The Environmental and Economic Assessment

本研究旨在评估SAF的可行性，采取生命周期评估（LCA）的方法作为一个完整的航空运输系统。主要涉及三个模型：土地利用模型，生命周期评价，成本效益分析（CBA）。首先，将进行批判性和系统性的艺术文献综述。然后，在生产阶段，采用不同的土地利用模式，在不影响或取代现有粮食生产的情况下，研究农业生产力的提高。它试图保持一个平衡的农业生态系统：更大的作物多样性促进恢复力。所需的SAF数量将通过预测英国航空的航空运输流量和碳排放量来估计。将进行敏感性分析，以评估传统喷气燃料和SAF之间的权衡。此外，通过考虑所有利益相关者的观点，包括外部性（CO2、税收和劳动力机会），将在净现值中进行成本和收益分析。

This research aims to assess the viability of SAF by taking a Life Cycle Assessment (LCA) approach as an entire air transport system. Three models are principally involved: land-use models, LCA, and cost benefit analysis (CBA). First, the critical and systematic state of art literature review will be conducted. Then, for the production phase, different land-use models are taken to investigate the agricultural productivity improvement without impacting or displacing existing food production. It attempts to keep a balanced agro-ecosystem: greater crop diversity promoting resilience. The required amount of SAF will be estimated by forecasting air transport traffic and carbon emissions for UK aviation. Sensitivity analysis will be conducted to assess the trade-off between conventional jet fuel and SAF. Furthermore, cost and benefit analysis will be conducted in Net Present Value by considering all stakeholders' views including the externalities (CO2, tax revenue, and labour opportunities)
