In addition to CO2, aviation affects the climate through other emissions and atmospheric processes, such as the formation of ozone and contrail cirrus. These non-CO2 effects account for about 2/3 of aviation's total climate impact but can vary widely from flight to flight. Although scientists have complex models to determine the climate impact of individual flights, there was no simple tool for the public to estimate this relatively accurately and quickly.
In this project a user-friendly Excel application has been developed that provides an estimation of the climate impact of a single flight that is much more detailed than a simple constant factor. Users simply need to enter the origin and destination of the flight and the aircraft size category.
