A study into spam has blamed it for the production of more than 33bn kilowatt-hours of energy every year, enough to power more than 2.4m homes.

Did you know, the Carbon Footprint of e-mail Spam report estimated that 62 trillion spam emails are sent globally every year.

This amounts to emissions of more than 17 million tons of CO2, the research by climate consultants ICF International and anti-virus firm McAfee found.

Searching for legitimate e-mails and deleting spam used some 80% of energy.

The study found that the average business user generates 131kg of CO2 every year, of which 22% is related to spam.

Unwanted traffic

ICF say that spam filtering would reduce unwanted spam by 75%, the equivalent to taking 2.3 million cars off the road.

However, the ICF goes on to say that while spam filtering is effective in reducing energy waste, fighting it at the source is far better.

The Spam Report follows only a few days after Symantec's bi-annual Internet Security Threat report, which found that spam had increased by 192%, with bot networks responsible for approximately 90% of all spam e-mail.

The vast majority of spam is sent via botnets.
