The carbon footprint feature is divided into a basic and advanced carbon footprint model. In short, the basic model consists of automatic calculations for taxi trips, mileages and per diems. This feature may be activated with little to no configuration. There is also the option to activate the advanced carbon footprint feature, where you may make CO₂ calculations on all expenses, mileages and per diems. This feature will need more configuration, but you can ensure that your CO₂ tracking aligns with your company's ESG reporting.
