Basic Approach

The operations of the ENEOS Group may impact the environment surrounding our operation and production sites. Given the nature of our business, we consider biodiversity conservation to be an important effort, as stated in the ENEOS Group Code of Conduct.
We carry out initiatives with attention to biodiversity in all aspects of our business activities. These initiatives include the implementation of environmental impact studies when establishing new operation and production sites in order to obtain an accurate understanding of local ecosystems, including plants, birds and other animals, and marine life.
For information on our structure, see Environmental Management.
For information on our targets, see the Medium-Term Environmental Management Plan.

Major Initiatives in Japan

As part of its efforts to preserve biodiversity, ENEOS, which has many production sites, has established the Energy Group* Guidelines on Biodiversity, and it also carries out activities for the preservation of vibrant biodiversity as one way of participating in community efforts to preserve biodiversity and maintaining ecosystem networks in the large nearby green areas.
At our other business sites as well, we carry out environmental conservation activities suited to the surrounding environments.
We also carry out activities such as regular environmental training for employees and community contribution activities related to environmental conservation.

Initiatives at the ENEOS Chita Plant

Nature observation walk organized for local children by the NPO Japan Ecologist Association of Support

The ENEOS Chita Plant is a member of the Ecological Network Formation and Leadership Development Program for Corporate Green Spaces in the Coastal Area of Chita Peninsula and the Project Linking Life with One Another. These initiatives, which involve partnerships among local governments (Aichi Prefecture, Chita City), NPOs, students and companies located in the coastal area, utilize corporate greenbelts and other areas to provide safe and secure habitats for local flora and fauna.
The plant is working to mainstream biodiversity through measures such as ecosystem surveys (monitoring) of its biotope, conducted with students in the local community. As a result of these activities, the Chita Plant was granted certification by the Association for Business Innovation in Harmony with Nature and Community® (ABINC)* in 2015. This certification was renewed in 2018.
In fiscal 2019, in addition to the biotope, the plant conducted ecosystem surveys (monitoring) on four occasions of the wildfowl and raptors living in the greenbelt. In addition, the plant hosted a nature observation walk, organized by an NPO.

Initiatives at the ENEOS Negishi Refinery

Interactive event

The ENEOS Negishi Refinery is one of Japan's largest oil refineries, with an area of 2.2 million square meters and a circumference of around 12 kilometers. The area in which it is located has a network of ecosystems with a diverse array of organisms inhabiting an expansive greenbelt that includes Sankei-en and Negishi Forest Park. Under the concept of creating a satoyama, the Negishi Refinery carries out activities for the conservation of biodiversity utilizing the greenbelt (approximately 60,000 square meters), a hub for the area's ecosystem network, at the center of the premises.
Ecosystem surveys were begun in fiscal 2013, and in surveys to date, 170 types of living organisms have been observed, indicating that many organisms use this grassy area as their habitat.
From fiscal 2018, we held interactive events and weeded the greenbelt areas using goats. In fiscal 2019 and beyond, we will step up maintenance and management of the green areas, and we will also enhance our activities there through efforts such as extending goat grazing periods and hosting new events.
As a result of these activities, the Negishi Refinery was granted certification by ABINC* in February 2020.

ABINC certification mark
  • * ABINC certification is awarded on the basis of the JBIB Guidelines for Sustainable Business Sites and the JBIB Land Use Scorecard developed by the Japan Business Initiative for Biodiversity (JBIB).

Forest Stewardship and Afforestation Activities

ENEOS Group companies are involved in forest stewardship activities that contribute to the preservation of biodiversity.
ENEOS implements forest stewardship activities called ENEOS no Mori at six locations across Japan in partnership with local governments and the National Land Afforestation Promotion Organization (NLAPO).
Since 1998, JX Nippon Oil & Gas Exploration has implemented a forest stewardship project called JX Nakajo Forest for the preservation of pine trees on and around the site of its Nakajo Field Office in Niigata Prefecture. The company was recognized for these initiatives with the 3rd Infrastructure Maintenance Award (Ministry of Agriculture, Forestry and Fisheries; category for activities supporting maintenance) in September 2019.
JX Nippon Mining & Metals is also working to maintain and improve the natural environment by continually engaging in afforestation activities such as tree planting and thinning, mainly at the sites of its closed mines.

Ordering a menu item at the employee cafeteria

Since 2019, ENEOS Holdings has been offering sustainable seafood* menu options once a month at the ENEOS Building employee cafeteria, used by the Company and its Group companies.
Through this initiative, we are working to raise awareness about biodiversity conservation and environmental conservation among Group employees through food, a part of everyday life.

  • *The seafood has met the MSC's global standard for sustainability or ASC's global standard for responsibly farmed seafood.

Major Initiatives Overseas

Tree Planting Activities at the Caserones Copper Mine

Flora found around the Caserones Copper Mine

At the Caserones Copper Mine in Chile, 48,200 seedlings of 15 native flora species are being planted in an area spanning 1.43 square kilometers to protect biodiversity. The areas being planted are those around the Ramadilla River area on the mine site, and the off-site areas around Maitencillo and Amolanas. Completion is slated for 2021.
In addition to planting, efforts are also being made to monitor the native flora and to research the correlation between the propagation and distribution of unique alpine flora located around the mine and the impacts of climate.

Measures for Ballast Water (Seawater)

Oil tankers from Japan bound for oil-producing countries carry ballast water (seawater) as weight to maintain stability for unloaded voyages.
However, this ballast water contains microorganisms and plankton that are carried to the waters of oil-producing countries, where, if released, they can disturb the balance of local ecosystems.
Since 2004, the ENEOS Group has replaced this ballast water while still at sea, and installed water treatment systems* for ballast water on its new vessels in an effort to avoid disturbing the coastal waters of oil-producing countries.

  • *Systems that keep the level of aquatic organisms in ballast water within certain standards prior to release.
