To respond to the revision of GRI Standard 2021, which stipulated that the report published from 2023 shall comply with the latest GRI provisions, and that the identification of material topics shall be assisted by external and internal experts, this year, the distribution of questionnaires used for the identification of material sustainability topics was canceled and the meeting to consult and discuss with internal and external experts was held instead. After the assessment of the potential and actual positive and negative impacts on economic, environmental and social aspects as prescribed in the GRI Standards, the prioritization and boundaries of the material sustainability topics for 2022 Sustainability Report were determined.

A total of 26 material sustainability topics were identified this year.
