Social Challenge 3
A future where people and nature are in harmony
Why it matters
The NTT Group's businesses have an impact on ecosystems. For example, the telecommunication equipment essential to our business operations, particularly telephone poles and communications cables, is installed in the natural environment. At the same time, we are sometimes affected by the ecosystem, for example cables are bit and damaged by squirrels or crows. Ecosystems full of biodiversity provide the bounty, such as water and food, which is critical to supporting all forms of life on earth, and thus require a proper approach for conservation.
What can be accomplished
Through our business and employee activities, we will promote initiatives related to conserving ecosystems within nature, in order to ensure that nature is left untouched for future generations.
Future vision
The NTT Group is working to preserve the ecosystems, which are the foundation of society's activities, while also conducting environmentally friendly business activities that take into consideration the mutual influence between ecosystems and the NTT Group.
Business Activity 10
Thoroughly implementing environmental assessment
Our commitment
Implementing environmental assessments during the construction of data centers and other buildings
Our objective
The NTT Group adheres to its Green Design Guideline for Buildings when constructing new data centers or other buildings, and endeavors to reflect the necessary aspects in the facility's design.
Background and Concepts
Communications equipment, data centers and other buildings as well as solar panels required for the NTT Group's business activities present an impact on the environment. In light of this, facilities are designed to minimize impact on the ecology.
Environmental Assessments during the Construction of Data Centers and Other Buildings
When planning to construct new data centers or other buildings, we research the historical, social, geographical, biological, and environmental attributes of the prospective building site and surrounding district based on our NTT Group Green Design Guideline for Buildings, and endeavor to reflect the necessary aspects in the facility's design. For example, we use native plant species as vegetation for greening our data centers, which have in recent times become the core components of ICT infrastructure.
When drawing up proposals for the construction of new data centers for customers, the NTT Group applies the Comprehensive Assessment System for Built Environment Efficiency (CASBEE*1) and submits proposals designed to obtain the highest CASBEE rank of S. While paying due consideration to the environment in this way, we also take care to minimize noise and vibration and maintain the scenic appeal of the district during construction while endeavoring to ensure that exhaust heat and noise from the air conditioning outdoor units and emergency generators of functioning data centers will have minimal impact on neighboring areas.

NTT Urban Development
Shinagawa Season Terrace acquires "ZEB Ready" certification
Compared to standard buildings, Shinagawa Season Terrace is able to reduce its annual primary energy consumption in its office areas by 51% (43% for the entire building), and acquired the top 5 star rating in the Building- Housing Energy-efficiency Labelling System (BELS) and ZEB*2 Ready" certification in December 2019 for the office area that is its main application. Featuring atriums filled with natural light and wind, a heat discharge system using cool external air, air-conditioning using a sewage heat recovery system, recycled water, and more, Shinagawa Season Terrace is one of the highest standard environmentally friendly office buildings in Japan, with eco designs and facilities offering excellent comfort and energy efficiency.
- CASBEE: A system for the comprehensive assessment of the quality of a building from such perspectives as environmental performance, interior comfort, and scenic appeal
- ZEBs are defined as buildings using advanced architectural designs that aim to realize substantial energy savings while maintaining the indoor environment by (1) reducing the energy loads, (2) positively utilizing natural energy by applying passive technologies, and (3) introducing high efficiency equipment and systems. They additionally aim to achieve the highest degree of energy independence and reduce the annual primary energy balance to zero by (4) introducing renewable energy.
Business Activity 11
Contributing to natural ecosystem conservation
Our commitment
Business activities that contribute to preservation of the Ecosystem
Our objective
The NTT Group is working on activities that contribute to preservation of the ecosystem by harnessing our information dissemination capabilities.
Background and Concepts
As a company providing ICT services, we are working on contribution activities that harness our information dissemination capabilities. The guidelines that apply to various business types and industries within the NTT Group outline the requirements for materials used for business activities. This applies to procurement and purchasing activities conducted at each business site within the NTT Group, as part of efforts to switch over to renewable energy sources and forest certified paper, which has a low environmental impact. Compared with the adverse effects on ecosystems caused by mining fossil fuels or global warming, renewable energy sources are deemed to have minimal negative impacts. The NTT Group operates services that supply both corporate and private customers with power from renewable energy sources, as it aims to run business activities that reduce the impact that society as a whole has on ecosystems.
Business Activity
NTT DOCOMO
Sea turtles returning the favor
As part of initiatives aimed at the conservation and restoration of biodiversity, NTT DOCOMO is involved in establishing and promoting world natural heritage site community initiatives aimed at environmental conservation and regional development around Amami and Okinawa. Together with regional government bodies and local universities as well as local companies, we are also involved in regional contribution and revitalization activities to take advantage of rare species and the natural environment, with the aim of registering world natural heritage sites and establishing a recirculation model for environmental conservation and regional development. Addressing the problem of marine debris is a key environmental conservation initiative in Okinawa Prefecture, and NTT DOCOMO is taking part in activities alongside local organizations. A marine debris collection drone was constructed as part of this initiative, as the collection of floating waste had the potential to assist with cleanup activities and reduce the impact on marine life.
The drone is operated using a smartphone, with a live video feed from a camera installed on the drone providing a more intuitive approach to debris collection. Plastic waste collected from local cleanup activities was recycled by pressing it into plastic sheets for use as the outer shell of the sea turtle.
A seagull-shaped drone has also been made to help search for marine debris from up in the air. A similar camera setup as the sea turtle-shaped marine debris drone provides a live video feed from the air direct to smartphones. This makes it much easier to search over wide areas along the coast that are difficult for people to access.
