The functional unit is defined as 1 kg of sugar at the sugar mill gate. We considered just the main greenhouse gases, CO2,
CH4 and N2O (with global warming potential of 1, 23 and 296 respectively), considering a time horizon of 100 years (European Commission, 2011). Other GHGs were excluded from the calculation since they contribute with only a small portion of global emissions (about 2%) (IPCC, 2014b).
