As the 2014 UN climate summit takes place in New York, this transportation-specific carbon emissions calculator is extremely relevant. The mobile app is developed for both Android and iOS by the International Civil Aviation Organization. It is used when booking flights to determine the environmental impact your ticket has. The smartphone application estimates what portion of CO2 your air travel represents.
