6C h a p t e r 2 2.1 Introduction to Jet Fuel Logistics and Procurement It is critical to understand three key elements needed to properly develop mechanisms for alternative jet fuel tracking: 1. Physical supply of jet fuel to the wing of the aircraft, 2.

D7566 contains two types of specifications -- one that applies to the neat alternative fuel after production and one that applies to the blend of alternative and conventional fuel.

Current and potential tracking Mechanisms 9 Three common jet fuel purchasing mechanisms are illustrated in the lower portion of Figure 2. The bars indicate the point in the supply chain at which the airline takes and retains title to the fuel.

10 tracking alternative Jet Fuel Once the fuel enters commingled storage, physical tracking is not possible, and the fuel farm operator must rely on its accounting system to determine inventory levels for each of the parties storing fuel at the farm. The fuel farm operator uses delivery receipts and fuel tickets to keep track of fuel inventories for different customers.

Current and potential tracking Mechanisms 11 2.2.1 Overview of Sustainability Certification Frameworks for Alternative Jet Fuel While no sustainability framework has been formally established for alternative jet fuels, numerous frameworks exist that potentially could be used to create mechanisms to evaluate and certify the sustainability attributes of alternative jet fuels.17,18,19 These frameworks can be divided into two broad categories: regulatory and voluntary. Regulatory frameworks are mandatory in nature and tend to apply only in those jurisdictions where the legislation exists.

12 tracking alternative Jet Fuel Factors that make physical segregation feasible include a short supply chain with fewer actors involved and physical proximity to the airport. Therefore, physical segregation is easier to implement for aviation fuel if the alternative fuel production facility is located on or near airport property.

Current and potential tracking Mechanisms 13 The main attributes of mass-balance are: • It allows for traceability at each stage of the supply chain; • It may allow airports where alternative jet fuel is dispensed to claim reductions in air pollutants such as particulate matter (PM) and sulfur oxides; and • It is easier to avoid double counting than in book-and-claim.25 Book-and-Claim In book-and-claim, sustainability information related to the alternative fuel is decoupled from the physical product at some point along the supply chain.

14 tracking alternative Jet Fuel Hybrid Chain of Custody In practice, some situations might suggest shifting the CoC approach at defined points between raw feedstock and aircraft wing. A hybrid CoC approach may be used in order to simplify CoC tracking and meet several voluntary standards and alternative fuel requirements of multiple jurisdictions all at once.
