Organic. Sustainable. Recycled. It seems we're all looking for ways to add a little "green" to our lives! Whether it's researching alternative energy, finding the local recycling facility, or looking for a place to swap healthy recipes… there are tons of websites dedicated to providing news, tips, resources, and communities to help us do our part for Mother Earth.

In honor of the 40th Anniversary of Earth Day, we've assembled a list of the 40 best websites for advertising to green consumers. Fingers crossed that the planet and all of us are around for the 80th Anniversary!

These selections were ranked based our editorial review, monthly US visitors (estimated by Compete), and Google page rank (a key factor in determining ranking in search results… the higher the better).

So many choices so little time? Here's another great option – advertising networks like Natural Path Media and SustainLane Green Ad Network specialize in advertising across sites with an environmental focus.

Keep in mind that for many people, "going green" is a way of life, not a single act or purchase. Invest the time to craft the right message for this progressive audience… and you'll be taking your "sustainable" sales growth all the way to the bank (in your hybrid car of course)!
