Sustainable aviation fuel is gaining popularity among renewable fuel manufacturers. The SAF market is poised for rapid growth in the coming years as global and regional emissions programs look to decarbonize the carbon-intensive aviation sector.

However, the market faces additional hurdles like competition for feedstocks and high production costs. Senior oil writer Janet McGurty and Americas biofuels manager Josh Pedrick talk through the emerging trends in SAF and some of the challenges facing the market.
