# Proof of concept

A Norwegian company [CHOOOSE](https://chooose.today/) offers a digital API that various aviation, travelling, hospitality, and other companies can introduce on their checkout page if they want to offset the carbon footprint of their service or product. The company then uses donated funds to implement nature-based solutions, carbon removal, Sustainable Aviation Fuel and other measures to offset the climate impact of the service/product. CHOOOSE serve clients such as Heathrow, Norwegian, WizzAir, Santander and more, acknowledging the need for climate offsetting APIs in direct-to-consumer platforms. The example of CHOOOSE illustrates how, if given a choice, customers are likely to offset their footprint. Meanwhile, the users of DeFi platforms are not presented with an option to act climate positively.
