Eco factories

In pursuit of environmentally friendly production and facilities, the company continues to focus on reducing energy use, energy management, waste reduction, and circulation of resources.

Adoption of solar power generation equipment

At the Tsukuba Plant, a large-scale 500kW solar power generator was installed on the rooftop, and the electricity generated in the fiscal year ended March 31, 2023 at 597,000kWh was fully used in the plant, equivalent to a reduction of 259.2 t-CO2*.
Group company MBO, a manufacturer of post presses for the post-printing process, added on facilities to their plant in Germany in 2022 for output of 117kW, and installed facilities in the Portugal Plant in 2023 for output of 590kW, and is consuming electricity in-house and selling the electricity as well.

LED lighting installed

At the Tsukuba Plant, ceiling lighting, crane lighting, office and plant fluorescent lighting have all been changed to LED in the fiscal year ended March 31, 2023, and CO2 emissions are expected to be reduced by 245.2t-CO2* in the fiscal year ending March 31, 2024.
Lighting on all floors of the headquarters building was switched to LED in the same fiscal year, and group companies are also working to change lighting to LED.

Upgrade of heat source equipment for energy-efficient air conditioners

In December 2018, the plant upgraded the air-cooled heat pump chiller used for some of its air conditioning system to the model certified by the Ministry of the Environment as the most energy efficient. Compared to before, the Tsukuba Plant's total gas consumption decreased by approximately 35% and water consumption during summer also decreased by about a third. CO2 emissions decrease by approximately 500 tons as a result.

Eco products

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.

Development of eco-friendly products

LITHRONE GX/G advance Series

With the recent rapid changes in the social and economic environment, there is a growing need for management transformation through more efficient and labor-saving printing machinery, consequently ROI (return on investment) is given special emphasis. The LITHRONE GX/G advance Series has gone through constant technological evolution. In addition to superior specifications such as high-speed printing and various printing formats, the series has realized productivity improvements including reduced start-up and preparation time, automated presetting, and significantly reduced make-ready time, which greatly contributes to ROI. Since its development, the series has reduced CO2 emissions over its entire lifecycle, contributing to the sustainability of not only customers but also society.

Eco communication

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.

Disclosure based on TCFD recommendations

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.

Risk management

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.

Evaluation Indicators

  • Quantitative evaluations have been performed with the following criteria on items that (potentially) impacted operating income performance in the fiscal year ended March 31, 2022:
    ⇒ 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.

Indicators and targets

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.
