How It Works
Let Your Customers Start Their Vacation with a Clear Conscience
Automatically Calculate the Trip's Footprint
With KlimAPI, you can automatically calculate the CO2 footprint of your trips. Simply pass your customers' anonymized travel information to our interface, and we will calculate the trip's carbon footprint.
Provide the Option for Compensation
Give your customers the opportunity to compensate for their trip's CO2 emissions. You can integrate compensation directly into your booking process or allow customers to pay for it afterward.
Individual Certificates and Climate Contributions
We provide individual certificates for each trip. This allows you to show your customers how much CO2 they have compensated and their contribution to climate protection.
