2. Do I receive a donation receipt/certificate for my offset payment to myclimate?

The contributions to myclimate are tax deductible in Switzerland and Germany. Further information on myclimate is available here.

3. Do I get my money back if the flight is cancelled or I decide to not fly after all?

In such cases, the payment that you have made can be used for your next flight; however, unfortunately we are unable to refund payments once they have been made.

4. What should I do and who should I contact for a refund if I am debited the wrong amount?

If this is the case, please contact myclimate – The Climate Protection Partnership.

5. Am I also able to make a contribution that is higher or lower than the amount calculated by the emissions calculator?

Yes, the emissions calculator is merely there for orientation purposes to determine the scale of the donation. You may determine the actual amount of the offset payment yourself.

7. Besides CO2, are any other emissions included in the calculation of the offset amount?

No, only CO2 emissions are included in the SWISS calculator. This is because in science there is only a clear certainty with regard to the aviation sector about the climate impact of CO2 emissions (see also About the CO2 calculator). However, after calculating the CO2 emissions each customer has the option of varying the payment by clicking on "I'd rather donate a different amount instead".

8. How are tonnes of kerosene converted to CO2 emissions?

The factor is 3.15, i.e. one tonne of kerosene produces 3.15 tonnes of CO2 during combustion.

9. How long does CO2 remain in the atmosphere?

CO2 accounts for the largest percentage of the greenhouse gases produced by mankind. It is also a gas with a long life and remains for up to 100 years in the atmosphere. During this period, it exercises a greenhouse gas effect.
