- Summary:
- This study aims to quantify, through Monte Carlo simulation (100,000 iterations), the greenhouse gas (GHG) emissions associated with the complete production cycle of ethanol from sugarcane in Brazil, expressed in kg CO2eq/ha, and to project these emissions over a 20-year horizon. To achieve this, the production cycle was segmented into distinct stages - land use change, soil management and preparation, fertilization, harvesting and straw management, soil carbon sequestration, and industrial processing - and the parameters for each stage were defined based on recent. Three representative scenarios were considered: Worst-case (unsustainable practices involving conversion of native vegetation, high fertilizer dosages, and complete burning of the straw), Typical (conventional practices, with conversion of degraded pastures and sustainable management), and Ideal (best practices, characterized by reduced input dosages, the use of nitrification inhibitors, and high straw retention). The results indicate that, under sustainable practices, ethanol exhibits a significantly lower carbon footprint compared to gasoline, whose typical emissions range between 2.8 and 3.0 kg CO2eq/L. These findings reinforce the potential of Brazilian ethanol to contribute to GHG emission reductions and underscore the importance of adopting sustainable agricultural practices
