Resumo

The aviation sector's decarbonization is a global priority due to its significant greenhouse gas (GHG) emissions. Sustainable Aviation Fuel (SAF), specifically the Alcohol-to-Jet (ATJ) pathway using ethanol, is a promising alternative for Brazil. This study analyzes the economic and environmental impacts of replacing traditional jet fuel (QAV) with SAF-ATJ at Brasília International Airport (SBBR), based on its estimated 2024 fuel consumption of 0.27 billion kg. Four scenarios comparing 15% and 50% SAF substitution for 2025 and 2050, considering projected fuel costs, carbon credit values, and lifecycle emission reduction efficiencies, also calculating green hydrogen demand. Currently, SAF-ATJ is about three times more expensive than QAV, but its economic viability improves significantly with the adoption of higher carbon credits prices. By 2050, with higher carbon prices (USD 250/ton) and mature production costs, a 50% SAF blend becomes competitive in comparison to 100% QAV. Environmentally, a full SAF-ATJ transition at SBBR could prevent over 711,000 tons of CO₂ emissions annually (assuming 85% reduction). Adopting SAF-ATJ is technically viable for Brazilian aviation, but large-scale implementation requires technological maturation, cost reduction, and public policies, particularly a high-value carbon market, to reduce the economic gap with fossil fuels.
