Bunga is a Firefox-plugin that you download and install in your browser. As soon as you`ve done that, you can visit any webpage, select the name of a company and find its sustainability ranking with a short description of its activities.
The Bunga extension allows you to close the gap between the company and the name or synonym in any web accessible context.
Think about that: you can go to Coca-Cola`s own website for instance, click on their name and find out how sustainable they really are! How about that for transparency?
The Bunga addon is cross-platform and it works on Mac OS X, Windows and Linux.
