1. Alternative Fuels Task Force

2. The Task
Evaluate the range of potential greenhouse gas emissions reductions from the use of alternative fuels in aviation u to 2050.
In order to fulfill this:
Develop and use ranges for lifecycle greenhouse gas emissions for different groups of altenative jet fuels
Assess the potential alternative jet fuel availability in the short- (2020) and in the longrun (2050) perspective.
Combine the outcome in order to calculate the potential emissions reductions by using alternative fuels.

3. Reports
Fuel Production Assessment Report – calculate the availabilitity of alternative fuels
Life Cycle Assessment Methodlogy - assess the life-cycle emissions
Fuel Production Assessment Summary – caluculations for 2020 and 2050
The work started in 2013 and will be completed in time for CAEP-meeting in february 2016.

4. Preliminary results
2020 – green diesel is most important for the availability of alternative fuels
many scenarios are calculated and they result in 0 – 100 % availability of alternative fuels!
The availabilty depends on policies, support etc and the scenarios needs to be considered combined with the possible policies in place.
Ongoing work to describe the results.

5. Additional Task
Develop a Life cycle assessment (LCA) methodology for the purpose of accounting for the emissions derived from the use of of alternative fuels in international aviation in a Global-Market-Based (GMBM) Monitoring, Reporting and Verification System.
The work started in january 2015 and will be completed during next CAEP-cycle.

6. Report
Methodology for the Assessemet of Life Cycle Emissions from alternative jet fuels for use in the global market based mesure system
Many topics under diskussion, for example:
How to define and handle Carbon Hotspots
How to handle LUC (land use change) and ILUC
What amortization period should be used?
Reduction tresholds?
