①Global Warming Countermeasure
The anticipated energy usage amount for 2011 shall be undercut by
16%(0.52 bn kWh) and the total emissions of greenhouse gases shall
be limited to 1.52 million tons (CO2 equivalent).
The principal countermeasure
(a) Introduction of mobile base stations with high efficiency.
(b) Introduction of efficient Facilities at Network Centers and Data Centers;
such as inverter type air conditioners, Solar Energy Generation, etc
