Flight Calculator

Flight Calculator is a free Windows Phone application that calculates the carbon dioxide emissions for flights between international airports.

It was developed by RADsite in association with Carbon Footprint Ltd and uses the same airport database and calculation techniques as the free web-based flight calculators but without the inclusion of radiative forcing. Further details about the calculation techniques are available on the Carbon Footprint website.

Support & Custom Development

Due to the demise of the Windows Phone 8.1 and Windows 10 Mobile operating systems, this app is no longer supported or maintained, and we recommend using our free web-based flight calculators instead.
