This hearing is focused in the importance of investing in a stable supply chain for aviation production of biofuels. With the rising cost of jet fuel and the thriving American biofuel industry, we have an opportunity to help aviation by keeping costs down for the future. More importantly, production of green jet fuel will mean real economic growth and opportunity, not just in the United States but around the country. For over the past 50 years, Jet A fuel is the benchmark fuel used by commercial airlines. It's the gold standard that meets the strict requirements necessary for safe aircraft operation over a broad range of air temperatures and pressures.
