Climate Change Initiatives

In recent years, the environment, in particular climate change, has had a significant impact on the world.
MJC Group considers this fact to be a material matter and, following the Task Force on Climate-related Financial Disclosures (TCFD) framework, the Group makes considerations on the key risks and opportunities related to climate change within the Group and discloses the results of its analysis of its impacts.
In addition, the Group is committed to saving energy and reducing CO₂ emissions to mitigate climate change.


The Group stands by its position that sustainability is an important corporate activity, and therefore has established the following governance structure to achieve medium to long-term improvements in corporate value.

Risk management

At MJC, the president, as our company's chief risk management officer, is in charge of risk management to mitigate and reduce substantial risks to the business, ensuring continuous operation. A Compliance Risk Management Committee has been set up to monitor the activities throughout the Group, ensuring each department’s risk management activities that are assigned every year remain appropriate to any risks that may occur.

The committee reports on their findings to the Management Board as a corporate risk disclosure proposal, on which the Board of Directors deliberates.


The impacts of climate change on business were identified in the Intergovernmental Panel on Climate Change (IPCC), the Sixth Assessment Report, and the International Energy Agency (IEA), under two scenarios: 'Global average temperature increase by 4°C or more' and 'Global average temperature increase well below 2°C as agreed under the Paris Agreement (ideally below 1.5°C)', the risks and opportunities of climate change were identified under these two scenarios.

Transition risks arising under a scenario of well below 2°C were considered for the 2030 time axis, and the physical risks arising under a scenario of 4°C or more were considered for the 2050 time axis.

For opportunities, we considered elements that are important for the Group to achieve its strategy and strengthen its business foundation under both scenarios.

Going forward, while aiming to contribute to society through our business activities, we will further examine the impacts on our business operations and disclose this information in due course.

Category Climate change risks and opportunities identified
Transition Risks Policy / Regulations 1 Increased energy costs due to the introduction of a carbon tax
2 Increased costs due to higher electricity prices
The Market 3 Increases in raw material prices associated with decarbonization
Technology 4 Loss of sales opportunities due to delays in the development of energy-saving technologies
Reputation 5 Decrease in sales due to increasing demands from the stakeholders for more environmentally friendly practices every year and the inability to respond to such demands
Physical Risks Acute Illnesses 6 Shutdowns and recovery costs incurred due to disaster damages to the Company
7 Decrease in sales due to supply chain disruptions, shutdowns or delays in shipments caused by extreme weather events
Opportunities Technology 1 Improved competitiveness via energy-saving product releases
2 Improving the competitiveness of our products by manufacturing products using clean energy
Reputation 3 Increased demand for our products due to the expansion of the semiconductor market, including infrastructure development and digitalisation to curb climate change
4 Improved competitive advantage in dealing with business continuity in the event of a disaster by building BCP measures

Indicators and targets

As part of its contribution to a decarbonised society, the Group plans to reduce its Greenhouse Gas (GHG)*2 emissions in Japan in gradual steps from 2024 onwards. Furthermore, the Group will continue to monitor its GHG emissions under Scope 1*3 and Scope 2*4 and disclose appropriate information.

Changes in the Group's GHG emissions (Scope 1, 2)

GHG emissions(t-CO₂) 2020 Actual 2021 Actual 2022 Actual
Scope1 2,266 2,642 2,814
Scope2 10,505 10,929 11,168
Total 12,771 13,571 13,982
  • *1 Figures are on a consolidated basis, including domestic and international.
  • *2 GHG: Greenhouse Gas
  • *3 Direct emissions: Emissions from the operator's own fuel combustion and industrial processes
  • *4 Indirect emissions: Emissions associated with the use of energy such as electricity, heat and steam supplied by other companies

All domestic establishments are obliged under the Energy Saving Act to monitor their energy consumption and are required to reduce their energy consumption intensity*1 by more than 1% on a five-year average basis for the entire business over a medium to long term.
Over the five-year period from 2018 to 2022, we achieved an average reduction of 9.9% in energy consumption at our domestic sites, far exceeding the minimum target reduction of 1%. Energy consumption has increased in line with increased production and the introduction of new equipment.
MJC will continue to promote reductions in energy consumption intensity and further promote energy saving to mitigate the effects of global warming.

  • *1 Energy consumption intensity: a value representing energy efficiency. The smaller the value, the higher the production efficiency and energy saved, therefore contributing to the mitigation of global warming. (Unit energy consumption for domestic sites is calculated based on energy consumption and production numbers.)
