Promotion of Green Purchasing

Aspects Determained as Materiality
  • Supplier Environmental Assessment


Principle and Outline

The Daigas Group has declared that it will achieve the advanced use of resources and materials in the Daigas Group Charter of Business Conduct and the Daigas Group Code of Business Conduct. The Group has also set environmental targets, including those of reducing CO2 emissions, facilitating the more widespread use of renewable energy, reducing waste and accelerating waste recycling, and reducing the amount of excavated soil for final disposal. Aiming for these targets, the Group is implementing measures to reduce the impact of its business activities on the environment. As part of these efforts, Osaka Gas has been pursuing “green purchasing,” the procurement of environmentally sustainable goods and contract works from business partners actively committed in environmental conservation.

Based on its Green Purchasing Guidelines (formulated in 2000, revised in 2020), Osaka Gas works with business partners to promote Green Purchasing: prioritized procurement of biodiversity-friendly goods and construction work that have less impact on the environment. We actively use eco-friendly products, including Forest Stewardship Council-certified paper, recycled paper, LED lighting, and carbon offset products.

In 2005, we launched the “Green Partner Initiative” to evaluate environmental efforts by our main suppliers, including establishing an environmental management system (EMS) and obtaining an EMS certificate. Suppliers recognized in support of the initiative have been registered as Green Partners.

The Green Partner Initiative was revised in FY2016, resulting in suppliers other than those supplying piping materials now being covered by the initiative. As of March 31, 2021, 110 suppliers are registered. Affiliates are working to expand green purchasing under the Daigas Group Environmental Management System (OGEMS), the Daigas Group’s unique environmental management system.
