Report says high aviation biofuel costs and regulation over airport spending obstacles for fuel uptake

In Washington state, the two biggest challenges facing broader adoption of sustainable aviation fuel at Sea-Tac are the higher cost compared with petroleum jet fuel, and the constraints imposed by state and federal regulations on use of airport funds.

A report, titled Innovative Funding for Sustainable Aviation Fuel at U.S. Airports: Explored at Seattle-Tacoma International, reveals the financial tools available to U.S. airports, and outlines legal constraints and financial impacts of each tool.

The report found that no single tool could generate enough funding to cover the higher cost of biofuel, and recommended combining a number of funding tools.
