Stakeholder Engagement

Stakeholders

PTI releases annual reports on the corporate governance, economic aspects, environmental aspects, social aspects, and other subjects. ESG Report is also published annually with clear disclose of ESG-related information. These topics are communicated to the stakeholders transparently, timely, and completely through the use of the company website, PTI ESG fan page, and other social media communication platforms.

Stakeholder Identification

PTI's Sustainability Management Office has formed the "Sustainable Development Task Force" with personnel from relevant departments, including finance, procurement, occupational safety, plant engineering, human resources, quality control, sales and research and development to review and identify six categories of stakeholder groups, which are shareholders/investors, employees, customers, suppliers/contractors, government agencies, and communities, based on all groups or individuals that may be affected by our operations or be concerned about the company's sustainable development performance, with reference to the five major principles of the AA1000SES Stakeholder Engagement Standard.
