Corporate citizenship activities

Based on Management Philosophy of "Truly inspired," Idemitsu Kosan has formulated guidelines for promoting corporate citizenship activities and is engaged in a variety of corporate citizenship activities to help make the lives of people in the countries and local communities in which it conducts business more fulfilling and peaceful.

By 2022, we have clarified the significance and purpose of our corporate citizenship activities, the priority areas of our activities, and what we value in line with Management Philosophy and vision, and in order to realize personal growth and contribution to society through our activities. We have formulated the following corporate citizenship activities promotion guidelines

Munakata City and Idemitsu Kosan Collaborate on Munakata City Beach Cleanup and Marine Plastic Recycling

To contribute to solving the marine plastic waste problem and realizing a Resources recycling society, we are collaborating with Munakata City in Fukuoka Prefecture, a place associated with our founder, Sazo Idemitsu, to promote community-based environmental activities. Since 2023, our group employees, participants from our dealers, and Munakata City officials have worked together to conduct beach cleanup activities, collecting marine debris that has washed ashore on the coast of Oshima Island in Munakata City.
During beach cleanup activities, we emphasize the importance of participants themselves separating recyclable plastics from the collected marine debris and recycling them as Resources. The conversion of the separated plastics into oil was carried out jointly by Environmental Energy Co., Ltd. and its joint venture with our company, Chemical Recycle Japan Co., Ltd. (renamed “Idemitsu Chemical Recycle Japan Co., Ltd.” as of October 1, 2026). Using our unique chemical recycling technology, we processed the plastics into oil, producing recycled oil (CR oil*) that can also be used as a raw material for plastics. The generated recycled oil was donated to Munakata City and is being utilized within the community. A key feature of this activity is that it goes beyond simple litter picking, encompassing "collection," "sorting," "Resources recovery," and "local utilization" in a consistent manner. By leveraging the human resources and technology of our group and collaborating with the local community, we are realizing a sustainable Resources recycling model.

This initiative won the Gold Award, the best example, in the "Picking Up" category of the "Plasma Award 2026" sponsored by the Ministry of the Environment.

Sodegaura City and Idemitsu collaborate to revitalize rural landscapes and reduce CO₂ emissions through biochar (bamboo charcoal) production.

In February 2026, we co-hosted a "Biochar (Bamboo Charcoal) Production" workshop with Sodegaura City, Chiba Prefecture, at Advanced Technology Research Laboratories (Hirakawa Ground).
Neglected bamboo groves are a local issue that damages the environment of rural landscapes. By carbonizing the felled bamboo to create biochar, CO₂ that would otherwise be released into the atmosphere through decomposition and combustion can be fixed as carbon. This time, we produced approximately 340 kg of bamboo charcoal, which translates to a CO₂ reduction of approximately 612 kg. On the day of the event, all participants experienced everything from felling the bamboo to making the charcoal, making it a learning opportunity to deepen their understanding of the significance of biochar production and carbon neutrality.

As a responsible corporate citizen, we will continue our activities to nurture the emotional well-being of the next generation while maintaining close ties with the local community. This will contribute to a more vibrant future for the community.
Transforming human energy into societal energy. Through cultural activities such as the "Idemitsu Music Award," we connect people, communities, and future generations.

At Idemitsu Australia (Brisbane), we are pursuing initiatives that contribute to solving local social issues from a long-term perspective, based on four management-level policies: "Environmental Management," "Energy Management," "Cultural Heritage," and "Stakeholder Engagement." Furthermore, our group is also developing corporate citizenship activities at our business locations in each country and region that are tailored to the challenges and needs of each local area.
