What is Sustainable Aviation Fuels Lifecycle Assessment?
Sustainable Aviation Fuels Lifecycle Assessment evaluates the full environmental impacts, from feedstock production to aircraft wake emissions, of renewable jet fuels derived from biomass, waste, and synthetic pathways compared to fossil kerosene.
This subtopic analyzes well-to-wake greenhouse gas emissions, resource use, and economic feasibility of drop-in sustainable aviation fuels (SAF). Key studies quantify carbon intensities across production routes like Fischer-Tropsch synthesis and alcohol-to-jet processes. Over 10 papers from 2009-2023, with de Jong et al. (2017) leading at 323 citations, provide comparative data on SAF pathways.
Why It Matters
Lifecycle assessments inform CORSIA certification and EU ReFuelEU mandates by quantifying SAF emission reductions up to 80% versus fossil fuels (de Jong et al., 2017; Rye et al., 2009). They guide policy for scaling production to meet 2030 targets of 6% SAF blending, balancing supply security and planetary limits (Rye et al., 2009). Economic analyses support airline adoption amid net-zero goals, as in Dray et al. (2022) pathways to aviation decarbonization.
Key Research Challenges
Feedstock Scalability Limits
Biomass and waste feedstocks face competition with food production and land use constraints, limiting SAF to 1-5% of jet fuel demand by 2030 (de Jong et al., 2017). Studies highlight supply chain bottlenecks for Fischer-Tropsch fuels from municipal waste (Rye et al., 2009).
Well-to-Wake Emission Variability
SAF pathways show 50-90% GHG reductions, but indirect land use change can increase emissions by 20-50% in some scenarios (de Jong et al., 2017). Contrail and particulate effects add uncertainty beyond tailpipe CO2 (Beyersdorf et al., 2014).
Economic Viability Gaps
SAF production costs 2-5 times higher than fossil kerosene, hindering commercialization without subsidies (Dray et al., 2022). Lifecycle costing reveals breakeven needs carbon pricing above $100/tonne CO2 (Sacchi et al., 2023).
