Abstract book... Poznan: Poznan University of Technologyc2019  ap. 286  aAbstract: Land Use Change (LUC) has great relevance for Brazilian overall CO2 emissions. Considering its relationship to agricultural production, especially for biofuels and biomaterials production, it becomes paramount to understand and replicate improvements on the methodologies to measure LUC in the ethanol chain. The objective of this work is to reduce uncertainties and to ensure traceability in the calculation of the variation of carbon stock in the soil and Biomass, during the ethanol production process in Brazil aiming at a complete LCA of the product. In this sense, Braskem, the world\'s largest producer of biopolymers, Atvos the largest supplier of ethanol, Embrapa (Brazilian Agricultural Research Company) and Quantis (Swiss sustainability consultancy) joined together to experiment a method of estimating LUC emissions, which will feedback the process to help to develop a LUC accounting guidance.  aBioethanol  aGeographic information systems  aLife cycle assessment  aBiocombustível  aCadeia Produtiva  aEtanol1 aALCANTARA, M.
