SAF's main barrier to 2050 net zero is slow tech rollout, not feedstock supply, IATA says.
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.
Instead, the primary challenge is the slow rollout of production technologies, particularly power-to-liquid systems, which require significant investment and infrastructure.
Current SAF output relies mostly on limited technologies like HEFA, while competition from other industries and underdeveloped supply chains further hinder progress.
IATA urges governments to provide policy support, harmonized regulations, and long-term incentives to accelerate SAF deployment.
Concerns remain over the sustainability of some feedstocks, such as beef tallow linked to deforestation, prompting exploration of alternative sources like invasive sargassum algae.
La principal barrera de SAF para alcanzar el cero neto en 2050 es el lento despliegue de tecnología, no el suministro de materia prima, dice la IATA.
