Biofuels and GHG implications
Life Cycle Assessment of Sustainable Aviation Fuel from Macaúba Cultivation on Degraded Pastures
Short Introductive summary
The decarbonization of aviation, responsible for about 2% of global anthropogenic CO2 emissions, remains a major challenge in the energy transition. In this context, sustainable aviation fuels (SAF) from energy crops represent a promising alternative to fossil-based Jet A-1. This study quantifies and compares the life cycle greenhouse gas (GHG) emissions of SAF produced from macaúba (Acrocomia aculeata) pulp oil in Brazil relative to conventional jet fuel, considering six technological scenarios. The Life Cycle Assessment (LCA) followed ISO 14040 and 14044 standards using SimaPro software. The functional unit was 1 ton of SAF consumed, with system boundaries defined as cradle-to-grave and impact assessment based on the ReCiPe 2016 Midpoint (H) method. Emissions ranged from 1,380 to 374 kg CO2-eq per ton of fuel, corresponding to reductions of 64% to 90% compared to fossil jet fuel. The results highlight the potential of macaúba-based SAF to mitigate GHG emissions in aviation and support global decarbonization goals.
