Delta considers sustainable challenges and opportunities that can be implemented based on the nature of its business. It conducts materiality analysis regularly and has developed the three steps of identification, analysis, and confirmation through the principles of inclusiveness, materiality, and integrity of the GRI Standards. Delta confirms and adjusts sustainability issues regularly. It has set long-term sustainability goals while regularly reviewing the status and effectiveness of implementation through internal key performance indicator review, external international sustainability ratings, and comparison of peer performance, as well as proactively disclosing the effectiveness of the implementation to the public.
Six major stakeholders
The identification of sustainability issues starts from factors that may affect the company's sustainable operations, including internal and external risks and opportunities in the economic, environmental, and social spheres.
Delta has compiled and integrated its sustainability issues based on international sustainability norms and standards (GRI Standards, ISO26000 Guidance on Social Responsibility, the RBA Code of Conduct, and UN SDGs), sustainability ratings (Dow Jones Sustainability Index, CDP, and Morgan Stanley ESG index), stakeholders' expectations and communication, internal business goals, and the sustainability information disclosed in the past. Delta's six major stakeholders and 20 major sustainability issues have been identified through a sustainability consensus meeting.
Selection of 11 key sustainability issues
Based on the 20 sustainability issues identified in the first stage of identification, Delta has adhered to the two principles of "degree of stakeholders' concern" and "impact on operations," and prioritized the issues to determine the criticality of each issue.
Regarding the "degree of stakeholders' concern," Delta conducted an online questionnaire survey, with six major types of stakeholders as the participants of this survey for the purpose of collecting a representative sample. As for "impact on operations," it evaluated the impact of each issue on business-related factors such as revenue growth, environmental sustainability, customer satisfaction, and the best employer. The sustainability task force members worked together to complete the evaluation of the impact of each issue on Delta's operations.
Based on the analysis results above, Delta has selected 11 key sustainability issues, with the rest being its potential sustainability issues, after discussions among the ESG Committee, external experts, and senior executives, and confirmation with the board of directors.
