The EPA estimates that 650,000 tons of phonebooks are delivered annually to 100 million households in the United States. Producing those 650,000 tons of phone books uses 11.6 billion gallons of water and sends 1,650,880 tons of Carbon Dioxide into the air (CO2 is a greenhouse gas and contributes to global warming). The EPA estimates that only 18% of the phone books that are discarded in the United States each year are recycled. That leaves 533,000 tons to take up 1,758,900 cubic yards of landfill space.
If you are among the 54% of Americans that use the internet or a cell phone to search for phone numbers, you can opt out of receiving your annual phone book (or books).
I think this is the only responsible thing to do — if you do not want a phone book next time around, then please opt out at this web page:
