We've been working for the better part of two years on a new online platform called Ekofy. The service gives the opportunity to rate any company based on their ecological and ethical footprint. The platform already boasts a large database of companies, which is constantly updated according to the requests of our users.
The idea came from our belief that the market economy is the most powerful weapon to prevent an ecological crisis. If everyone were to vote with their wallets and buy more sustainable products, all companies have to compete to be more sustainable.
The beta version of Ekofy was just released and we would greatly appreciate your ideas and opinions about it! You can sign up through http://signup.ekofy.com
