Product description
More and more travellers want to take the climate impact of their trips into account and contribute to climate action accordingly. At the same time, travel service providers are looking for practical solutions to integrate climate action into their offerings in a simple and flexible way. atmosfair offers flexible models that can be easily integrated into existing booking processes. During the booking process, travellers can make a voluntary contribution to climate action, supporting high-quality climate action projects run by atmosfair. Contributions are settled either directly through atmosfair via API or by the travel service providers on a trust basis.
Depending on the specific application, two solutions are available. In both cases, travellers receive a certificate from atmosfair:
CO₂ offsetting based on calculated emissions
atmosfair calculates the emissions generated by a journey based on the travel details provided. Travellers can then offset these emissions directly through atmosfair’s climate action projects. atmosfair is currently the only provider that can offer its customers ‘genuine CO₂ offsetting’ in accordance with the Paris Agreement on climate change, without double counting. See the test by Stiftung Warentest 2025.
Climate action packages as a flat-rate additional service
Alternatively, you can offer your customers flat-rate contributions through our climate action packages. In this case, travel emissions are not calculated individually. Instead, customers can choose a climate action package of a suitable size and make a flat-rate contribution to support climate action projects. These packages are particularly suitable for booking processes in which an individual calculation of emissions is either not desired or technically impossible.
- Calculation and offsetting of emissions based on travel data (optional), or climate action packages as a flat-rate solution
- Easy integration of climate action offers into existing booking processes via API
- Implementation support from the atmosfair IT team
- Fiduciary handling of climate action contributions or direct processing through atmosfair, with no additional workload for your accounts department

Benefits for your business
- Offer sought-after climate action options as an additional service: Expand your offering to include a voluntary climate action option, giving your customers the opportunity to take responsibility for the climate impact of their journeys.

- Showcase your own commitment to sustainability: Integrating climate action options highlights your commitment to sustainable travel and complements your existing sustainability strategies.
Why atmosfair?
Genuine carbon offsetting without double counting
For more than 20 years, atmosfair has been working with companies in the travel industry, helping travellers contribute to climate action. These contributions support selected atmosfair climate action projects that not only reduce greenhouse gas emissions but also promote sustainable development at the local level. atmosfair is currently the only provider that can offer customers genuine CO₂ offsetting in accordance with the Paris Agreement, without double counting. See the test by Stiftung Warentest 2025.
Non-profit and independent
As a non-profit climate action organisation, its focus is on effective climate action, transparency and the careful use of funds.
Standards and certifications
Emissions are calculated using atmosfair’s scientific methodology (VDR standard), drawing on many years of experience in mobility and travel. The climate action projects supported are registered with the United Nations and Gold Standard, or with CSI or Isometric in the case of carbon removals. They are audited annually by independent third parties. Further information on the climate action projects and quality standards can be found on our project pages.
Pricing
There are no costs for travel service providers to integrate or use the atmosfair interface when offering CO₂ offsetting or climate action packages.
