Ecocho saves trees as you search

You search and they grow trees. That's Ecocho's philosophy on their status as the "first green search engine".

Their website says, "Ecocho is a new search engine trying to make a difference for climate change. For every 1000 searches users make on Ecocho we'll counter balance or "offset" a ton of greenhouse gases. We do this by sponsoring two trees via advertising on the site."

Ecocho uses Yahoo search technology to allow users to search for any topic they could think of. For every 1,000 searches on Ecocho, they can purchase enough credits to remove 1 ton of CO2 from the atmosphere.

"We know that much more must be done long term than just planting trees," they say. "But if we can make the way people search the Internet not only help the environment but also take no significant initial adjustment on their part, Ecocho can gently increase participation whilst sowing the seed of ecological thinking for greater change to follow. Ecocho could start the ball rolling."
