to CDP questionnaires since 2017 and currently discloses its responses and evaluation results.
