Introduction. Fossil combustion and fertilizer
decomposition are the main sources of greenhouse
gas emissions in sugarcane crops.Objective. Perform
a comparative analysis of Carbon Footprint
scenarios in commercial and organic sugarcane
crops. Materials and Methods. Carbon Footprint
was calculated based on IPCC Guidelines; emission
projections were obtained through system dynamics
and the opportunities for emissions reductions were
obtained with sensitivity analysis. Results. The first
CO2 emission model for fossil combustion obtained
a level of 1.87 tCO2
-eq/ha in a commercial crop and
1.67 tCO2
-eq/ha in an organic crop, projected for 25
years. The second N2
O emissions model for fertilizer
decomposition achieved a level of 6.18 tCO2
-eq/
ha in a commercial crop and 4.62 tCO2
-eq/ha in an
organic crop, simulated for 5 years. Conclusion. The
adoption of specific agricultural practices in each
agro-ecological zone represents an opportunity to
reduce CO2 emissions, which corresponds to 31% for
commercial crop and 0.49% for organic crop. A proper
fertilizer application according to soil characteristics
and the crop’s harvest cycle contributes to reducing
N2
O emissions by up to 40% for commercial crop and
25% for organic crop.
