| Synopsis: |
This presentation covers efforts to examine life cycle greenhouse gas (GHG) emissions of alternative aviation fuels, as led by the U.S. Air Force Research Laboratory with the support of a multi-disciplinary group of federal, industrial, academic institutions. The primary objective of the workgroup is to develop a set of standard guidance on how to evaluate the life cycle GHG footprint of various alternative jet fuel production pathways using a wide-range of feedstock sources. Application of the guidelines can be used by fuel suppliers, military, and commercial airlines to assess the environmental preferability of a specific fuel production pathway when compared to conventional jet fuel. Workgroup activity status and plans for testing on specific case studies are also discussed.
