The Komori Group pursues environmentally friendly production processes and facilities, promoting CO₂ reduction through improved energy efficiency and the use of renewable energy. In addition, we continue initiatives in energy management, waste reduction, and resource circulation, tailored to the specific characteristics of each site.

At the Tsukuba Plant, a large-scale solar power generation system with a capacity of 1,800 kW was introduced in April 2026 through an on-site PPA scheme, under which Tokyo Gas Engineering Solutions Corporation (TGES), the power generation operator, installs and operates the facilities, and Komori purchases the electricity under a long-term contract. Together with the existing 500 kW facilities, all electricity generated from the total installed capacity of 2,300 kW is consumed within the plant, which is expected to result in an annual reduction of approximately 1,100 t‑CO₂*. In August 2025, Komori Machinery (Nantong), China, introduced a solar power generation system with a capacity of 880 kW through an on-site PPA scheme, which is expected to reduce CO₂ emissions by approximately 530 t per year*. Previously, group company MBO, a postpress equipment manufacturer, installed solar power generation facilities with a total capacity of 734 kW at its plants in Germany in 2022 and Portugal in 2023, equivalent to an annual reduction of approximately 116 t‑CO₂*.

At the Tsukuba Plant, lighting for high factory ceilings, cranes, and offices was converted to LED in 2023, followed by the conversion of outdoor lighting to LED in 2024, equivalent to an annual reduction of CO₂ emissions of approximately 280 t‑CO₂*. At Komori Machinery (Yamagata), LED lighting was introduced in factory and office facilities over the period from 2015 to 2025, equivalent to an annual reduction of CO₂ emissions of approximately 383 t‑CO₂*. Lighting on all floors of the headquarters building was also switched to LED in 2022, and efforts to convert lighting to LED are being promoted at factories and offices across the Group, including group companies.

At the Tsukuba Plant, the heat source equipment for factory air conditioning was upgraded from a conventional gas absorption chiller to an air‑cooled heat pump module chiller, and operation began in January 2026. As a result, annual gas consumption is expected to decrease by approximately 200,000 m³ (about a 45% reduction compared with fiscal year 2024), and total annual CO₂ emissions from electricity and gas combined are expected to be reduced by approximately 383 t‑CO₂*. In addition, one unit of similar equipment at the plant was also upgraded in 2018, equivalent to an annual reduction of approximately 500 t‑CO₂.*

*CO₂ emissions were calculated using emission factors for FY2025 reporting, with electricity emissions based on location‑based emission factors for each country.

In pursuit of environmentally friendly product development, we are continuing our activities to reduce environmental impact and CO₂ emissions throughout the lifecycle of our products, from procurement of raw materials and components to manufacturing and product use.

LITHRONE GX/G advance EX Edition

Escalating energy costs is a major factor suppressing the profit of printing companies. Thus, as a solution offered to support printing companies, Komori introduced in April 2024 an eco-friendly offset printing press designed to reduce greenhouse gas (GHG) emissions.

The company continues to promote proactive information disclosure as part of its environmentally friendly corporate activities as well as activities aimed at increasing corporate value.

Komori supports the Task Force on Climate-related Financial Disclosures (TCFD)recommendation to proactively disclose items related to climate change-related risks and opportunities, and we are tackling the following initiatives:

Komori's basic environmental policy and material issues including climate change countermeasures are reported and discussed in the CSR Committee. The CSR Committee is headed by President and Representative Director and consists of all Directors and Operating Officers, with meetings scheduled to be held four times annually. Its resolutions are presented and reported to the Board of Directors as necessary and reflected in the Group strategies.

The Risk Management Committee has been established as an organization subordinate to the CSR Committee and undertakes initiatives in collaboration with other divisions. In identifying and evaluating risks, those involving all aspects of the business environment including climate-related items are extracted, and the frequency of occurrence and impact of those risks are then evaluated. The progress of the activities are discussed by the Risk Management Committee, with particularly important risks being reported to and discussed by the CSR Committee and the Board of Directors.

To consider the impact of climate change on business, scenario analysis was conducted, taking into account climate-related scenarios released by external organizations such as the International Energy Association (IEA) and the Intergovernmental Panel on Climate Change (IPCC). The analysis makes evaluations based on quantitative and qualitative aspects of impact of climate change as of 2030 as stipulated in Komori Eco Vision 2030.

  ⇒ High: 5% or more, Medium: More than 1% - under 5%, Low: Under 1%
• Impact on which quantitative evaluations are not performed is evaluated based on qualitative study, and qualitative evaluation is indicated with gray coloring.

The company has been promoted activities to reduce CO₂ emissions, such as setting a climate change target of a 50% reduction in total company CO₂ emissions by March 2031 compared to March 2011, with an interim target of a 30% reduction by March 2021, in "Komori Eco Vision 2030" formulated in 2015. From March 2023, the calculation method was changed to use Scope 2 as the market standard in line with the trend towards standardization of greenhouse gas emission calculation methods, and the "Komori Eco Vision" was revised to achieve carbon neutrality by 2050. Scope 1+2 greenhouse gas emissions are targeted to be reduced by 26% by March 2031, with FY2023 as the base year.

Since 2022, Komori has been responding to the CDP* questionnaire.
In CDP 2025, Komori received the following scores:

• Climate Change: B score (Management level)
• Supplier Engagement Assessment (SEA): A score

*CDP (Carbon Disclosure Project) is a global non-profit organization headquartered in the UK that encourages companies, cities, and other organizations to disclose environmental information related to climate change, water security, forests, and other environmental themes, and evaluates their initiatives.
CDP scores are assessed on an eight-level scale (A, A‑, B, B‑, C, C‑, D, D‑) and are widely used by investors, financial institutions, and other stakeholders as one of the key indicators for evaluating corporate sustainability management.
