Stakeholder Engagement

Stakeholder Engagement

TSMC established a systematic model for materiality analysis in line with the GRI Standards and AA 1000 Stakeholder Engagement Standards (SES). Incorporating three phases and seven steps, the analysis is conducted to create TSMC's materiality matrix, and serves as a foundation for further developing TSMC's sustainability strategy and its short-term, medium-term, and long-term corporate sustainability goals. Materiality analysis is also an important reference for identifying material issues to be disclosed in the Company's Corporate Social Responsibility (CSR) Report.
