Green Browsing with ECO2
ECO2 is a concept for a desktop software, that automatically measures your computing habits, e.g. how many servers you connect to, which online worlds you explore, or how many print-outs you make. It then calculates your electronic CO2 footprint.


Your footprint is visualised directly on your desktop as a slowly greying and finally decaying landscape. Linked to a donation system, you can offset your electronic CO2 footprint and turn your desktop back into a bright, clean environment, while simultaneously trees in the real world are planted.

Desktop Widget / Air Application

CO2-calculator
The desktop application can be minimised to widget form; or extended into a full CO2-calculator to offset all your household's CO2-emissions.






ECO2 was developed as a self-initiated project. It won first place at the "IID Green Day", a competition in Tokyo around "green ideas". Our presentation was based on the idea that virtual avatars produce very real CO2-emissions, too.
