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 GHG emissions throughout the group and to manage action plans aimed at the reduction of GHG 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 GHG 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 GHG 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 GHG 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.
GHG emissions reduction activities
Energy saving and GHG emissions reduction initiatives
In Japan, we began the installation of solar panels, the main part of our GHG emissions reduction
measures, in earnest from fiscal year 2022, and our GHG 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 GHG emissions reductions further if the GHG emissions reduction target is taken as
an absolute amount.
To accelerate investment in GHG emissions reductions, the Topre Group set internal carbon pricing
(ICP) in Japan from fiscal year 2023.
Wewill review ICP once a year in light of the situation in general and at Topre.
“Fiscal year 2025: 10,000 (yen / t-CO₂eq)”
To achieve its GHG emissions reduction target for fiscal year 2030, the Topre Group is strengthening
GHG 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 GHG 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 GHG emissions
reductions.
Plan for the reduction of GHG 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
From fiscal year 2024, we have 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
From fiscal year 2024, we have 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.”
State of installation of solar panels
The Topre Group is advancing the installation of solar panels at each base in Japan and overseas as an effort towards the achievement of carbon neutrality by fiscal year 2050 The reductions listed for each base are the estimated annual CO 2 emissions reductions calculated by using the estimated annual power generation of the solar panels to find the reduction in purchased electricity and convert that reduction effect to CO 2 emissions.

Scope 3 Reduction Initiatives
Grasping of Scope 3 emissions
Scope 3 emissions are those by other companies aside from GHG emissions in production
activities.
The Topre Group’s biggest sources of Scope 3 emissions are in “Category 1 Purchased products
and services (48%)” and “Category 11 Use of products sold (43%).”
Scope 3 reduction targets
The Topre 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 GHG emissions and the suppression of GHG emissions 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
The CDP (formerly the Carbon Disclosure Project) is an international non-profit organization
that calls on companies, municipalities, and regional and national governments to disclose
environmental information related to climate change, water resources, and forest
resources.
It provides a framework for companies and public bodies to disclose their impact on the
environment and promote sustainable initiatives. Topre has been responding to the CDP
questionnaire since 2017, and we are currently publishing the answers and evaluation
results.
