    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.
