Definition ∞ Sustainable Aviation Fuel (SAF) refers to jet fuel produced from renewable and waste-derived biomass and other non-fossil sources, designed to significantly reduce greenhouse gas emissions compared to conventional jet fuel. SAF can be blended with traditional jet fuel and used in existing aircraft engines without modification. Its development and adoption are crucial for the aviation industry’s efforts to decarbonize. SAF production pathways include processes utilizing agricultural waste, used cooking oil, or municipal solid waste.
Context ∞ News about Sustainable Aviation Fuel (SAF) frequently highlights its critical role in achieving the aviation sector’s carbon reduction targets. Discussions often center on increasing SAF production capacity, securing supply chains, and developing supportive policy frameworks and incentives. The implementation of blockchain technology is being explored to ensure the transparency and traceability of SAF from production to consumption, verifying its environmental attributes. The widespread adoption of SAF is a key metric for assessing the industry’s progress toward environmental sustainability.
