abstract = "Inventorying greenhouse gas (GHG) balance associated to sugarcane
(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.",
