Sustainable Aviation Fuels (SAFs) are emerging as a key tool to cut aviation emissions, which are hard to electrify. Made from waste oils, agricultural residues, or captured carbon, SAFs can reduce lifecycle carbon emissions by up to 80 percent compared to conventional jet fuel. Airlines and governments are investing in production capacity, but challenges remain: limited supply, higher costs, and ensuring feedstocks are sourced sustainably without competing with food production. This article from vocal.media covers the basics of SAFs, industry momentum, and the hurdles to scaling up. It also notes that SAFs are part of a broader strategy that includes hydrogen aircraft and efficiency improvements. For anyone tracking carbon markets or climate tech, this is a solid overview of where aviation decarbonization stands today and what still needs to happen to make SAFs a mainstream solution.
