The aviation industry strongly supports the introduction of alternative jet fuels that have the potential to provide environmental, economic, and security-of-supply benefits compared to conventional fuels. These fuels are expected to be drop-in fuels, meaning that they can be used in existing aircraft and supporting infrastructure. Some airlines have started taking delivery of alternative jet fuel at Los Angeles International Airport (LAX), and other similar commercial arrangements are expected in the near future. As alternative jet fuels start to enter the supply chain, there may be a need to keep track of such fuels for technical (e.g., quality control, fuel efficiency); regulatory (e.g., tracking reductions in local air quality pollutants or greenhouse gases); and commercial (e.g., contract verification, corporate social responsibility marketing/sustainability reporting) reasons. A logical point to institute fuel-tracking mechanisms may be at the airport because the supply chains for conventional and alternative jet fuels converge before the fuel gets loaded into the aircraft. Airports can play a key role to incentivize the commercialization of alternative jet fuels by helping to facilitate some of the logistics associated with using these drop-in fuels, in particular fuel tracking. This report provides guidance to help airports and other interested stakeholders identify the potential needs for effectively and efficiently tracking alternative jet fuel into the airport. This guidance, along with a companion decision-support tool (available on the Transportation Research Board website), compares different types of tracking mechanisms and evaluates their advantages and disadvantages, impediments to implementation, and potential impacts. |
