Stakeholder Engagement

Stakeholder Identification

TCC attaches great importance to communication with stakeholders. To ensure that the material topics concerned by stakeholders are included in the Company's sustainable development policy and to establish smooth communication channels as well as a transparent response mechanism, TCC refers to AA1000 Stakeholder Engagement Standard (SES) 2015 and the experience of domestic/ international benchmarking peer groups to identify stakeholders who are relevant to TCC's business activities. In addition, a questionnaire on the degree of internal/external impact is issued to stakeholders, material topics are then evaluated and identified according to the following five aspects: the degree of dependence, impact, degree of concern, responsibility, and diverse viewpoints on TCC.

2023 TCC stakeholders' level of concern survey (CH)

Result of Stakeholder Identification

Five types of stakeholders, including government, shareholders, customers/electricity users, and employees to suppliers/contractors/ subcontractors, were identified. These five key stakeholders share a certain degree of impact on TCC's sustainable development. As a corporate citizen, TCC designates exclusive communication channels for each stakeholder. Adopting substantive analysis, the most important topics for stakeholders and TCC are identified. Subsequently, necessary measures are implemented to strengthen the content of information disclosure, serving as the basis for sustainable development.
