The Kyoto Protocol went into effect in February 2005. The Kyoto Protocol mandates an average 5.2% reduction in CO2 and other greenhouse-gas emissions from 1990 levels by industrialized countries between 2008 and 2012. Under the Protocol, Japan is obliged to reduce emissions by 6%. In Japan, however, emissions of greenhouse gases are on the rise, and an increasingly active commitment to preventing global warming is expected.
Amidst these circumstances, the NTT Group is undertaking a number of commitments, with the belief that the increased use of IT can help greatly to reduce CO2 emissions. According to actual calculations made by NTT, online eCommerce systems, teleconferencing systems, supply-chain management (SCM) systems*, and other systems that facilitate the movement of people and goods via IT can reduce Japan's total energy consumption by 3.9% by the year 2010. This study was undertaken in partnership with leaders in the field gathered together for the Conference for Research on the Evolution of the Ubiquitous Networked Society and the Environment, by the Ministry of Internal Affairs and Communications.
B FLET'S TV Relay System Reduces CO2 by 70%
B FLET'S is a well known type of broadband services. In order to evaluate the benefit of reduction of environmental load from this service, NTT West's Hiroshima branch have undertaken a lifecycle assessment for a TV relay system using B FLET'S, which is offered to RCC BROADCASTING CO.,LTD. The results showed that a TV relay system using B FLET'S*1or FLET'S Spot *2 could reduce total CO2 emissions by 70% from those of a conventional microwave TV relay system. This is equivalent to a reduction of about 3.2 t-CO2/year.
Ordinary TV relay systems use microwave transmission system to broadcast video and sound from a filming location, via relay stations. On the other hand, TV relay systems using B FLET'S convert video and sound shot at a filming site into transmittable signals. They enable relaying to be performed very simply, requiring only equipment to convert the video and sound into digital data, and equipment capable of making a B FLET'S or FLET'S Spot connection.

Ultra High-definition Digital Cinema Delivery System Reduces Use of Materials and Energy
 Ultra High-definition Digital Cinema Delivery System
With current cinematographic film, it is impossible to avoid deterioration during the production process, and during repeated screenings in the theater. Digital cinemas overcome the problem of video deterioration by digitizing the video data.
NTT Network Innovation Laboratories has developed an ultra high-definition digital-cinema delivery system using 8 megapixel (4,000X2,000)-class video technology. Ultra high-definition digital cinema is fully capable of reproducing the quality of 35-mm cinematographic film. It has been adopted as the highest standard in digital cinema, stipulated by the Digital Cinema Initiatives (DCI) of Hollywood.
Using this system makes it possible to greatly reduce the amount of film required to produce and screen a movie. At the same time, it is an environmentally aware cinema-delivery system that makes it possible to reduce the energy required to move people and goods to the theaters.
