Specific actions taken regarding materiality

Measures in material procurement

We have a system for explaining the Daigas Group Procurement Policy and the Daigas Group Procurement Policy for Suppliers to our suppliers and confirming their commitment to sustainable activities before proceeding with a new business transaction. In FY2021, a questionnaire survey was conducted of 177 major suppliers to check their sustainability efforts. Furthermore, when the suppliers conduct business transactions with the Daigas Group, they are asked to observe the “Green Purchasing Guidelines” set by the Group, which are attached to the specifications for the transactions.

Revision to the “Green Partner Initiative”

The “Green Partner Initiative” adopted by Osaka Gas is designed to promote environmental conservation by suppliers of gas pipeline materials. Under the system, suppliers that are recognized as being active in environmental conservation activities such as the building of an Environmental Management System (EMS) will be registered as Partners. Osaka Gas initially focused on suppliers of gas pipelines for its “Green Partner Initiative.” In FY2016, the Company revised the initiative to cover companies other than suppliers of gas pipeline materials as well. As of the end of FY2021, 110 suppliers were registered as Partners.

Sustainability activity survey of suppliers conducted to promote information sharing on social and environmental issues to be tackled by companies

We conduct a questionnaire survey of suppliers on sustainable activities to provide a sense of security to customers when they choose the Daigas Group, as well as taking into account social and environment aspects in doing business. The survey is based on the Daigas Group Procurement Policy and the Daigas Group Procurement Policy for Suppliers. In FY2021, the survey was carried out of 33 gas appliance makers to assess the status of their efforts for a total of 59 items on the eight themes of compliance, human rights, labor, occupational health and safety, product safety and quality, environmental conservation, ethics and prevention of corruption, and policy enforcement system. In addition, we conducted a survey of 232 service companies and engineering firms to which the Company has entrusted certain business duties, and nine LNG suppliers.
We will continue to fulfill our social responsibility in partnership with our suppliers and aim to promote mutual development for the entire value chain.
