Responding to Climate Change

In September 2022, the Company's Board of Directors approved a resolution to endorse the TCFD recommendations.
Based on the recognition that addressing climate change is one of the most important management issues, we will promote initiatives and information disclosure to reduce greenhouse gas emissions, including identifying and addressing climate change-related risks and opportunities.


We established the Sustainability Committee (chaired by the President). The purpose of this body, which is supervised by the Board of Directors, is to promote activities related to sustainability including activities to address climate change and determine sustainability strategies. We also established the Sustainability Promotion Committee (chaired by the director in charge of sustainability) as a subordinate body of the Sustainability Committee to promote various sustainability-related activities.
The Sustainability Committee reports to the Board of Directors on its deliberations and on any climate change-related risks and opportunities it identifies. In addition, the Sustainability Committee reflects these in the Medium-Term Management Plan and business plans. By integrating sustainability-related activities and business strategies, it will work to sustainably enhance our corporate value.
The Sustainability Committee, under the supervision of the Board of Directors, is in charge of promoting various activities related to climate change.


We have conducted a scenario analysis of the impact of climate change risks and opportunities on our company.
In this scenario analysis, the project used external experts to identify and assess the significance of climate change-related risks and opportunities to define scenarios, quantitatively assess business and financial impacts, and consider measures to address the risks and opportunities.
The scenario analysis requires selecting and setting up several temperature range scenarios. We thereafter considered the impact on the Group by drawing up models for the following two scenarios based on scientific information such as that of the IPCC (Intergovernmental Panel on Climate Change) and that of the IEA (International Energy Agency).
We have confirmed that under any of the scenarios in this analysis it is possible to conduct resilient management.
In the 1.5°C scenario, it is assumed that regulations for decarbonization will be strengthened. The introduction of a carbon tax, combined with soaring raw material prices, will drive demand for the creation of more decarbonized products and services. On the other hand, in the 4°C scenario, the impact of physical risks will increase, giving rise to the need to respond to risks such as factory shutdowns and supply chain disruptions, as well as demand for infrastructure reinforcements.

Item 1.5°C scenario where climate change countermeasures, regulations, etc., are advanced 4°C scenario where climate change countermeasures, regulations, etc., are not advanced
Overview of scenarios Scenarios in which severe measures are taken against climate change and the temperature rise is suppressed to about 1.5°C or less by 2100 compared to before the industrial revolution Scenarios in which effective measures against climate change are not in place and temperatures rise by about 4°C by 2100 compared to before the industrial revolution
Model Scenarios of increased transition risks in policy and regulation, markets, technology, and reputation Scenarios of increased physical risks, such as more severe natural disasters, rising sea levels, and more extreme weather events
Regulations on climate change are strengthened, such as the introduction of a carbon tax. Consumer preferences shift to an environmental focus. Climate change causes more extreme weather events and more natural disasters.
Parameters used when estimating impact The RCP 2.6 scenario was used, by referring to information from the IPCC and the IEA. The RCP 8.5 scenario was used, by referring to information from the IPCC and the IEA.
Overview of results Mainly transition risks/opportunities are manifested. Mainly physical risks/opportunities are manifested.
Climate change regulations and changes in consumer preferences will require increased costs and the development of environment-friendly products.
There is a risk of factory shutdowns and supply chain disruptions due to an increase in natural disasters.
Growth in the ZEH (net zero energy house) and ZEB (net zero energy building) market and the use of wooden buildings, which have a decarbonization effect, could increase demand for decarbonization products.
The need to reinforce infrastructure, including buildings, is becoming apparent.
Countermeasures Capital investment and R&D investment have been focused on energy conservation. Going forward, in light of stricter regulations for decarbonization and growing environmental awareness, we will not only promote energy conservation but also R&D investments including the review of product materials Until now, we have prepared for natural disasters, etc., using a BCMS (Business Continuity Management System). We will continue our BCMS activities and strengthen our risk response measures to natural disasters.

