In an age of conspicuous consumption, one thing I don’t feel guilty about is buying books. I love books: used, new, antique, paperbacks, hardcovers. You name it, I’ll probably read it, and if I like it, I’ll buy it. I love having a house full of books. And yes, I know: books are made of paper. Paper comes from trees, and I love trees, too. Live ones. So what’s an eco-conscious reader to do when the library and secondhand books can’t help you out?

Eco-Libris thinks it has the answer. Welcome to offsetting…for your books. Here’s how it works: for every new book you buy, you pay Eco-Libris to "balance" your books. They plant 1.3 trees for every balance you pay for. Buy ten books, pay for ten balances (at $1 each) and, within the next year, they will plant 13 trees to replace those cut down to provide the pages and covers of your books (the 13 is to account for trees that may not survive planting.) They send you a bookplate sticker with the Eco-Libris logo to put inside the cover of your offset book. Eco-Libris’ goal is to balance half a million books by 2008.

Eco-Libris has partnered with three non-profit conservation groups for their tree planting, which all happens in developing countries: RIPPLE Africa, The Alliance for International Reforestation, and Sustainable Harvest International which cover planting efforts in five Central American countries and Malawi. All three groups were selected for their collaboration and involvement with the communities in which they are planting.

Their website also has numerous facts and statistics on the publishing industry and its effort to go green which, if you know anything about publishing, is not that great. Eco-Libris provides a call-to-action for publishers to green up their act. One note: this is a for-profit company, if that matters to you. But the cost seems reasonable, and the groups they’re working with are all highly-recommended.
