Controlled trade and sustainable manufacture have scarcely played a role in the activities of online dealers thus far. Things are different with Fairmondo. The online marketplace promotes fair and sustainable products and, as a cooperative, is setting a good example: more than 18,700 private individuals and commercial dealers jointly ensure transparency and openness in the company, and sell and buy around three million products. As an open source platform, its goal is to serve the common good rather than shareholders and to foster conscious consumption. For every transaction carried out a "fair percent" is donated to a nonprofit organisation. Hence it is easy for users to discover - and do - good deeds.
