In an era of smart phone it is easier and more efficient way to make people aware of their carbon emissions. CarbonDiem, an app developed by Andreas Zachariah, measures the carbon footprint of users based on commuting habits. It uses an algorithm that calculates your carbon footprint based on the mode of transportation you chose. The data is displayed in the form of graphs in terms of carbon, modes of transport, and distance. An interesting finding from CarbonDiem is that transportation emissions and travel infrastructure density are typically high in developed countries.
