Abstract

Sustainable aviation fuel (SAF) contributes to 65% of all efforts from the airline industry to mitigate carbon emissions. Nonetheless, studies yet to consider SAF in fuel loading problems for environmental benefit. Additionally, book-and-claim is not considered in current optimization studies for airlines to have an option to virtually purchase SAF when it is not available or too expensive in a location to offset carbon emissions. An optimization model is developed for an airline fuel loading decision support system that considers SAF by optimizing cost and environmental impacts simultaneously, integrating the strategies and policies for implementing the use of SAF. A case study was used to test the model to understand its behaviour. Scenario analyses were conducted to highlight potential economic and environmental benefits from optimally managing SAF and book-and-claim. The developed model demonstrates a 17.16% decrease in environmental impact considering a maximum SAF blend of 10%, which highlights the potential of SAF to decarbonize the aviation industry. Mandates set by the government are helpful as airlines tend to result to fuel tankering when fuel costs are high. Book-and-claim is helpful when SAF is expensive in certain airports as airlines can virtually purchase SAF to save on costs.

考虑到可持续航空燃料和 "先订后取",对航空公司燃料装载问题进行多目标优化
可持续航空燃料(SAF)占航空业减少碳排放努力的 65%。然而,有关研究尚未考虑在燃料装载问题中使用 SAF 以实现环境效益。此外,在目前的优化研究中,还没有考虑让航空公司在某地没有可抵消碳排放的 SAF 或 SAF 太贵时,可以选择虚拟购买 SAF。为航空公司燃油装载决策支持系统开发了一个优化模型,该系统通过同时优化成本和环境影响来考虑 SAF,并整合了使用 SAF 的策略和政策。利用案例研究对模型进行了测试,以了解其行为。还进行了情景分析,以突出优化管理 SAF 和账面索赔的潜在经济和环境效益。所开发的模型显示,考虑到最高混合 SAF 为 10%,对环境的影响减少了 17.16%,这凸显了 SAF 在航空业去碳化方面的潜力。政府制定的规定很有帮助,因为当燃料成本较高时,航空公司倾向于使用油箱。当某些机场的 SAF 价格昂贵时,"即订即领 "服务很有帮助,因为航空公司实际上可以购买 SAF 以节省成本。

期刊介绍: The Journal of Cleaner Production is an international, transdisciplinary journal that addresses and discusses theoretical and practical Cleaner Production, Environmental, and Sustainability issues. It aims to help societies become more sustainable by focusing on the concept of 'Cleaner Production', which aims at preventing waste production and increasing efficiencies in energy, water, resources, and human capital use. The journal serves as a platform for corporations, governments, education institutions, regions, and societies to engage in discussions and research related to Cleaner Production, environmental, and sustainability practices.
