On May 7, 2014, the U.S. Government Accountability Office (GAO) released a report on "Alternative Jet Fuels: Federal Activities Support Development and Usage, but Long-Term Commercial Viability Hinges on Market Factors." GAO found that [a]chieving price competitiveness for alternative jet fuels is the overarching challenge to developing a viable market." To this end, according to stakeholders consulted for the report, both federal activities -- including policy stability -- and market factors contribute to the ability of alternative jet fuels to be priced competitively with traditional jet fuels. A copy of the report is available online.
