Ecocho.com - You Search, They Grow Trees

Ecocho touts itself as a green search engine that manages to reduce global warming as people use it to search. It is one of many so-called green sites popping up and attaching themselves under the ‘’use me, save the world, be green’ banner. Ecocho isn’t the first green search engine and won’t be the last. But the interesting thing about Ecocho is that for every 1000 searches, Ecocho will plant up to two trees to offset carbon emissions. It’s actually a wrapper for Google and Yahoo so you can choose between the two as your search engine of choice. 70% of revenue will also go to carbon offset credits. Try it out, plant a tree.

“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 balances or "offset" up to a ton of greenhouse gases. We do this by sponsoring two trees via advertising on the site.”

Ecocho has adopted a noble cause. It’s certainly a clever marketing ploy and it’ll make people feel like they’re doing something good for the environment. Moreover, you don’t have to sacrifice your favorite search engine.

What does ‘up to two trees’ mean? Will they actually plant trees and contribute 70% of their revenue to offset carbon emissions? How can they be held accountable?
