Communication with Stakeholders
TSC values stakeholder engagement and, with reference to the five principles of the AA1000 Stakeholder Engagement Standard (SES), has identified seven major stakeholder groups: suppliers, customers, employees, investors, government agencies, media, and the general public. Through both regular and ad-hoc multi-channel communication with stakeholders, TSC seeks to understand the actual and potential impacts of its operations on these parties, using the insights gained as a basis for planning future preventive and mitigation measures. The results of stakeholder communication are reported annually to the Board of Directors by the Board Secretariat.

Material Topic Identification
TSC follows the Global Reporting Initiative (GRI) Standards to establish its analytical process, conducting materiality analysis through four key steps: identification, evaluation, analysis and validation, and confirmation. This process assesses the actual and potential economic, environmental, and social impacts of its business operations, serving as the basis for planning and adjusting sustainability management strategies.
In 2024, TSC collected 44 valid internal and external stakeholder questionnaires to better understand stakeholder concerns. TSC will continue refining its materiality assessments and communication mechanisms. In 2024, six material topics were identified:
- Business Ethics and Integrity
- Sustainable Supply Chain
- Innovative Product Management
- Water Stewardship
- Climate Strategy and Energy Management
- Occupational Health and Safety
2024 Material Topic Matrix
In response to the GRI Material Topics 2021, TSC considered industry characteristics, geographic location, and organizational context to define both the positive and negative impacts of each sustainability issue. Using a risk management perspective, the significance of actual and potential impacts was identified.
TSC determined material and foundational topics based on the results of questionnaire scoring, which were aggregated through multiplication, weighting, and ranking, and visualized in a materiality matrix. The matrix uses the positive X-axis to represent “degree of positive impact,” the negative X-axis to represent “degree of negative impact,” the Y-axis to show “likelihood of occurrence,” and the Z-axis to indicate the “level of stakeholder concern.”
Material Topics Implications
Positive/Negative Impact and Implications
Sustainable product innovation: Integrate sustainability into product design and production by adopting new technologies, using non-hazardous materials, and applying low-pollution, energy-saving processes. Strengthen hazardous substance management, identify recyclable materials, and promote circular design to minimize environmental impact.
