The BEGES is the French legal obligation to publish an emissions report on the ADEME platform. Bilan Carbone® is one of the methods that can be used to produce it, alongside the GHG Protocol or any method that complies with ISO 14064-1. A voluntary Bilan Carbone® can be carried out without it being a BEGES, but not the other way round if you are above the thresholds.
