The 30by30 Alliance for Biodiversity is a voluntary alliance established to achieve the Nature Positive international target of halting and reversing biodiversity loss by 2030. In addition to expanding protected areas such as national parks, Japan has set aside areas that contribute to biodiversity conservation, such as corporate forests outside protected areas, as OECMs (Other Effective Area-based Conservation Measures). The Company was registered as a participating company in April 2022.

“Nationally Certified Sustainably Managed Natural Sites” are areas where biodiversity is being conserved through the efforts of the private sector, etc., and are certified by the national government.
The certified areas are registered in the international database as “OECM (Other Effective Area-based Conservation Measures)”, excluding overlaps with protected areas. “Teine Forest, one of the Materials’ Forests”, a company-owned forest, was certified in October 2023.

The organization was established in 1992, when the Earth Summit (UN Conference on Environment and Development) in Rio de Janeiro was held, to put the ideas of the Keidanren Global Environmental Charter into practice in the field of nature conservation. Through the Keidanren Nature Conservation Fund, the Company supports NGO nature conservation projects, interacts with NGOs, raises awareness, provides information, and disseminates updates to companies and engages in various activities, including making proposals on international biodiversity targets and domestic policies.

Keidanren (Japan Business Federation) has formulated the “Keidanren Declaration for Biodiversity and Guideline,” which sets out the roles that companies should play and guidelines for action toward realizing a society in harmony with nature.
Recognizing that our Group benefits from natural resources such as minerals and water resources in its business activities, and that we are promoting activities that contribute to the realization of a nature-positive society, we endorse the “Keidanren Initiative for Biodiversity Conservation,” promoted by Keidanren.
