Only partly: Bilan Carbone® mainly draws on ADEME's Base Empreinte, a free public database, and monetary ratios (tCO2e per euro spent) for scope 3 purchases, quicker to use but less precise. LCA uses physical data (kg of material, kWh actually consumed) and databases such as Ecoinvent or GaBi, covering the 16 indicators rather than climate alone. An LCA can also enrich the next footprint assessment by replacing monetary ratios with physical data.
