• With household energy demand increasing over the years, CO2 emissions in 2006 were 1.3 times more than in 1990

• With the spread of FTTH and the increase in CO2 emissions from household communication devices, if With the spread of FTTH and the increase in CO2 emissions from household communication devices, if the number of subscribers reaches 20 million, one-third of all CO2 emissions of the NTT Group will be due to household communication devices
