                         (Saccharum officinarum) based ethanol is critical to assess the 
                         degree of carbon (C) neutrality of biofuels. Few studies have 
                         considered the GHG emissions from sugarcane cultivation while 
                         taking direct land use change (dLUC) into account. This study was 
                         conducted to enhance scientific understanding of the GHG balance 
                         related to sugarcane cultivation while considering dynamics of all 
                         C pools (biomass and soil) upon conversion of diverse land uses 
                         into sugarcane during 20062011 in south-central Brazil. Based on a 
                         comprehensive evaluation of survey data and given that the 
                         sugarcane cultivation and dLUC can be credibly assessed by using 
                         remote sensing satellite images, estimations of GHG emissions were 
                         performed using the IPCC methodologies and expressed in terms of 
                         Tg CO2eq (Teragram=1012 g=1 million Mg) considering a 20-year time 
                         horizon. The overall accumulated GHG balance was 217.1 Tg CO2eq by 
                         2030, with an emission of 481.6 Tg CO2eq from sugarcane 
                         cultivation being offset by a biomass C sink of \−274.5 Tg 
                         CO2eq. Soils had an almost neutral C budget with a slight emission 
                         of 10.0 Tg CO2eq by 2030. Nevertheless, the ethanol C offset by 
                         displacing fossil fuels could readily payback that C deficit and 
                         ensures the environmental benefits of sugarcane ethanol. Our 
                         results show an increase of C reservoirs (biomass and soil) 
                         through conversion of arable and pastoral lands into sugarcane, 
                         and a decrease of C reservoirs when citrus, plantation forest and 
                         natural forest are converted to sugarcane. Here we support that 
                         the impact of dLUC on biomass and soil C pools must be considered 
                         while expanding sugarcane plantation as an important mechanism for 
                         GHG abatement beyond the avoided emissions through use of 
                         sugarcane ethanol.",
