Offset your carbon emissions

If you’re looking to offset your flights, you can use our online calculator to work out your share of the carbon emissions. This number is calculated by dividing the total fuel used on a journey by the number of passengers. To learn more about our calculation method, please visit on our Fly Greener FAQs page.

You can also choose to make a one-off contribution, using either cash or your Asia Miles. To do so, simply select ‘Lump sum contribution’ below.
