While environmentalist groups have benefited from social networking, keeping the Web working emits a lot of CO2” (Source: Mother Nature Network)

Very interesting story about the contradictions of environmental online campaigning.

From the same article:

In emails alone, the typical officeworker is responsible for 13.6 tons of CO2 or its equivalent per year, a French government agency for energy efficiency, ADEME, calculated last year.

That figure is based on a French company of 100 people who work 220 days a year and each receive 58 mails a day and send 33 per day, with an average mail size of one megabyte.

By comparison, 13.6 tons is more than twice the annual CO2 emissions per capita in France and almost two-thirds of the average annual emissions per capita in the US.”
