turetzsr Posted July 18, 2012 Share Posted July 18, 2012 ...Interesting article at the UK Guardian Green Blog: "What's the carbon footprint of ... email?" ...Excerpts: <snip> Very roughly speaking (remember that all complex carbon footprints are really best guesses), a typical year of incoming mail for a business user â€“ including sending, filtering and reading â€“ creates a carbon footprint of around 135kg. That's over 1% of of a relatively green 10-tonne lifestyle and equivalent to driving 200 miles in an average car. According to research by McAfee, a remarkable 78% of all incoming emails are spam. Around 62 trillion spam messages are sent every year, requiring the use of 33bn kilowatt hours (KWh) of electricity and causing around 20 million tonnes of CO2e per year. McAfee estimated that around 80% of this electricity is consumed by the reading and deleting of spam and the searching through spam folders to dig out genuine emails that ended up there by accident. spam filters themselves account for 16%. The actual generation and sending of the spam is a very small proportion of the footprint. Link to comment Share on other sites More sharing options...
