[The ITU has put out an excellent report called ICTs and Climate Change.
Highly recommended reading and further support to my belief that the ICT
industry can reduce its own emissions to zero but also enable other
traditional carbon heavy sectors of society to reduce their carbon footprint
through "bits and bandwidth for carbon" trading schemes such as free fiber
to the home,  free mobile telephony, and other free eProducts and eServices.

Information and Communication Technologies (ICTs) are undoubtedly part of
the cause of global warming as witnessed, for instance, by the millions of
computer screens that are left switched on overnight in offices around the
world.

But ICTs can also be part of a solution. This Technology Watch briefing
report looks at the potential role that ICTs play at different stages of the
process, from contributing to global warming (section 1), to monitoring it
(2), to mitigating its impact on the most vulnerable parts of the globe (3),
to developing long term solutions, both directly in the ICT sector and in
other sectors like energy, transport, buildings etc (4). The final sections
look at what ITU-T is already doing in this field (5) strategic options (6),
and the campaign for a climate-neutral UN (7).

A major focus of ITU’s work in recent years has been on Next-Generation
Networks (NGN), which are expected by some commentators  to reduce energy
consumption by 40 per cent compared to today’s PSTN 

The telecommunications industry is currently undergoing a major revolution
as it migrates from today’s separate networks (for voice, mobile, data etc)
to a single, unified IP-based next-generation network . The savings will be
achieved in a number of ways:
• A significant decrease in the number of switching centres required. For
instance, BT’s 21st Century Network (21CN) will require only 100-120
metropolitan nodes compared with its current 3’000 locations;
• More tolerant climatic range specifications for  switching locations,
which are raised from 35 degrees (between 5 and 40°C) to 50 degrees (between
-5 and 45°C). As a result, the switching sites can be fresh-air
cooled in most countries rather than requiring special air conditioning.
