In 2023, we conducted Arkas Line Sustainability Materiality Analysis through interaction and dialogue with our internal and external stakeholders to identify our sustainability priorities and key issues. We defined sustainability priorities as topics that significantly impact Arkas Line’s operations or fall within Arkas Line’s sphere of influence. In this study, we considered both direct and indirect effects, as well as positive and developmental impacts. We conducted the sustainability prioritization analysis through Stakeholder Mapping, Prioritization Analysis List, Stakeholder Survey, One-on-One Meetings with Selected Stakeholders, and Top Management Sustainability Priorities Workshop.
