Calculate Emissions
Suitable Emission Factors
Whether you offer travel, manage a vehicle fleet, or develop a finance app: With KlimAPI, you can determine your users' CO2 emissions and help them make more environmentally conscious decisions.
Extendable with Custom Factors
You can extend the API with your own factors. For example, you can calculate a product's emissions based on your own data. These can then optionally be combined with our factors and will also be displayed on certificates.
Simplest Operation
Our API is so easy to use that you can integrate it into your system in minutes. You can use the API with any programming language that supports HTTP requests.
