The NTT Group strives to preserve ecosystems.

Why does the NTT Group strive to preserve ecosystems?

Animal species such as the reindeer and the giraffe are said to be on the brink of extinction.

The scale of the impact of human activity on our planet is now too great to be ignored.

The rate of species extinction has increased 1,000-fold.

Wholesale destruction of nature will decimate our food and water resources and bring an end to the human race.

If we are to remain on this planet, we need to start incorporating environmental considerations--in particular, conservation of ecosystems--into the way we do business, so that we can all continue to enjoy that which nature provides.

ICT has countless benefits, but we must never lose sight of the bigger picture about ecosystems.

*It lists 24,307 of 85,604 species under threat of extinction.

How does ICT contribute to the preservation of ecosystems?

The NTT Group is pursuing a range of ICT-driven initiatives to contribute preserving ecosystems.

For example, in addition to ecosystem research, we have set up donation systems on selected ICT services where a donation is made to environmental groups whenever the service is used a given number of times.

We are also working with our employees, customers and local communities on tree-planting and afforestation programs that directly benefit local ecosystems.

We believe that these programs play an important role in educating young children about the importance of ecosystems.

The NTT Group is actively working on a range of initiatives geared towards preserving ecosystems.

Preservation of the Earth's ecosystem.

Ecosystems (biodiversity, food and water, environmental adjustment and scenery) provide us with the bounty of nature. Through a range of activities undertaken by all the people involved in the work of the NTT Group (providing advanced technology, providing telecommunications services, mobilizing employees), we are putting effort into the conservation of ecosystems.

What are these initiatives?

We have set up a donation system on Midori-no-goo that sends donations to environmental groups in accordance with the number of searches performed or page views of news and other content.

The NTT Group also contributes to conservation programs that use the most advanced ICT services and technologies for work such as studying the habitat conditions of rare plant and animal species.

Our employees are involved in a variety of conservation initiatives around the country, including tree-planting programs and conservation work in remote and rural areas.

Monitoring the habitat of a rare fish species

The NTT Group has developed a general-purpose remote environment monitoring system* that can be set up almost anywhere. It is currently being used to study the habitat and growth patterns of the Japanese Rose Bitterling, a rare species of fish. Through real-time monitoring, scientists are able to gather highly useful information on the environmental conditions conducive to growth**.
