The following ten year data were obtained from the National Union of “Ca~ neros” (UNC for its acronym in Spanish): Harvested area (ha), sugarcane productivity (t/ha), sugar yield (t/ha), cane mechanically harvested (%), cane mechanically loaded (%), burned sugarcane for harvest (%), sugar mill yield (%), raw sugar pro-
duction (t),molasses production (t), external electricity use (kWh/t cane) and petroleum consumed in sugar mills (L/t cane).
Data on agrochemical application and fuel consumption for agricultural and transportation machinery are based on interviews and questionnaires with sugarcane growers and sugar mill technicians conducted during field visits, as well as personal communications with experts.
Emissions from inputs, cane burning and the electric power grid were taken from the literature and from the BioGrace
model (European Commission, 2011)(see Tables 2 and 3 for details).
