If you’re like any average New Yorker, you probably have a very small mailbox. And at the end of the day you probably check that very small mailbox to find it stuffed to the gills with unwanted junk mail. One of the biggest offenders of junk mail is those pesky catalogs that go directly from your mailbox to the recycling bin (hopefully) or to garbage can (more likely).

Well you’re not alone. According to Environmental Defense and its Paper Calculator, 19 billion catalogs are mailed to American consumers each year. And the number of trees the catalog industry uses to produce those 19 billion catalogs is 53 million (no wonder NYC has nearly no trees…) Those catalogs use nearly 3.6 million tons of paper and create enough waste water discharge to fill 53 billion gallons of water, or 81,000 Olympic-sized swimming pools.

By now you might have stopped to ask yourself – in the days of the internet, who uses catalogs anymore? And how can I get them to stop infiltrating my mailbox?

Well, that’s exactly where Catalog Choice (www.catalogchoice.org) comes in. In just eight short months, Catalog Choice has grown to be the largest opt-out service for catalogs, and remains the only free service that lets you decline catalogs you no longer want to receive. To date there are over 910,000 members that have opted out of nearly 12 million catalogs. Its user-friendly website allows you to create an account and send opt-out requests directly to merchants on your behalf.

And are these merchants complying with the opt-out request? Well some – currently about 240 catalog companies – are participating, such as L.L. Bean and Tiffany & Co., and they should be applauded for their efforts to listen to consumers. There are other companies that aren’t yet – and they need to be pressured into complying with these kinds of requests.

If you’re already a member of Catalog Choice, head on over to their blog, and let the folks over there know how it’s working for you. If you’re not yet a member, sign up today and make some more space in your mailbox. Because in the end, it’s not about separating consumers from the goods they want to buy, it’s about increasing market-place efficiencies while reducing unnecessary waste.
