Since its announcement in September 2021, the Sustainable Aviation Fuel (SAF) Grand Challenge has had a significant impact in accelerating the acceptance and growth of SAF as a primary strategy in aviation decarbonization.

The U.S. Environmental Protection Agency (EPA) collects renewable fuel data as part of the Renewable Fuel Standard, which provides an approximate consumption for novel biofuels such as SAF. EPA's data show that approximately 5 million gallons of SAF were consumed in 2021, 15.84 million gallons in 2022, and 24.5 million gallons in 2023.

2025年1月13日 · Newly updated metrics in this Progress Report show that 30 million gallons of SAF have been produced domestically in the first three quarters of 2024, up from 5 million gallons in 2021. Currently announced domestic projects represent over 3 billion gallons of annual SAF production capacity — representing $44 billion of announced funding— by 2030.

2025年1月13日 · The progress made by these federal agencies supports the interagency SAF Grand Challenge, including new funding opportunities and initiatives aligned with the SAF Grand Challenge Roadmap; providing expertise and technical assistance to industry; increasing interagency collaboration; and providing data, modeling, and analysis to decision makers.

2025年1月16日 · 新的《2021-2024年进展报告》以可持续航空燃料大挑战路线图为基础，该路线图旨在扩大SAF生产规模，将温室气体（GHG）排放量减少至少50%；到2030年生产30亿加仑（≈113.6亿升）的SAF；到2…

The SAF Grand Challenge will guide federal actions to support industry to reduce the cost, enhance the sustainability, and expand the production and use of SAF to meet the following goals: A minimum of a 50% reduction in life cycle greenhouse gas (GHG) emissions compared to conventional fuel.

SAF is a liquid fuel currently used in commercial aviation which reduces CO2 emissions by up to 80%. It can be produced from a number of sources (feedstock) including waste oil and fats, green and municipal waste and non-food crops. It can also be produced synthetically via a process that captures carbon directly from the air.

2022年9月23日 · SAF has the potential to deliver the performance of petroleum-based jet fuel, but with a fraction of its carbon footprint – emerging SAF pathways even have a net-negative GHG footprint. SAF can be made from renewable biomass and other resources, including winter oilseed crops, agricultural and forestry residues, and municipal solid waste streams.

2024年12月12日 · 美国航空业排放占温室气体排放总量比约3%且预计增长，需大规模使用低碳燃料，SAF是短期内可行脱碳方案。 2021年美国发起 “SAF 大挑战”，设定了2030年和2050年的生产目标，即到2030年生产30亿加仑/年SAF以满足10%的航空燃料需求，到2050年生产350亿加仑/年SAF以满足100%的预计航空燃料需求。 除了与减少温室气体排放相关的益处外，扩大SAF的生产规模还会对经济、社会和环境产生积极影响。 报告旨在为公共和私营部门加快SAF商业化提 …

2024年12月17日 · 2021年发布《2030年前碳达峰行动方案》，将航空业纳入碳市场重点碳排放行业名单，大力推进SAF等替代燃料发展；2022年《“十四五”民航绿色发展专项规划》提出，力争“十四五”期间SAF消费量达到5万吨、2025年当年达到2万吨，相较于我国约3000万吨/年的航油 ...
