Determination of Material Topics |
To maintain effective communication with stakeholders and meet their request for sustainability information, UMC conducts materiality analysis.
Step 1: Understand UMC's Organizational Context |
Understand links between UMC's activities, business relationships and the sustainability context in which these occur. Identify its important stakeholders through the overview aforementioned.
Step 2: Identify Actual and Potential Impacts |
According to UMC’s self-developed materiality analysis methodology, in the process of determining materiality topics, we undertake inventories to assess the actual and potential positive/negative impacts caused by UMC ‘s activities and business relationships on the economy, environment, and society
(ESG True Value Evaluation), as well as these impacts on the Company’s operation, which covers the concept of Double Materiality. Through impacts description, the Company is able to define the possible impact patterns, and where they occur in the value chain.
Step 3: Assess the Significance of the Impacts |
Conduct questionnaire surveys to quantity the impact assessment of materiality. Survey of stakeholders’ concerns
(1) Management representatives
(2) Team members of Sustainability Report Preparation
Industry major issues concerned by the international rating were also considered as weighting weights while external expert consultants reviewed the results of the surveys in order to keep in line with international trends. Each sustainability issue has a pair of score, the degree of severity and the likelihood of occurrence, respectively as the value of X-axis and Y-axis.
Step 4: Prioritize Significant Impacts |
A materiality matrix is created with the degree of severity as the X-axis and likelihood of occurrence as the Y-axis to analyze the significant of sustainability impacts in order to prioritize the significant impacts. The material analysis result was confirmed after being submitted to and approved by the CSO.
Step 5: Management and Disclosure |
The results of materiality analysis will serve as a reference for the Company to determine short-, medium- and long-term Sustainability Strategy Blueprints and Goals, to ensure that relevant strategies and goals encompass the expectations of stakeholders, and have responded to the identification and management of sustainability impacts. Moreover, the Company continues to develop and assess relevant procedures to integrate material assessment, which might identify
significant impacts, into the Company's enterprise risk management system and framework, which shall be regularly reviewed.
In principle, UMC conducts materiality analysis every two years, and carries out flexible discussions about and reviews of material topics on a yearly basis depending on actual needs or external stakeholder engagement results, to ensure that the Company's operations are in line with actual trends and meeting stakeholders' expectations.
