Research and proposals for reducing environmental impact through ICT: Participation in government projects
Despite higher electricity consumption due to the spread of ICT devices, ICT services can reduce the CO2 emissions of society as a whole by boosting the efficiency of production processes, reducing demand for transportation and delivery, and reducing the need for production of physical media such as books, CDs, and DVDs by enabling the download or streaming of content. Calculations performed by NTT indicate that the use of ICT services in Japan during fiscal 2008 resulted in energy savings equivalent to 2.5% of the country's energy consumption.
With the enactment of the NTT Group Vision for Environmental Contribution in fiscal 2007, we declared our commitment to protecting the global environment by further expanding our business operations to provide ICT services. Based on this policy, NTT laboratories evaluate the environmental impact reduction effects of leading R&D products that have been adopted by Group companies, and share their findings with those companies as part of NTT Group environmental management. NTT Information Sharing Laboratory Group is also investigating how ICT can effect mid-to-long term reductions in the environmental impacts.

CO2 emissions fell by 120,000 tons annually by connecting different locations with videoconferencing systems
In March 2007, NTT BizLink, a member of NTT Communications Group, measured the environmental impacts of using its Multipoint Video Conferencing Services that can simultaneously connect multiple locations, and found that use of the technology is resulting in a CO2 emissions reduction of up to 120,000 tons annually. These results were also posted in the Assessment of ICT-Driven Environmental Impact Reduction announced in April 2008 by the Ministry of Internal Affairs and Communications.

Reduces data center power consumption with Green Data Center services
To fulfill its responsibility as Japan's largest data center operator in terms of floor space, NTT DATA launched its Green Data Center service in January 2008 to reduce data center power consumption, promote CO2 emissions reductions, reduce environmental impact, and increase ICT efficiency. Comprised of IDC, building and design, housing services, and from October 2008, a shared IT platform service, the Green Data Center service is promoting next generation corporate ICT platform strategies and supporting the creation of new corporate value from the perspective of both the environment and ICT.

CO2 emissions reduced by 81% compared with use of onsite monitoring personnel
NTT Communications provides an OCN for Monitoring service that uses its OCN network and netcams to enable real-time remote monitoring of shops, works sites, and factories. This service can reduce CO2 emissions by 81% compared with the use of onsite security and monitoring personnel.
