FAQs on CO2 offsetting

1. Who should I contact if there are technical problems during the transaction?

In such cases, please contact:
myclimate – The Climate Protection Partnership
Pfingstweidstrasse 10
Zurich, Switzerland
Tel. +41 44 500 43 50

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 at

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.

6. Why do I have to pay an additional fee of EUR 3.00 for contributions that are below EUR 20.00?

In order to be able to cover the administrative costs and charges, it is necessary to charge an additional fee for smaller contributions. The attempt to cover these costs with the higher contributions would constitute a risk for myclimate as a non-profit organization, as it would no longer be possible to entirely cover all the costs if the smaller contributions became very common and exceeded a certain threshold.

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

No, only CO2 emissions are included in the Lufthansa calculator. This is because science only offers absolutely clear answers in respect of the impact on the climate of CO2 emissions (see also The CO2 emissions calculator ). However, after calculating the CO2 emissions each customer has the option of varying the payment by clicking on "Contribute another amount".

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.
