Very functional yet easy to use, Dopplr has been my favourite travel manager for almost a year now. Since April, they even calculate the carbon footprint of your travels, a handy way to take responsible decisions when planning your trips.
Dopplr is so well done, that in the end, the only thing you want to do is travel more. You don’t want to see the list of your future trips empty. Luckily, the carbon calculator will send you back to reality. The more miles you travel, the more carbon you’re producing. Calculations are provided by AMEE.cc (Avoiding Mass Extinctions Engine in Climate Change) using an API. The calculation is very accurate, since Dopplr allows you to precise which mode of transport you’re using for a particular trip. You’ll quickly notice that flying has much more impact on your carbon profile than using the train. I produced 660 kg of CO2 so far for this year. I believe that my carbon emissions due to transport have been greatly reduced thanks to Dopplr.
