Mechanisms for Stakeholder Communication

To maintain effective communication with stakeholders and meet their request for sustainability information, UMC conducts materiality analysis.

Step 1

Collect sustainability issues

Adopt the GRI G 4.0 guidelines, ISO 26000 social responsibility standard guidelines, UN Global Compact and domestic and international sustainability assessments as basis for issues.

Step 2

Compile sustainability issues

Members of the Corporate Sustainability Committee Report Group compile and analyze issues.

Step 3

Survey stakeholders concerns

Conduct questionnaire surveys to determine the degree of stakeholder concern over the various types of sustainability issues so that stakeholders can express their needs in terms of sustainable information.

Step 4

Analyze impact of issues on company operations

The Sustainability Report Group analyzes the impact of issues on company operations sustainability, and screens for materiality issues.

Step 5

Rank materiality issues

Multiply the score for degree of stakeholder concern over each issue and the score for its respective impact on company operation. Rank issues for disclosure.

Step 6

Discussion and review

1. Following materiality analysis, the company discusses and decides on the disclosure ranking of sustainability issues.
2. The Sustainability Committee shall conduct management review for material issues related to the economy, environment, and society.

The CS committee annually reviews the concerns of important stakeholders and relative issues. Each committee then proposes suitable solutions