Points common to both scenarios

The Sustainability Committee is the central component of our system for promoting activities related to sustainability, including climate change issues. Under this system, we will refine our assessment of risks and opportunities and further develop our response measures.

Category Event Major potential financial impact Financial impact Time frame of occurrence
Transition risks Policies and regulations Introduction of carbon tax The introduction of a carbon tax increases the cost of CO2 emissions. Medium Medium term
Enforcement of energy conservation standards Sales slow down due to higher transition costs and failure to meet standards as a result of the reinforcement of the Act on Rationalizing Energy Use and stricter CO2 emission reduction targets. Major Short term to medium term
Shift to renewable energy Costs increase due to higher prices for renewable energy. Medium Medium term
Stricter regulations on waste disposal Waste disposal costs increase and a shift to reusable or recyclable products is required. Minor Medium term to long term
Technological risks Need for environment-friendly products Costs increase due to switching to components that address climate change, and sales opportunities are lost due to delays in responding to climate change. Major Short term to medium term
Transition to low-emission technologies Product competitiveness weakens on higher costs associated with the transition to low-carbon materials. Minor Short term to medium term
Market risks Shrinking product demand Growing environmental awareness stifles demand for products with high CO2 emissions. Major Medium term to long term
Market uncertainty Unexpected fluctuations in energy costs arise. Minor Medium term
High raw material costs Profit declines due to an inability to pass on rising raw material costs to sales prices. Major Medium term
Reputation Changes in consumer preferences Sales opportunities are lost due to a slow environmental response. Major Medium term to long term
Consumable materials avoided by consumers Sales of consumables that cause CO2 emissions decline as consumers avoid them due to their image as disposable items. Medium Medium term to long term
Corporate reputation A slow environmental response impacts our corporate image, hampering hiring efforts and causing a decline in the share price. Non- calculated Short term to medium term
Physical risks Acute Chronic Increase in natural disasters Flooding caused by extreme weather leads to factory shutdowns and supply chain disruptions. Major Short term to medium term

Resilience is also enhanced by continuously strengthening the BCP of the entire supply chain in preparation for disasters. Medium Short term to long term
Time horizons
In assessing the risks and opportunities associated with climate change, we have established the following time horizons:
  • short term: up to about two years
  • medium term: about three to 10 years
  • long term: 10 years or more

Risk management

As a result of the materiality identification conducted as one of the various sustainability-related activities, we have positioned addressing climate change as an extremely important issue both from our stakeholders perspective and from our own perspective.
Activities related to climate change are led by the Sustainability Promotion Committee, a subordinate body of the Sustainability Committee, which promotes the identification, assessment, and management of risks, which are then discussed and decided by the Sustainability Committee.
In the scenario analysis, risk management will be ensured with periodic assessments of the business or financial impact of each risk quantitatively, including new regulatory assessments.
The results of the climate change risk assessment are reported to the Board of Directors and reflected in thinking for the Medium-Term Management Plan and business plans. These risks are integrated with Companywide risk management in coordination with the Corporate Governance Committee (which is attended by all directors, including outside directors, and held four times a year), a body whose purpose includes promoting corporate ethics, legal compliance, and risk management.

Goals and results

In fiscal 2022, CO2 emissions were 1,770 tons for Scope 1 (direct emissions from business), 13,658 tons for Scope 2 (indirect emissions from power consumption), and 2,848,031 tons for Scope 3 (indirect emissions other than Scopes 1 and 2 [emissions by other companies related to business activities]). Of Scope 3, Category 11 emissions (emissions from the use of products sold) were 2,515,136 tons. In light of our high CO2 emissions in Scope 3 Category 11, we have set the following medium- to long-term goals for minimizing climate change-related risks with CO2 emissions as the indicator.

Item Medium- to long-term goals Fiscal 2022 actual
Scopes 1 and 2 carbon neutral 1.Reduce CO2 emissions 50% from fiscal 2018 level by 2030
