Taipei Metro Supply Chain
The upstream, midstream, and downstream relationships within Taipei Metro's supply chain are illustrated in the following diagram. Supplier categories are primarily divided into three major types: engineering, labor services, and goods. In alignment with national policies on supplier localization and green procurement, Taipei Metro implements sustainable supply chain management through three main action plans.


Implement Sustainable Supply Chain
To achieve a net-zero transition and strengthen the sustainability resilience of its supply chain, Taipei Metro has initiated the establishment of a sustainable procurement management system in accordance with the ISO 20400 Sustainable Procurement Guidelines. This system introduces a systematic management mechanism to enhance the Company's sustainable supply chain management. In 2024, Taipei Metro conducted a specialized training course on the Establishment of Sustainable Supply Chain Management Guidelines. Through this education and training, the professional knowledge and practical skills of internal procurement personnel were comprehensively enhanced, laying the foundation for future system implementation.
In the vendor selection criteria, Taipei Metro includes as a bonus item the willingness to use green products during contract performance (such as cleaning agents, building materials, paper products, electrical appliances, and other green products), supported by documents such as purchase orders, supply certificates, or letters of intent, as well as relevant green product certifications including environmental labels, energy-saving labels, water-saving labels, and green building material labels. Through this scoring mechanism, the Company promotes sustainability concepts among suppliers. In 2024, a total of 60 ESG procurement cases incorporated this evaluation criterion.
Promoting Supply Chain Localization and Green Procurement
To promote supply chain localization and enhance supply chain autonomy and resilience, Taipei Metro, in cooperation with the Railway Bureau of the Ministry of Transportation and Communications, has participated in the localization promotion program under the "Guidelines for the Localization of Railway System Maintenance Spare Parts," striving to reduce reliance on imported original equipment manufacturer components.

Green Procurement
Taipei Metro implements a green procurement policy in accordance with the Executive Yuan's Ministry of Environment's green procurement guidelines. The Company incorporates environmentally friendly products into its procurement of goods and materials, achieving a 100% compliance rate for designated green product items. In addition to green procurement, Taipei Metro has actively implemented digitalization in its procurement operations, completing paperless processes across all procedures and establishing an electronic platform for small-amount procurements to enhance process efficiency and environmental benefits.

Joint Promotion of ESG with Vendors
On March 25, 2024, Taipei Metro held a seminar titled "Essential Strategies for Corporate Sustainability Transformation from a Global Perspective". Suppliers were invited to participate in the event, with representatives from 93 companies and over 100 attendees in total.
Taipei Metro organized first aid knowledge promotion activities with vendors, focusing on the correct use of cardiopulmonary resuscitation (CPR) and automated external defibrillators (AEDs) to enhance passengers' ability to respond to emergencies while riding the Metro.
