The agricultural stage includes the following sources of emissions: From fuel used for farm machinery, from the production of fertilizers and pesticides, nitrogen monoxide (N2O) emissions from nitrogen fertilizer volatilization (calculated as 1% of the N applied;IPCC, 2006), emissions from energy for irrigation, from harvest machinery and from sugarcane burning for harvesting. The industrial stage (sugar milling and sugar conversion) includes emissions from electricity generation and fuel use. Emissions from transport correspond to the use of trucks for carrying sugarcane (Fig. 1).
