VIRTUAL CLIMATE NEUTRALITY
The information and communications technology (ICT) sector
contributes approximately two per cent of the world’s GHG
emissions. However, the use of computers to control and
organize every aspect of our lives and economies gives this
sector a significant influence over the remaining 98 per cent.
Dell, one of the world’s leading manufacturers of computers
and computer-related products, has made the decision to go
climate neutral. But as its own analysis shows [see graphic],
even offsetting every tonne of CO
2
required by the agreed
protocol for carbon neutrality accounts for a relatively small
portion of the emissions associated with its business.
Dell counts within its GHG inventory the direct emissions from
its own factories and facilities worldwide, plus those from
business travel. Together, they amounted to about 470,000
tonnes of CO
2
between 2008 and 2009.
These emissions were, however, just a small fraction of the
emissions which Dell judges to be linked with its own business
and products. About 20 times the company’s own emissions are
estimated to be produced from “upstream” and “downstream”
sources—upstream being emissions frommaking and shipping
components, and downstream being the electricity used in the
running of Dell’s computers and servers worldwide. Emissions
from each of these sources are estimated at five million tonnes
annually (10 million tonnes in total).
Dell is committed to reducing its direct and business travel
emissions as much as possible, while offsetting the rest. Since
around 80 per cent of these emissions are from electricity, this
is where the company will focus its efforts in striving towards
carbon neutrality.
After exhausting the maximum efficiency improvements, Dell
undertakes to account for all of its electricity use through
purchase of renewable energy. As far as possible this is done
through negotiation with the utilities that supply the power
itself—in the United States Dell is able to source 36 per cent
of its power from renewable generation technologies, and 26
per cent worldwide—well above the average availability for
renewable power.
