Supply Chain Communications, Social Welfare and Development

In recent years, TWM has persistently worked hand in hand with suppliers to promote sustainable development through diverse communication and collaboration channels, deepening partnerships. TWM organizes training programs, workshops, and exchange sessions to deepen suppliers' understanding of sustainability issues and equip them with practical ESG execution capabilities.

In response to the global trend of carbon management evolving from simple emissions reduction to nature-based solutions and climate risk governance, TWM actively aligns with international sustainability standards, including SBTi, TNFD, and IFRS S2. Through multiple engagement mechanisms—such as supplier workshops, decarbonization workshops, and sustainability forums—TWM continues to enhance supply chain carbon management capabilities and climate resilience.

As of the end of 2025, TWM had guided 46 suppliers to set science-based decarbonization targets following the SBTi pathways, achieving an average carbon emissions reduction of 3%. Biodiversity requirements were fully incorporated into engineering procurement contracts, promoting shared responsibility for nature-positive outcomes across the supply chain.

In 2025, TWM organized one SBTi Precision Decarbonization Workshop, inviting 27 suppliers with high decarbonization potential. The workshop covered corporate decarbonization practices, global net-zero trends, SBTi pathways for SMEs, and practical SBT tool applications. Expert consultants provided professional guidance, while participating companies shared practical experiences, helping suppliers strengthen their planning and implementation capabilities and improving overall supply chain decarbonization performance.

Looking ahead, TWM will continue to support suppliers in setting science-based decarbonization targets, advancing toward the 2035 milestone of a 23% reduction in supply chain emissions.

Furthermore, TWM has consecutively received the highest A rating in Supplier Engagement from the Carbon Disclosure Project (CDP) for four years, achieving full marks across all four evaluation indicators, demonstrating TWM's commitment and leadership in co-creating a resilient, green ecosystem across its industry value chain.

In 2025, TWM successfully engaged XX high-carbon-emission suppliers to participate in a green power group purchase program, accelerating the adoption of renewable energy and continuously promoting suppliers' green transformation. At the same time, TWM encouraged suppliers to join the "Planting Green Power" initiative, extending its sustainability impact from energy transition to tangible social contributions. To date, 160 suppliers have participated in this program.

Through the green power group purchase and engagement activities in 2025, TWM supported the installation of solar panels for non-profit organizations on third-party rooftops, with a planned fundraising of NT$4.5 million. Over the next 20 years, the initiative is expected to generate approximately 2.15 million kWh of green electricity, providing the Hsinlu Social Welfare Foundation with an estimated NT$7 million in revenue while simultaneously reducing carbon emissions by around 1,020 tons. These efforts not only strengthen supply chain energy management and carbon reduction capabilities but also extend corporate sustainability actions to social well-being and practical public value.

TWM continues to leverage innovative approaches in collaboration with suppliers to develop green energy, driving carbon reduction and shared social value, demonstrating leadership and commitment in energy transition, corporate social responsibility, and sustainable supply chain management.

To address climate change and coastal risks, Taiwan Mobile incorporates nature-based solutions into its supply chain climate strategy and collaborates with suppliers to promote mangrove restoration, building a blue carbon ecosystem with both carbon sequestration and disaster resilience benefits. In 2025, the Chief Financial Officer personally led Tier 1 and Tier 2 supply chain partners in mangrove restoration activities, integrating natural capital and climate resilience into corporate risk management and supply chain governance.

Through these actions, Taiwan Mobile transforms sustainability commitments into tangible practices while strengthening suppliers' capabilities in climate and nature-related management. For further details, please refer to Section 5.3.1 Taiwan Mobile Blue Carbon – Mangrove Restoration Program.
