Sustainable Aviation Fuel (SAF) is a cornerstone of the aviation industry's transition to net-zero emissions by 2050, with projections indicating it could contribute up to 65% of total emissions reductions. Global SAF demand is expected to rise to 18 million tonnes by 2030 and 350 million tonnes by 2050, driving significant investment in production capacity, technology, and infrastructure. This whitepaper provides a comprehensive analysis of the world’s 50 most significant SAF projects, examining their geographic distribution, technological pathways, production capacities, and operational timelines, offering valuable insights for policymakers, industry stakeholders, and investors navigating the future of sustainable aviation.
