Spammers scourge to Inbox and Environment, so study finds

by Michael Smith (Veshengro)

There are plenty of reasons to hate spammers. Add this to the list: They're environmentally unfriendly.

A report being released on April 16, 2009 by ICT security company McAfee Inc. finds that spammers are a scourge to your inbox and the environment, generating an astounding 62 trillion junk e-mails in 2008 that wasted enough electricity to power 2.4 million U.S. homes for a year. That is a lot of wasted energy for sure

The "Carbon Footprint of E-mail Spam Report" by McAfee estimated the computational power needed to process spam; from criminals tapping their armies of infected PCs to send it, Internet providers transmitting it, and end users viewing and deleting it.

The report concluded that the electricity needed to process a single spam message results in 0.3 grams of carbon dioxide being released into the atmosphere - the equivalent of driving 3 feet in a car.

"While the spam that arrives in any individual's inbox may create just a small puff of CO2, the puff multiplied by millions of users worldwide adds up," wrote McAfee. McAfee relied on data generated by energy and environmental consultancy ICF International Inc. to reach its greenhouse gas estimates.

The report found that almost 80 percent of spam's greenhouse emissions come from the energy that PCs consume while users are viewing, deleting, or sifting through spam looking for legitimate messages.

McAfee says it takes users about three seconds to view and delete a spam message. Although most spam doesn't get through because of sophisticated spam filters, and chance would be a fine thing, people spend a lot of time - 100 billion user-hours per year - dealing with the messages that do land in inboxes, McAfee estimates.

The findings are significant because most e-mail is spam. The latest figures from Microsoft Corp. show that unwanted messages account for 97 percent of all e-mail and unfortunately some of it is generated by Microsoft themselves and others simply is not filtered correctly.

There is one area, however, where spammers might claim the environmental high ground.

Spammers need to limit the size of their attachments to evade detection, so their messages wind up consuming much less energy than legitimate e-mail. McAfee's report estimates that the emissions from processing a single piece of legitimate e-mail are around 4 grams of carbon dioxide - 13 times spam's emissions - because users linger on them longer and attach bigger files.

But, when considering the environmental footprint of legitimate emails with all those attachments, we might also consider the cost to the environment would that email be sent as a letter proper with the material that is digitally attached being enclosed in an envelope. How much do we think that would be?

As far as most of us are concerned, even though we must consider the environmental impact of spam emails, is the impact spam emails have on us when trying to deal with out emails.

I personally have a number of email accounts and the ones, for instance, that are of the former “”, now part of the Tiscali group, are getting nothing but spam, basically, and apparently Tiscali is incapable of doing anything about it – unless you pay for it. It is, as far as I am concerned, annoying in the extreme as I am also not really interested in the tablets they want to sell me and other products.
