To fulfill TDCC’s vision and strategy for sustainable operations and expand its sphere of influence, the Company not only promotes sustainable practices within its own operations and internal culture, but also seeks to work hand in hand with suppliers to jointly implement ESG (Environmental, Social, and Governance) policies. These efforts aim to uphold high ethical standards, protect labor rights, and promote environmental stewardship.

The Company has established comprehensive grievance mechanisms and channels for suppliers and other stakeholders to report illegal conduct and human rights violations. These include filing complaints through the “Whistleblowing System” section on the Company’s official website, as well as posting posters promoting grievance channels in public areas such as internal and external office floors and security counters, publicly disclosing dedicated mailboxes and telephone numbers. When a complaint or report is received, the Company follows the procedures set forth in the “Whistleblower Case Handling Guidelines” or the “Prevention Plan Against Unlawful Acts During Duty,” and conducts subsequent tracking and post-case handling.

We have promulgated the TDCC Supplier Sustainability Promotion Policy to raise their awareness of the corresponding supplier code of conduct, and all our suppliers (100%) have signed it.

TDCC Supplier Sustainability Promotion Policy

To promote low-carbon operations, the Company continues to prioritize the procurement of products bearing environmental labels, such as air conditioners, dehumidifiers, refrigerators, printers, paper, and other office equipment and supplies. The Company’s energy policy also explicitly states the principle of prioritizing the purchase of energy-efficient equipment and emphasizes the importance of enhancing energy usage efficiency. In addition, to reduce greenhouse gas emissions generated during transportation, the Company actively practices local procurement principles. In 2025, the Company achieved a 100% local procurement ratio.
