As if you need another reason to hate spam…
A new study reports that about 62 trillion spam messages are sent each year, giving off the same amount of CO2 as driving around the earth 1.6 million times. To break that down, one spam releases 0.3 grams of carbon dioxide, which is the equivalent of driving three feet, according to The Wall Street Journal. (Thanks to Ryan Avent at Portfolio.com for the link.)
Spam accounts for one-third of all business and personal messages. Yowza. I believe it. I just added a spam counter to the right sidebar here, and look how many spam comments I’ve had to go through! Boy they are just awful, too. Personally polluting, time polluting, and environmentally polluting.
How To Minimize Spam
1. Filter your spam. Apparently “spam filtering saves 135 terrawatt hours of electricity a year, the equivalent of taking 13 million cars off the road,” according to The Wall Street Journal. It is likely your email system has a decent spam filter. Check your email preferences and make sure the spam filter is on and working at maximum capacity. If you have your own domain or ISP, you can probably use a more robust filtering system through your service provider – just ask them.
2. Use a disposable email address for things you want to sign up for but will never need to use again. About “80% of the greenhouse gases created by spam actually comes from the process of deleting it, or by searching around for legitimate emails trapped in spam filters.” I use an email address specifically for such purposes – my “donotspam” email address!
3. Uncheck the check boxes. When you sign up for membership to a website, listserv, or campaign, they will often have a check box – which is usually pre-checked – asking if you want to receive ads and other emails. UNCHECK the check boxes!
4. Avoid publishing your email address anywhere on the web, unless it is disguised. There are several ways to do this. Here, I’ve set up a “Contact” page so that the sender never knows my email. Kills me to do that, but I learned the hard way with my last blog! You can also put up a jpg or png image file of your email address, so that “spiders” and “trawlers” can’t automatically find your email and stick it in a database (they can’t read images). Or you can do the simple “joe at gmail dot com” technique. Any of the three work fairly well.
5. Google your email address. If it comes up on any site, do everything you can to remove it! Ask the administrator – they’ll probably do it without much fuss.
6. When posting to newsgroups and listservs, be careful not to post your email address if you can help it. Often there is a preference to remove your email address. If you can’t remove it, use a disposable email address (see #2).
7. When forwarding emails from someone else – and particularly a group of people – make sure you remove all the old email addresses from the email. You never know where that email will end up – you could be handing a spammer 50 of your friends’ personal email addresses!
8. Ignore “delivery failures” of messages you did not send - these are probably sent by a worm, Trojan, or spammer. Don’t reply! (Worms are programs that can send bulk emails – they often live on your unsuspecting friends or family’s computers as a virus.)
9. Run virus scans regularly on your computer. Worm viruses can actually send spam to everyone in your address book. Icky. PCs are much more vulnerable to worms than Macs. Also make sure your anti-virus software is up to date and from a reputable company.
10. Don’t reply to spam. Even if you reply in order to request removing your email address from the mailing list, you are actually confirming that your email address is valid and the spam has been successfully delivered. Then your email address may be sold to additional spammers, being more valuable now that it has been confirmed. Even opening the email may trigger this confirmation, so try not to open spam if you can help it.
And finally, never respond to emails that ask you to validate or confirm any of your account details of your bank, credit card, Paypal, or others. If you are not sure if a request for personal information is legitimate, contact the company directly. Don’t click on any links in the email, as they may be fake links which simply validate that you received the message and you can now be put on more spam lists.
All in all, spam is a small portion of the total climate and energy impact of humans. But as we all are aware, every little bit helps. And since spam is such a nuisance anyway, why not take a few extra precautions to rid society of spam?
