In determining materiality, we identified issues to be considered by referring to international guidelines such as the GRI Standards and ISO26000, as well as research items from SDGs and ESG evaluation organizations. Idemitsu group's business activities and environmental and social issues that could be affected by these activities were identified and sorted out into 38 categories. We also conducted a questionnaire survey of internal and external stakeholders, including customers, business partners, shareholders, investors, and group employees, to confirm their expectations.
In the end, we identified six materialities by aligning them with our medium-term management plan, which is our corporate strategy, and taking into account discussions at the management level. Materiality is closely linked to corporate and departmental strategies, and is priority topics in our medium-term management plan.

As an energy co-creation company, we continue to challenge new values creation with various stakeholders. In order to do so, we considered priorities from a long-term perspective, taking into account environmental and social issues, and set them as our priority topics "Materialities."
