Abstract:
Purpose of this work was to evaluate the greenhouses (GHG) budget and energy balance of several type of bioenergy crops, that have replaced sugar beet after the application of the EU sugar Common Market Organisation reform, to show their potentialities in mitigation effects. In the period 2008 -2009 have been monitorated 347 new commercial energy crops for solid and liquid bio-fuels production, that cover totally 2591 ha all over the Italy. Species utilized are: poplar, black locust, eucalyptus, sunflower, sorghum, giant reed, Ethiopian mustard and rapeseed. In order to evaluate the GHG budget of these crops, data of biomass production (seeds and/or dry matter) and management practices were collected. The CO2 stored by the vegetation, emission of CO2, CH4 and N20 coming from fossil fuel combustion, production of fertilizers and pesticides were evaluated for all the sites investigated. Considering above ground dry biomass and seeds production, GHG and energy balance result positive but we still need to consider the effect of land use change on soil carbon content. Fertilizer production and irrigation seem to be the main sources of GHG emission.
