Abstract: A customized LCA-based tool (RenovaCalc) was developed by a multidisciplinary team (specialists in LCA, LUC, GIS), to perform calculations and support the RenovaBio certification scheme. The structure of RenovaCalc is based on the attributional LCA approach of \ "well to wheels \" using energy allocation criteria for the calculation of the Sucarcane and Maize Alcohol, Biodiesel, Biomethane and Biojet grades. Background data (input carbon profiles, such as fertilizers, electricity, etc.) comes from Ecoinvent 3.1 and the IPCC emission and characterization factors
