Stakeholder Engagement

We believe that in-depth communication with stakeholders is the foundation for sustainable management, and well-planned and effective communication can understand the topics that concern stakeholders. Therefore, apart from constantly establishing communication channels, we focus on and address issues that concern stakeholders, discuss their influence at different types of meetings and include them in the company's short-, medium-, and long-term strategies, such as the five-year plan and risk and opportunity management policies. We also adjust the directions of sustainable operations, and report to the board regularly.

Referring to the attributes of stakeholders as specified in AA 1000 SES: dependency, responsibility, influence, diverse perspectives, and tension, we identified 7 major stakeholder groups for communication in the 2024 report: employees, customers, shareholders / investors, government agencies, suppliers/contractors, peers, and local communities/residents, with peers being added as a key stakeholder compared to the previous survey. Besides gathering stakeholder opinions from various channels, we have also set up the ESG section on the corporate website to enhance communicability.
