Sustainable aviation fuels key to decarbonizing air travel

Sustainable aviation fuels (SAFs) are crucial for decarbonizing air travel. Made from sources like used cooking oil, SAFs can replace Jet A-1 fuel, emitting less carbon. Challenges include scaling up production, costs, and impact on feedstock availability. SAFs reduce emissions by up to 80%, but costs are high. Traditional fuel producers are not heavily investing, leaving room for specialist start-ups like Neste and Gevo to lead the way.
