Materiality (key challenges) identification process

At our company, we have established Corporate Sustainability Office within the Corporate Planning Department as a dedicated organization for sustainability. This office regularly identifies sustainability-related risks and opportunities across our group's business segments and value chain, and conducts materiality assessments. materiality assessment is based on the concept of "double materiality * We conduct our research from the perspective of "[...] and for each risk, we take into account future business environment assumptions based on scenario analysis, and extract materiality based on three elements: (a) financial impact, (b) likelihood of occurrence, and (c) short-term, medium-term, and long-term time axes, through interviews with external experts and discussions at management meetings.

*This approach examines the importance of environmental and social issues from both the perspective of their financial impact on a company (financial materiality) and the impact of corporate activities on environmental and social issues (impact materiality).
