※About SBTi Certification
SBTi(Science Based Targets initiative) certification is an international system that validates corporate greenhouse gas reduction targets aligned with the Paris Agreement's goal of limiting the global average temperature rise to below 1.5°C compared to pre-industrial levels.

Taking on Decarbonization Management

NAMICS’ corporate philosophy is “Coexistence and Mutual Prosperity for Nature and Humankind,” placing environmental responsibility at the core of our management. Achieving carbon neutrality is both a societal necessity and deeply aligned with this philosophy. As a global company, we comply with international environmental standards and obtained Science Based Targets initiative (SBTi) certification in 2024 based on the international framework.

Under this certification, NAMICS has set targets to reduce Scope 1 and 2 emissions (emissions from our own fuel use and purchased electricity) by 46.2% by 2030 compared to fiscal year 2019 levels and to reduce Scope 3 emissions (across the entire supply chain, including raw material procurement and logistics) by 30% by fiscal year 2032 compared to fiscal year 2022 levels.

By setting these clear numerical targets, NAMICS has established a framework to advance our environmental management quantitatively and continuously. To achieve these goals, NAMICS is promoting the use of renewable energy and the introduction of energy-saving equipment, primarily at our headquarters factory. Initiatives to “create and utilize” energy, such as solar power generation facilities and heat recovery heat pumps, are already underway.

Utilizing Renewable Energy Starting with Factories

Solar Power Generation Equipment (Construction Partner: TESS Engineering)

As a step toward achieving the reduction targets set under the SBT certification, NAMICS installed solar power generation equipment on the roof of the headquarters factory in March 2025. It is expected to generate approximately 120,000 kWh annually, equivalent to the annual electricity consumption of about 30 average households. The anticipated CO₂ reduction effect is approximately 57 tons.

The newly installed solar power generation system primarily utilizes mounting structures with a low center of gravity that do not require foundations. This design is less susceptible to strong winds and reduces the load on the building, enabling safe installation while utilizing the existing structure. By leveraging the advantage of superior construction efficiency without requiring foundation work, we were able to proceed with plans to increase the number of panels.

Power generation and operational status are monitored via a surveillance system. As of 2025, we are measuring power generation to calculate actual CO₂ reduction amounts. By making the generation status “visible,” we aim to foster environmental awareness within the company.

New Equipment Converting Lost “Heat” into Energy

Also in March 2025, we introduced a heat recovery heat pump at our headquarters factory. This system recovers the heat contained in the water used for HVAC system and other purposes, and reuses it for heating, cooling, and hot water supply. At NAMICS, production equipment HVAC system significant amounts of both chilled and hot water, so by recovering the heat from the returning (circulated) chilled water and (circulated) hot water using heat pumps, we can reuse thermal energy that was previously discharged, leading to energy savings.

Through the central monitoring system, we continuously track operational status while recording and managing energy efficiency and anomaly detection. This enables stable heat supply while maintaining efficient operation. The equipped chillers are specified as salt-resistant, making them suitable for locations near the Sea of Japan that are susceptible to sea breeze effects.

The introduction of this heat pump chiller is expected to reduce energy consumption at NAMICS by approximately 1,200 MWh annually. Estimates indicate this equipment alone could achieve about 20% of the reduction target set for 2030. Plans are underway to calculate the actual annual reduction effect by collecting and analyzing various equipment and fluid parameter data after operation commences.

Realizing a Decarbonized Society and a Sustainable Future

NAMICS is advancing to the next stage in realizing a decarbonized society. Aside from our headquarters factory, we are expanding renewable energy facilities to other sites and are utilizing off-site PPAs (Power Purchase Agreements) beginning in November 2025. Regarding renewable energy, we are investigating and considering options beyond just solar power generation with a wide perspective, aiming to achieve carbon neutrality by 2050.

Internally, environmental initiatives are expanding following the acquisition of Science Based Targets initiative (SBTi) certification. Moving forward, we will utilize training programs and our internal portal to foster a culture where every employee takes ownership of environmental challenges as their own responsibility.

On the other hand, in achieving carbon neutrality we also face challenges, which include capital investment, operational costs, technical difficulties, and raw material procurement. Addressing these challenges requires collaboration not only within our company but across the entire supply chain. While utilizing external support systems, we will explore feasible methods with our partners, aiming to solve challenges across the entire supply chain, including utilizing raw materials with lower environmental impact and procuring recycled materials.

NAMICS will continue to advance the creation of a sustainable future under the guiding principle of “Coexistence and Mutual Prosperity for Nature and Humankind,” working alongside stakeholders such as local communities and business partners, and strive for harmony between the environment, society, and the economy.
