Concept for Determining the Materiality of Issues
1. Confirmation of coverage and selection of issues
We have selected 16 sustainability issues that NTT DOCOMO should address by reviewing external evaluations, guidelines, the NTT Group Sustainability Charter, and other topics related to sustainability.
External indicator: DJSI
International guidelines: GRI Standards, SASB, ISO26000
Domestic and overseas initiatives: SDGs
2. Priority assessment
With regard to the sustainability issues selected in 1., we evaluated our priorities based on two perspectives: social impact (external impact, such as to stakeholders) and business impact (impact within NTT DOCOMO), with input from outside experts, in order to identify sustainability issues that are considered to be of high priority to NTT DOCOMO. All of the 16 issues were rated high priority.
3. Materiality assessment and validation of issues
Regarding the 16 sustainability issues rated high priority in 2., we summarized the relevant issues, indicated the direction to be taken, assessed their materiality, and designated them as key issues. In addition, we validated a series of processes.
