Biodiversity Conservation

Basic Philosophy and Environmental Management Biodiversity Conservation Global Warming Prevention Reduction of Waste Prevention of Environmental Pollution Reducing Environmental Impact Through Our Services Promoting and Using Internal Green ICT Site Data

Together with global warming prevention, the preservation of ecosystems, where living things co-exist in an intricate balance, has recently developed into a major environmental challenge influential to the creation of a sustainable society.
The NTT Communications Group makes an effort to avoid affecting ecosystems through business activities such as the construction and dismantling of wireless relay stations within nature reserves. We also engage broadly in awareness activities and dissemination of information through the "eco-goo" portal of Group company, NTT Resonant Inc., on which a special biodiversity website was set up early on.

Laying of Submarine Cables

Ecology in the Ocean

The NTT Communications Group is also actively taking steps to protect the oceanic environment when providing global network services. NTT World Engineering Marine Inc. (NTT-WE Marine), which lays and maintains submarine cables, has designated the prevention of ocean pollution as one of its basic policies. When building submarine network infrastructures, we maintain a high level of awareness as a company that is closely involved with the natural marine environment. Our intention is to fully comply with environment-related laws and regulations, including MARPOL 73/78 (a treaty for preventing marine pollution), and to harmoniously coexist with marine life forms and the fishing industries.

Designing cable routes to protect coral reefs

When designing routes for laying submarine cables in shallow offshore areas, we take care to select cable routes that avoid coral reefs. Where intersecting with coral is unavoidable, we try to lay the cables in naturally occurring trenches in the ocean floor to disturb the coral as little as possible. We also make sure to cooperate with the Ministry of the Environment and other related agencies and government bodies, as well as local fishing industry associations when we plan and lay cables.

Collecting trash from the bottom of the ocean

Before laying or burying submarine cables, we clean the planned ocean seabed route. We collect abandoned fishing nets, rope, and wires during the cleanup operation and take them back to the construction base and properly dispose of them as industrial waste.

Consideration for the marine biotope on cable-laying vessels

On the cable-laying vessel Subaru, the crew take care to clean the anchor chain and rocker, thoroughly removing all mud and attached debris to avoid transporting organic life to other parts of the ocean. This effort helps to protect ocean biotopes.

Considerations During Wireless Station Construction and Dismantling

Caring for Nature Reserves

Wireless station

Wireless station

As of March 31 2011, 10 of our 135 wireless stations for telecommunications and broadcasting networks were in national parks. The NTT Communications Group carefully considers biodiversity requirements in building micro-roads that we need to patrol and maintain these facilities, adhering strictly to the law and our own environmental assessment methods.

Following Guidelines

We produce wireless station construction plans after surveying the distributions of plant, bird, and insect life, and other habitat distribution factors to prevent damage to the biotope. If identifying animals and plants on the World Conservation Union's Red List of endangered species, we contact third-party government bodies and nonprofit organizations to ensure that our construction plans do not affect biodiversity.
In surveying, planning, designing, and working on station sites and roads, we will continue to adhere to our guidelines at each step of our operations to safeguard nesting areas, animal paths, and vegetation.

Awareness Activities Through Provision of Information

Special feature on biodiversity on the "eco-goo" portal

NTT Resonant Inc. took the lead in setting up a special biodiversity site on its Japanese "eco-goo" portal in January 2008. The site uses a test and other features to convey information about biodiversity in a straightforward manner. In April 2009, NTT Resonant joined the Japan Business Initiative for Conservation and Sustainable Use of Biodiversity (JBIB) and worked to enhance the information available through collaboration with the NTT Group and a wide range of corporations in the run-up to the International Year of Biodiversity in 2010.
