Deliberating on IFRS Sustainability Disclosure Standards: Future incorporation of Double Materiality principle for sustainability impact assessment
In 2024, WT began studying the IFRS Sustainability Disclosure Standards and plans to incorporate the Double Materiality principle (including Impact Materiality and Financial Materiality) as the method for sustainability impact assessment in the future. By comprehensively considering sustainability reporting standards (GRI, SASB), international sustainability ratings (MSCI, S&P CSA, CDP), benchmarking of industry best practices, and other factors, we collected relevant sustainability topics. We also evaluated issues of concern to five key stakeholder groups, analyzing potential impacts from business operations and value chain relationships. Through this process, we identified a list of 19 material sustainability topics. In 2022, WT conducted a sustainability topic questionnaire survey to understand key stakeholders’ concerns and expectations regarding WT’s sustainability management, receiving 611 valid responses. In 2024, after reassessing changes in the operating environment, the Sustainability Task Force determined that sustainability impacts remained largely unchanged from 2023. Therefore, we maintained the same sustainability topics as 2023, which serve as the basis for disclosures in this Sustainability Report.
Relevant GRI material topics of the top three issues
The survey results were analyzed to find out the top three sustainability issues of concern for each stakeholder group. WT matched the issues to GRI material topics, and disclosed relevant implementation strategies, managing policies and plans accordingly.

The sustainability impacts were assessed for severity and probability by our Sustainable Development Team members. The severity is evaluated by the levels of positive and negative impacts. An issue involving an actual or potential human rights risk is assigned the highest severity level. With the stakeholders’ degrees of concern for the issues also taken into account, a three-dimensional analysis matrix was created as an impact level assessment tool to continuously track the impacts of the sustainability issues.
12 material issues disclosed in 2024 Sustainability Report
In 2024, WT’s Sustainable Development Team conducted a comprehensive assessment of the economic, environmental, and social operational impacts and their likelihood across the company’s business activities. Following this evaluation, the team decided to maintain the same 12 material issues identified in 2023 as the basis for disclosure in the 2024 Sustainability Report.
Description of material disclosure issues
15 GRI material topics plus 3 self-defined topics
We matched the selected disclosures with the 33 economical, environmental or social topics of the GRI Sustainability Reporting Standards, and identified 15 relevant material topics and the disclosure indicators related to these topics.
Organizational boundary definition for the Sustainability Report
The key disclosure issues were individually reviewed for their respective impacts on WT and throughout the value chain at Sustainable Development Team meetings, where the team members also determined that the organizational boundary of the Report and the definition of impact scope would vary slightly with different issues.
