NTT Group
Sustainability Design Guideline for Buildings

The NTT Group has established the "NTT Group Sustainability Charter" and is promoting various initiatives with the aim of realizing a sustainable society through "growth as corporations" and "resolution of social issues".

In the building field as well, we will contribute to the realization of a sustainable society by designing buildings in accordance with this guideline, which were established based on the Charter's three themes of "Ensuring the coexistence of nature and humanity," "Improving prosperity for all people and cultures," and "Maximizing wellbeing for all."
