Spatially Explicit Assessment of Suitable Conditions for the Sustainable Production of Aviation Fuels in Brazil

International civil aviation strives to significantly reduce its greenhouse gas (GHG) emissions, and the use of Sustainable Aviation Fuels (SAF) is an alternative for such purpose. However, fuel be considered SAF, some conditions must met, production certified sustainability. This paper presents assessment necessary sustainable these biofuels in Brazil. It based on a geospatial publicly available database (SAFmaps) that was built with aim providing information stakeholders who would interested SAF. The geographic scope corresponds area about half country. case studies reported this are related four crop-based feedstocks (eucalyptus, soybean, sugarcane, corn), which could used SAF production, according three routes (FT, HEFA, ATJ) (Fischer–Tropsch, Hydroprocessed Esters Fatty Acids Alcohol Jet); total, six potential sites were assessed. For each crop, detailed estimates suitability biomass yields, costs. assumptions made allowed us explicitly analyse risk deforestation (production only occur displacement pastures) preservation sensitive biomes legally protected areas, addition observing restrictive imposed by CORSIA (Carbon Offsetting Reduction Scheme Aviation). To GHG transporting over long distances assumed rail or pipeline. In addition, we address alternatives minimise risks associated induced land-use change (iLUC) impacts landscape. results show through ATJ route, using ethanol produced from sugarcane corn, requires less land.
