[via a welsh view] Ecocho: A new search engine trying to make a difference for climate change. For every 1000 searches users make on Ecocho we’ll counter balances or ‘offset’ up to a ton of greenhouse gases. They do this by sponsoring two trees via advertising on the site.

It uses Yahoo and Google results and for every 1,000 searches made on the site they will donate 2 trees. So far they’ve planted 3,241 trees and offset 1.6KG of CO2.
