The Process of Compiling

We place great importance on the process of compiling this report. The process is designed with the aim of improving transparency and reliability as a company, in the interest s of accountability, and of tying in with ESG activities carried out by group companies.

Improving Transparency and Reliability

Having examined and identified ten “material issues” from the perspectives of our stakeholders and management, they provide the basic framework for both our ESG activities and ESG reports. As the environment is constantly changing around us, not least in terms of stakeholder trends, we review our material issues on a regular basis. We also keep a close eye on matters of interest to our stakeholders, their expectations and business conditions, so that we can check and adjust the contents of our reports in precise detail.
To keep track of matters of interest to our stakeholders, their expectations and other related trends, we gather information from individual departments, based on sources such as questionnaires from SRI agencies and ESG investors, responses to reader questionnaires, and intensive internal interviews prior to the compilation of the current report. We hold Stakeholder Meetings to discuss topics of particular importance. Meetings also help to establish a clear understanding of social issues, from various different angles, and to examine details of group initiatives.
We also obtain an “independent assurance,” to assist in comprehensively evaluating the contents of our report against international requirements in an effort to improve transparency and reliability.

Promoting ESG Activities based on Communication

We make the most of communication activities, as part of the process of compiling this report, to improve our ability to promote ESG activities, by establishing a shared understanding and raising awareness of changes in the external environment for example.
The Corporate Communications Dept., which oversees our ESG activities, conducts hearings with the relevant corporate and company departments as needed, and not only coordinates the reporting, but also exchanges opinions and shares information about matters of interest or concern to stakeholders, issues for the future, and the direction of our activities.
Asking relevant departments to produce articles for this report, and then exchanging opinions regarding the draft report once it has been compiled, enables departments to review their ESG activities from an external perspective and helps to develop a shared understanding of their strategic significance.
