Let us introduce a new currency into your menu/offer: the Greencent. The Greencent is a reward for 1 kg of non-emitted CO2. Every time your customers order food with a lower CO2 footprint than the average of its category, for example desserts, they get Greencents according to the CO2 footprint of the ordered/purchased meal/product.
How does it work?
