Global ICT carbon emissions 'unsustainable'

Gartner estimates sector produces as much CO2 as the aviation industry

Robert Jaques, vnunet.com 27 Apr 2007

The global information and communications technology industry accounts for approximately two per cent of global CO2 emissions, new estimates reveal.

Gartner stated that the figure, which is equivalent to that of the aviation industry, is "unsustainable".

The analyst formulated the figure based on carbon estimates of the in-use phase of PCs, servers, cooling, fixed and mobile telephony, local area networks, office telecoms and printers.

Gartner has also included an estimate of the embodied energy in large-volume devices used in design, manufacture and distribution, namely PCs and mobile phones.

It also included all commercial and governmental IT and telecoms infrastructure worldwide, but not consumer electronics other than mobile phones and PCs.

"During the next five years, increasing financial, environmental, legislative and risk-related pressures will force IT organisations to get more environmentally sustainable," said Simon Mingay, research vice president at Gartner.

"When enough buyers start demanding it and we get beyond the superficial, being 'less bad' will no longer be anywhere near acceptable enough.

"That point will be reached in 2007 and 2008 for some geographies, particularly Europe, while other countries and regions will take longer."

Gartner believes that the ICT industry needs to gain a better understanding of the full lifecycle of ICT products and services, and innovate to reduce the environmental impact.

This does not currently happen because of the lack of a commercial or legislative need to do so. However, Gartner anticipates that buyers will ask more detailed questions about lifecycle assessments during the next three years.

"Vendors are being forced to gain a better understanding of the lifecycle due to new legislation and directives in countries and regions worldwide, as well as an increasing interest from clients in lifecycle assessment," said Mingay.

"The areas for innovation to reduce CO2 emissions are in the reduction of the materiality, energy consumption and use of hazardous substances throughout the lifecycle, in addition to increasing the efficiency and effectiveness of recycling and the use of recycled materials."
