A lifelong aviation enthusiast who joined&nbsp;AIN&nbsp;in 2007, Curt came to&nbsp;the publication&nbsp;from the broadcast industry where he was a national science and technology television reporter and producer. He writes on the FBO field, aviation finance, and sustainable aviation and occasionally contributes to&nbsp;AIN&nbsp;sister publication&nbsp;Business Jet Traveler. Curt was a member of the AINtv reporting staff that won the 2008 Aerospace Journalist of the Year award for Best Airshow Daily. That same year, he was a finalist for another AJOYA award. He earned an AJOYA for Best Business Aviation Submission in 2018 and was a finalist in that category in 2021. He received the National Air Transportation Association’s&nbsp; Aviation Journalist Award in 2012 and won a Pegasus Sapphire Business Aviation Award for outstanding journalism in 2021.
Before joining AIN, Curt worked with&nbsp;Consumer Reports’ television division, CRTV, and for several local television news staffs. An honors graduate of the State University of New York at Stony Brook, he earned a master’s degree in broadcast journalism from Boston University in 1995. Curt lives in New York State with his wife and two young sons.

A recent report from investment analyst Jefferies shows that not all sustainable aviation fuels (SAF) are the same in terms of its environmental benefits, which can vary significantly depending on which of 11 approved pathways is used to produce them.
Jefferies based its findings on a discussion it hosted with International Air Transport Association (IATA) SAF specialist Daniel Bloch on policy approaches for increasing SAF production and availability. With a wide variety of feedstocks available, some production pathways—and the feedstocks they use—offer significantly better CO2 reduction in their lifecycles, Bloch noted.
For example, using new vegetable oil (as opposed to used cooking oil) as a feedstock for the HEFA process provides only up to a 20 percent savings in carbon emissions compared to Fischer-Tropsch-derived SAF from CO2 and hydrogen using renewable energy, which could bring that number to near 100 percent savings.
Most existing SAF production refineries are using the HEFA process. The report pointed out that while new projects using alcohol-to-jet (ATJ) and Fischer-Tropsch pathways have higher initial capital costs, their operational costs are lower. As a result, production facilities based on those technologies will take longer to achieve scale production. However, according to IATA, these are key to generating increasing volumes of SAF because their third-generation feedstocks are less constrained.
SAF will play a large role in IATA’s goal of net-zero emissions by 2050 and is predicted to provide 65 percent of the overall emission reduction equation. The organization notes that the supply of the fuel will be heavily region-specific, and it is currently not scaled sufficiently to be cost-competitive with conventional jet-A. Bloch sees 2025 as a potential turning point in SAF production, with European policy measures such as the <a href="https://www.ainonline.com/aviation-news/business-aviation/2023-06-05/uk-proposes-sustainable-aviation-fuel-mandate-2025">UK SAF blending mandate</a> and <a href="https://www.ainonline.com/aviation-news/air-transport/2023-06-19/eu-sets-worlds-largest-saf-blending-mandate">ReFuel EU</a> set to commence.
