Based on the five-step identification process, 24 sustainability topics were selected in the first step (one more than last year Note). An online questionnaire survey and online seminar were used to understand the level of influence of the topics on stakeholder assessments and decisions (Y-axis) and external stakeholders’ view of TWM’s impact (bubble size) on society for each topic. Then, the ESG Steering Committee confirmed the importance of each topic to Taiwan Mobile's operations (X-axis) and the impact of Taiwan Mobile on society (bubble size) via resolutions. Finally, the Taiwan Mobile’s material topics are identified based on the X-axis and Y-axis scores and bubble size for each topic.
Based on the results of the material topic matrix, we further identified the key topics for Taiwan Mobile. We gave priority to the topics that were most important to the Company's operations, concerned stakeholders the most, and in which the Company had a strong impact on ESG, including green applications and the circular economy, climate change mitigation and adaptation, network quality and coverage, information security, privacy protection, and technology innovation & applications. We also considered topics that the Company would manage internally in an autonomous manner. The Company confirmed that it should invest in long-term sustainable management with its supply chain, so supply chain management was included among the key topics. There were a total of eight key topics for TWM in 2021, which can be seen in the diagram below.
