Policy on Reporting Sustainability Activities

The Daigas Group deems that it is necessary for the Group to listen to people's voices sincerely, and conduct its business activities based on such voices, if it is to fulfill its corporate social responsibility (CSR).
In the Daigas Group Medium-Term Management Plan 2026 “Connecting Ambitious Dreams,” we laid out the key strategy of “co-create value for a sustainable future,” “support employees to shine in their roles,” and “evolve business foundation,” which contribute to solving social issues. We also reviewed materiality.
In identifying the materiality, we referred to the GRI Sustainability Reporting Standards (GRI Standards), a global standard for sustainability reports compiled by the Global Reporting Initiative (GRI), while taking into account current social issues and holding dialogue with outside experts.
This site, the Group explains the management situation regarding materiality and the degree of implementation of relevant measures. The Group posts, as much as possible, activities other than those related to the materiality so that a full picture of the Group's CSR is made known to parties outside and inside the Group.

In selecting topics to be covered in this site and prioritizing them, we took into consideration both the impact on society and the environment and the future financial impact on the Group.
