  • A plan is the software itself: you add a year of bills, it works out your footprint in tCO2eTonnes of CO2e, the unit a carbon footprint is given in. One tonne is 1,000 kg of greenhouse gases, counted as if they were all CO2.More in the glossary and writes the reports. Every plan makes the Plan de réduction carbone (CRP)Un document public présentant vos émissions des scopes 1 et 2 et certaines émissions du scope 3, et vous engageant à atteindre zéro émission nette.
