Calculate emissions
Matching emission factors
Whether you are making travel offers, managing a fleet of vehicles or creating a financial app: With KlimAPI it is possible to determine the CO2 emissions of your users and support them in making more environmentally conscious decisions.
Expandable with your own factors
You can extend the API with your own factors. For example, you can calculate the emissions of a product based on your own data. You can then optionally combine these with our factors and they will also be displayed on certificates.
Simple operation
Our API is so easy to use that you can integrate it into your system in just a few minutes. You can use the API with any programming language that supports HTTP requests.
