flag SAF's main barrier to 2050 net zero is slow tech rollout, not feedstock supply, IATA says.

flag A new IATA study finds that sustainable aviation fuel (SAF) feedstock availability is not the main barrier to aviation’s 2050 net zero goal, as sufficient sustainable sources like waste oils and biomass exist without causing harmful land-use changes. flag Instead, the primary challenge is the slow rollout of production technologies, particularly power-to-liquid systems, which require significant investment and infrastructure. flag Current SAF output relies mostly on limited technologies like HEFA, while competition from other industries and underdeveloped supply chains further hinder progress. flag IATA urges governments to provide policy support, harmonized regulations, and long-term incentives to accelerate SAF deployment. flag Concerns remain over the sustainability of some feedstocks, such as beef tallow linked to deforestation, prompting exploration of alternative sources like invasive sargassum algae.
