The Ecological Impact of Spam 176
krou writes "A new study entitled 'The Carbon Footprint of Spam' (PDF) published by ICF International and commissioned by McAfee claims that spam uses around 33 billion kilowatt hours of energy annually, which is approximately enough to power 2.4 million US homes (or roughly 3.1 million cars) for a year. They calculated that the average CO2 emission for a spam email is around 0.3 grams. Interestingly, the majority of energy usage (around 80%) comes from users viewing and deleting spam, and searching for legitimate emails within spam filters. They also claim that 'An individual company can find that one fifth of the energy budget of its email system is wasted on spam.' One of the report's authors, Richi Jennings, writes on his blog that 'spam filtering actually saves an incredible amount of energy.' He continues, 'Imagine if every inbox were protected by a state-of-the-art spam filter. We could save about 75% of the spam energy used today — 25 TWh per year; that's like taking 2.3 million cars off the road.""

My God! That is fantastic! If only we had the option to purchase a "state-of-the-art spam filter!" Wait, I know! McAfee, the people who sponsored and paid for this research, have SpamKiller [mcafee.com]! It's perfect.
... that would have to be some pretty impressive and efficient Bayesian filtering with an amazing database technology to drop below viewing and deleting e-mails.
Although I can't access the PDF (download hangs), could you please direct me to the part of the 'research' where you analyze the amount of energy used to perform complex computational functions on tokens from e-mails against a database. And prove that this is less than the energy wasted flipping though e-mails and deleting spam? I mean, the network usage is going to be the same so
And maybe you could factor in the cost and subscription to said state-of-the-art spam filter?
What? You didn't include that analysis in your research? It sounds like a very crucial part of convincing me to acquire a state-of-the-art spam filter. You missed that part?
You don't say.
What, a spam filter, like the one sold by McAfee? (Score:2, Insightful)
Well, of course it uses energy.
But you could also argue the fact that nearly as much energy was wasted conducting the survey and then it getting posted to /., then having all those people read it.
Sounds like an MS study on linux to me...

Or far less than one container ship.
I know, that's for particulate and SO2 emissions, not CO2.
But still, kind of puts things in perspective, huh? Imagine if we bought fewer consumer goods from 8000 miles away... and how much less energy would be consumed. It could dwarf the savings from spam filtering -- not that this makes spam filtering any less of a good idea.
On a side note, I'd like to propose a new standard unit for the metrically challenged.
Superfreighter -- a unit for large amounts of particulate and SO2 pollution. Approximately equal to 50 million cars.

There must be massive amounts of energy and bandwidth wasted just punting the stuff around the world, nevermind viewing it once it reaches its destination. The earlier spam is caught and filtered the better.. it's such a waste. We get our mail filtered by MessageLabs before it ever hits our own servers, I reckon we probably get our money's worth quite easily via the bandwidth we're saving. It would still be nice just to wipe it out at the source of course.

The majority of the energy is spent reading the spam and searching spam folders for legit mail, right?
So where is that energy coming from / going? Perhaps you're counting the energy of running my PC while I'm doing those things? But what's your "0 energy" baseline? Are you assuming that 30 secnods of me searching my email = 30 additional seconds before my computer gets to swtich to power-save mode? Because that's not always true -- it often means 30 seconds less of me playing some game before my ride shows up, and the computer goes to sleep at the same time it would've otherwise.
Maybe its the energy the server spends reading the email from disk that's significant. That might be a vaild concern...

Good ol' carbon footprint. Best racket ever invented. You can sell a solution to a problem that doesn't exist and to solve the problem (after others have paid you (immense amounts of cash) to do so for them) is to do nothing!
Got a technology that would be inconvenient for your pocketbook? Say it has a large carbon footprint.
Got a company that isn't paying you money yet? Pass cap and trade legislation and make them pay you.
And just by coincidence you have the only [product] that meets carbon footprint standards...

Don't let anti-corporate hysteria blind you from looking objectively at this problem. Well, if spam did not exist I would not need a state of the art spam filter. That would be 2U less rack space and about 200W less power I would need to use in my data center. Really, just multiply all the instances of dedicated spam filters, proprietary or otherwise, and it's pretty easy to come up with a number. Plus, I'll bet 5% of Google's resources are dedicated to spam blocking and at least 5% of any ISP's resources are dedicated to transporting it. That's a big number.
Of course, McAfee would not exist either. Lots of people would be unemployed, and maybe they could find a cure for world hunger or something else useful instead.

Um, yeah. No. Stopping spam at the recipient end, after it's already been generated at someone else's compromised machine and gone through all those tubes and things, isn't going to save much in the way of actual energy. I suspect this number is wildly optimistic, IE, made up.
I mean, I hate spam as much as the next computer user, maybe even more, as sysadmins see more of the larger impact. There is some amount of vicarious satisfaction in focusing the Fury of the Greens at spam. But if you're really sincere about saving energy, and not just indulging in hyperbole, you want to stop it at the sending end.
