Compensate reliably with KlimAPI

Well-founded and tested compensation projects

Sustainable and verified projects are remunerated for avoided or reduced CO2 emissions. The compensation is made through the sale of certificates for CO2 offsetting. By purchasing and retiring the verified certificates, you offset your own unavoidable emissions in the past and thus make a contribution to global climate protection.

All information also before purchase

All information on the offset projects we offer is accessible via API before purchase. You can view all the information on the projects and find out more about them. The certificates are automatically retired after purchase and can no longer be resold.

Individual certificates on-demand

An individual certificate is issued for each offset. This certificate contains all the information about the offset and can be passed on by you to your customers. The certificates are generated automatically and can be retrieved by you via our API.

Despite great efforts, it is still almost impossible to live completely emission-free. CO2 offsetting is a sensible alternative for all emissions that have already been caused or are unavoidable. This means that the emissions caused can be saved elsewhere through climate protection projects.
