Our group recognizes that our business activities both depend on and impact biodiversity. Under our corporate philosophy of "Contribute to the protection of the global environment and the existence/development of humanity, offering the value sought by society," we position biodiversity conservation as a priority management issue. Going forward, we will continue to promote business activities that consider biodiversity, aiming to contribute to the realization of a nature-positive society.

*1 : Nissan Bio-Park Nishi-Hongo

It is a green park comprising a biotope area and a flower garden area, located on approximately 2.5 hectares of land owned by the Toyama Plant. The biotope area is designed to restore lost natural environments by creating a biodiversity space centered around waterfronts and community-based forests that are easy for animals and plants to live in, and is working to breed species such as black medaka and fireflies. Since the opening of the park in 2008, we have been conducting surveys of flora and fauna, and approximately 142 species of insects and 28 species of wild birds have been confirmed.

*2 : Onoda Plant Biotope

It was created by renovating a pond that originally existed in the central plaza of the Onoda Plant. The western side has been developed as a habitat area for various aquatic creatures. Native species have been released in the pond, and rock formations have been constructed in and around the pond to create suitable habitats for these creatures. Additionally, trees bearing fruits favored by birds and insects have been planted. On

the east side, we have created a relaxation area for employees, featuring benches and flower beds planted with seasonal flowers.

* The 30by30 target

This is a national target adopted at CBD-COP15 held in December 2022, aiming to protect and conserve at least 30% of each country's land and sea areas as healthy ecosystems by 2030. Nissan Chemical is a member of the "30by30 Alliance."
