Our on-line calculator, below, will work out your share of emissions created by your flight, based on the length of the journey and your cabin class. Emissions are estimated by dividing the total fuel used on a journey by the number of passengers. You can enter a maximum of six flights under one calculation. Learn more about our calculation method.
In addition to calculating individual trips, you can also make a one-off contribution, using either cash or your Asia Miles.
Your cash donation, in the range of HK$10 to HK$999,999, should be rounded off to the nearest dollar.
For Asia Miles, the redemption range is 100 to 999,999 miles.
Learn more about the flights that can be offset for different contribution amounts.
I would like to make the following one-off contribution to the FLY greener Project.
