Stakeholder Engagement

Stakeholder Engagement

Each year, TSMC complies with GRI Standards for Stakeholder Inclusiveness, Sustainability Context, Materiality, and Completeness. Through three phases that include identification, analysis, and confirmation, we assess sustainability issues and carry out materiality analysis to align TSMC's strategies for sustainability management with our long-term goals. The GRI Standards also serve as a guideline for compiling our CSR report, allowing us to examine TSMC's current progress in sustainability, promote improvement within organizations, and create shared value for society and TSMC.
