In August 2020, we announced our support for the recommendations of the Task Force on Climate-related Financial Disclosures (TCFD) and promoted an analysis of the risks, opportunities, and financial impacts of climate change on our business. We are pleased to disclose some of the results of this study based on the TCFD recommendations.
Based on “Hamamatsu Photonics Group Basic Policy of Sustainability” and “Hamamatsu Photonics Group Environmental Policy,” we recognize that initiatives for climate change is one of the most important issues. The contents of the studies conducted by the Environmental Committee, which are chaired by executive officers, as well as by its subcommittees and working groups under their supervision, are scrutinized by the Sustainability Management Committee, which is chaired by the officer in charge. The Sustainability Management Committee notifies Board of directors of the key issues. The PDCA cycle has implemented to ensure matters pointed out by Board of directors throughout the company.

We recognize that various changes due to climate change will affect our business. In order to identify the most important risks and opportunities, we conducted a scenario analysis at 1.5/2°C and 4°C for our entire business in the following steps.
We identified the climate change risks and opportunities facing the company now and in the foreseeable future. We scrutinized the interests of our stakeholders and their future significance. As a result, we identified 16 transition and physical risks and opportunities.
Degree of Impact | Risks | Opportunities | |
---|---|---|---|
Transition | Physical | ||
High | #1 Increase in operational costs due to introduction of carbon tax/emissions trading scheme #2 Increased burden and risk of fines due to stricter disclosure requirements and regulations #3 Loss of reputation among customers, decrease in sales, and loss of competitiveness #4 Short-term increase in operating costs due to introduction of renewable energy and promotion of energy conservation #5 Tighter regulations on raw materials |
#6 Increased risk of business shutdown and decreased sales due to severe wind and flood damage #7 Increased damage due to severe wind and flood damage #8 Increased air conditioning and cooling costs due to higher average temperatures #9 Increased risk of business shutdowns and decreased sales due to employees' inability to come to work due to higher average temperatures #10 Increased risk of business shutdown and decreased sales due to employees' inability to come to work due to severe wind and flood damage |
#11 Increase in sales through the provision of products and services that contribute to addressing climate change #12 Increase revenues by entering new markets #13 Decrease in expenses due to gains in client and investor reputation #14 Increase in revenues through introduction of renewable energy and promotion of energy conservation |
Mild - Low |
#16 Loss of reputation and competitiveness among investors | ・Decrease in sales resulting from lower production due to lower rainfall at the water sources from which the water is withdrawn |
We set 1.5/2°C and 4°C scenarios for 2030 and considered changes in the external environment and stakeholders with regard to adaptation to climate change and the transition to a low-carbon society. We also projected changes in our customer sectors that may occur as a result of these changes, and examined the degree of impact on our business.
A sensitivity analysis was performed to assess the potential impact of each scenario on our strategic and financial position. For each of the climate change risks and opportunities with a high degree of importance, we examined the business impact calculation methods and calculated and examined them from available internal and external parameters. Examples are as follows;
Types | Impact on Business in 2030 | Potential Financial Impact | ||
---|---|---|---|---|
1.5/2℃ | 4℃ | |||
Risks | Transitional | Decrease in sales due to lower product competitiveness and sluggish customer evaluations | High | - |
Short-term increase in operating costs due to introduction of renewable energy and promotion of energy conservation | Mild | - | ||
Physical | Business shutdowns (production sites, logistics, inventory, supply chain) and sales decline due to severe wind and flood damage | Mild | High | |
Damage to manufacturing sites due to severe wind and flood damage and increased restoration costs | Mild | High | ||
Opportunities | Medical and biotechnology equipment: Increased sales of related products for specimen testing equipment | Mild | Mild | |
Industrial Equipment: Increased sales of related products for EV battery inspection systems | Mild | Mild | ||
Analytical instruments: Increased sales of related products for environmental analysis | Mild | Low |
Based on the results of the project impact assessment, we will consider countermeasures for those items that have a large impact.

We have established environmental management rules and operated a company-wide environmental management system. Environmental risks and opportunities related to climate change are evaluated, and environmental objectives and targets are set for each fiscal year.
The management reviews our performance and challenges, and we strive to improve our environmental performance through continuous improvement.
Risk management for our group, including consolidated subsidiaries, is conducted at the Group ESG Meeting held once a year. The progress of risk management activities at those subsidiaries is reported to the Environmental Committee Secretariat every three months to promote group-wide risk management.
In March 2020, we formulated our Long-term Vision of Global Warming Countermeasures, and are working to cut GHG emissions (scope 1 and 2) from our business activities.
In August 2024, the Long-term Vision has been revised to “Achieving carbon neutral by 2050,” reflecting our new SBT certified target and the applied boundary. Hamamatsu Photonics Group keeps working all together to cut our GHG emissions.
Our greenhouse gas reduction targets (GHG reduction targets) are certified by the SBT Initiative, an international environmental organization as scientifically based and in line with the Paris Agreement.
■HAMAMATSU Group GHG Emission Reduction Targets
Scope 1+2 | ・30 % reduction by FY2031 [Compared to FY2019 (fiscal year ended September 2019)] |
---|---|
Scope 3 | ・Category 11 (Emissions from use of sold products): 15 % reduction by FY2031 [Compared to FY2019] ・Category 1 (Emissions from purchased goods and services): 76 % of suppliers by spend covering purchased products and service will have science-based targets by FY2026. (fiscal year ended September 2026) |
We have joined RE100 (100% Renewable Electricity), an international corporate initiative with the goal of ensuring that 100% of the electricity used in business operations comes from renewable energy sources, on 3rd October 2022. We're committed to sourcing 100% renewable electricity across its entire global operations by 2040.
In the 76th fiscal year (ended September 2023), we have reduced CO2 emissions drastically by 85.7 % comparison with the 72nd fiscal year (ended September 2019) due to introducing renewable energy etc. We keep working to reduce GHG emissions in accordance with our countermeasures.
To grasp the environmental impact of the value chain*, HPK is working on the calculation of Scope 1, 2 and 3 based on the “GHG Protocol.”
* The entire series of processes involving products, including material procurement, production, logistics, use and disposal. Includes both upstream and downstream parts of the Company’s supply chain.

As one of the concrete actions to achieve our carbon neutral, we have introduced CO2-free electricity (about 124 GWh a year purchased from Chubu Electric Power Miraiz Company Inc.) into manufacturing plants and an office in Japan* since October 2022. It contributes to reduction of approximately 55,000 tons-CO2. The overseas plants and offices also are planning to introduce solar-power generating equipment (about 1.1 MW in total) and purchase green power certificates. We keep promoting those actions over the group.

GHG used in semiconductor manufacturing such as HFC, PFC, SF6 and NF3 have large global warming potential (GWP). We are working to reduce its emissions by installing removal equipment and optimizing processes.
Removal equipment
To disclose transparent and reliable information on our GHG emissions data (Scope 1, 2, and 3), we obtained third-party verification by SGS Japan Inc., and their written opinion. We will continue to work to improve the reliability of its data and reduce GHG emissions.
