Sustainability
Procurement Survey
We conduct an annual sustainability procurement survey of our significant suppliers in order to identify potential sustainability risks in our supply chain and take appropriate measures.
Risk management and KPIs
We use the following steps to identify and manage sustainability risks throughout our supply chain.
- Conduct an annual sustainability procurement survey of significant suppliers and analyze survey results to identify potential sustainability risks in the supply chain.
- For suppliers classified as “high-risk suppliers” as a result of the survey, we conduct interviews to confirm whether or not they plan to make improvements regarding evaluation items (e.g. human rights) that we consider important, and conduct on-site audits as necessary. Second party audits (conducted by purchasing staff) and third-party audits (based on the legal requirements of each country and the requirements of global standard audit standards such as ILO ordinances and RBA) are conducted.
- Send suggestions for improvement to high-risk suppliers regarding items requiring improvement, and work together to improve their efforts.
- Monitor the status of items requiring improvement through annual sustainability procurement surveys.
In conducting the sustainability procurement survey, we set the following KPIs to achieve our goal of “fair and good business relationships with suppliers”, and together we aim to address sustainability-related issues, provide safe and reliable products and services to our customers, and conduct corporate activities that earn the trust of society.

Overview of the survey
Since fiscal 2020, we conduct annual sustainability procurement surveys of significant suppliers.
In FY2024, we introduced EcoVadis*1 , a third-party evaluation platform, and Three companies (NTT, KDDI, SoftBank) Sustainable Procurement Common SAQ*2 (In-house evaluation survey) for sustainable procurement to survey suppliers*3. 67% of our significant suppliers have taken the EcoVadis survey, and we will continue to recommend EcoVadis to our suppliers, aiming to further strengthen risk management and engagement throughout the supply chain by expanding highly transparent and fair sustainability assessment.
Survey Method | All Suppliers | Significant Suppliers |
---|---|---|
EcoVadis | 92 suppliers | 54 suppliers |
Common SAQ | 80 suppliers | 27 suppliers |
Total | 172 suppliers | 81 suppliers*4 |

Results of the survey
The average score rate for the total of the eight items was 77%. The peak values with a high score rate were “1. Respecting the Laws and Internationally Recognized Standards” and “5. Fair Trading and Ethics,” while the peak values with a low score rate were “4. Environments” and “8. Business Continuity Planning.” Results of the analysis of each item are fed back to the surveyed suppliers so that they can compare their own score with the average score of other companies for each item, reconfirm the strengths and weaknesses of their own activities, and use the results as reference in their efforts to continuously improve.

Sections | Maximum point yield | Average scoring rate |
---|---|---|
1. Respecting the Laws and Internationally Recognized Standards | 100 | 87 |
2. Human Rights and Labor | 100 | 84 |
3. Health and Safety | 100 | 82 |
4. Environments | 100 | 61 |
5. Fair Trading and Ethics | 100 | 86 |
6. Quality and Safety | 100 | 73 |
7. Information Security | 100 | 75 |
8. Business Continuity Planning | 100 | 70 |
Total | 100 | 77 |
Identifying sustainability risks
We define “sustainability high risk” as a situation in which suppliers human rights, labor, or environmental practices are inadequate and are likely to have a significant negative impact on our business activities, such as human rights violations that could affect our corporate reputation, poor labor conditions that could reduce the quality of our products and services, or violations of environmental or labor-related laws and regulations.
To identify suppliers having ESG issues or potential risk, we conduct a sustainability procurement survey that evaluates suppliers from eight perspectives, including human rights, labor, and the environment. Suppliers with an average score of 65% or lower and do not meet the criteria to be considered as having a particularly significant risk on the eight criteria are classified as Rank D suppliers, and we work together with them to improve our initiatives.
In FY2024, we identified suppliers that are behind in addressing human rights issues and environmental issues such as setting GHG emission reduction targets as Rank D suppliers and promote corrective measures to address these issues, while striving to raise awareness of the required level of our Supplier Code of Ethical Conduct.
Risk Rank | Evaluation Score | FY2024 | Description |
---|---|---|---|
Rank A | Total 86 or greater with no applicable significant risk items | 35 suppliers (44%) | Suppliers able to act at the level required by our Supplier Code of Ethical Conduct. |
Rank B | Total 66-85 with no applicable significant risk items | 32 suppliers (40%) | There are items where suppliers are not acting at the required level of our Supplier Code of Ethical Conduct, but voluntary improvements are made. |
Rank C | Total 65 or under with no applicable significant risk items | 6 suppliers (8%) | Need to monitor the status of items for which suppliers are not acting at the required level of our Supplier Code of Ethical Conduct based on the improvement plan. |
Rank D (high-risk) |
Total 65 or under with applicable significant risk items | 7 suppliers (9%) | Items that are not performed at the required level of our Supplier Code of Ethical Conduct (some items in human rights, labor, environment) are considered potentially risky and a corrective action plan needs to be created. |
Total | 80 suppliers | Including significant suppliers. |
Supporting improvement activities
For suppliers identified as having sustainability risks as a result of the sustainability procurement survey, which includes items related to human rights, environment, etc., we 1) share the results of the analysis, 2) conduct additional interviews to clarify concerns, and 3) discuss the direction of action to support improvements. In fiscal 2024, seven suppliers were identified as having potential risks to prepare corrective action plans, and we have asked suppliers to take advantage of this assessment to improve their initiatives.
Type of risk | Contents | Number of supported suppliers for improvement in FY2024 |
Improved guidance rate |
---|---|---|---|
Human Rights | No human rights and labor regulations have been established. | 3 companies | 100% |
Environmental Risks | Emission status is not visualized or no specific quantified reduction targets have been set for GHG emissions. | 4 companies | |
Total | 7 companies (including 4 significant suppliers)* | 100% |

Conduct supplier visits
and audits
Since FY2021, we have been inspecting suppliers' compliance with the Supplier Ethics and Rules of Conduct in the areas of human rights, labor, health and safety, and the environment during on-site inspections of suppliers' factories and other facilities by purchasing managers, and have been accumulating records of such inspections. In fiscal year 2022, we have started to conduct third-party audits. The items are based on the legal requirements of each country and the requirements of global standard audit standards such as ILO ordinances and RBA. As a result of the audit, if an ESG issue or potential risk that needs improvement is discovered, an improvement plan will be formulated and implemented after the audit.
On-site audit | FY2023 | FY2024 | FY2025 |

Responsible sourcing of minerals
In order to fulfill our social responsibility in our purchasing activities, we are working with our suppliers to eliminate the use of products containing conflict minerals.
Specifically, our Supplier Ethics and Rules of Conduct stipulates that we do not use tantalum, tin, tungsten, or gold, which are sources of funding for rebel groups that commit human rights abuses in the Democratic Republic of Congo and its neighboring countries, and we require our suppliers to comply with this stipulation.
Survey results
Since 2020, we have conducted a survey of primary suppliers on the country of origin of conflict minerals contained in their products using the Conflict Minerals Reporting Template (CMRT*1) and received responses from 17 companies.
Survey Results | Tantalum (Ta) | Tin (Sn) | Tungsten (W) | Gold (Au) |
---|---|---|---|---|
Total number of refineries for each metal | 39 (Of which, 1 company in target country*2) |
87 (Of which, 1 company in target country*2) |
50 (No target countries) |
156 (No target countries) |
