CarbonDiem shows travellers their carbon emissions in real time on their Smartphone. The app works in the background 24/7 detecting a user’s mode of transport and route, this information is then used to calculate the carbon emissions from the journey. Users can then see their emissions, and those of their friends, on a bright and simple interface, making it easy to understand the environmental impact of their travel and helping them make smart travel choices.

CarbonDiem was an AppMyCity! finalist at the NewCities Summit 2012 in Paris, France and is now part of our Global Urban Innovators Alumni.   @CarbonDiem
