Four productive scenarios were selected to a comparison based on the agricultural assets and anergetic utilities. A method of work combining standard environmentalimpact indicator (ReCiPe) with energetic and exergetic analysis (CED and CExD) was selected to perform the evaluation. For the situation that all the approaches are evaluated simultaneously, scenario II - ethanol from corn and cogeneration - presents the most balanced Energo and Exergo-environmental perfomaces. Scenario III was deeply influenced by the effects provided by the Brazilian grid. This dependence became unfeasible the alternative. The performance of ethanol production from sugarcane. It is recommended that additional tests of proportioning between agricultural assets may be carried out.  aenvironmental performance  aEthanol production  aLife cycle Assessment  aCana de açúcar  aEtanol  aImpacto ambiental  aEnergy Analysis  aExergy Analysis1 aMATSUURA, M.
