2、r 2024-page 2/18 Preamble The need to tackle climate change will require wide-scale emissions reduction in all sectors of the economy including air travel.There are multiple activities underway in the aviation sector to drive this reduction,and a wide range of enabling technologies.In particular,the

3、 International Civil Aviation Organization(ICAO)has developed the Carbon Offsetting and Reduction Scheme for International Aviation(CORSIA),which make it possible for participating parties to reduce emissions through offsetting or the use of Sustainable Aviation Fuels(SAF).Among the different SAF pa

4、thway options,e-fuels,produced from captured carbon dioxide and green hydrogen1 will have near zero life-cycle emissions,could play an important role in the aerospace industrys decarbonisation roadmap set out by ATAG,IATA and ICAO given their potential scalability.These leading aviation authorities

5、and regulatory bodies consider SAF as a key contributor to reach net-zero carbon emissions by 2050.For reasons of technical suitability,all SAF pathways today are limited to a maximum of 50%blend ratio with fossil fuel within the controlling ASTM fuel specification.As a result,there is a need to und

6、erstand how to enable the use of 100%SAF thereby removing the need to blend with fossil fuels at all.There is an interest in e-fuels in particular,the production of which is not subject to the availability of biomass feedstocks.Understanding the technical feasibility,costs,deployment,potential const
