- Impact Analysis of E-kerosene on Aviation CO2 Emissions up to 2100Publication . Quaresma, Guilherme da Silva Nheu; Silva, André Resende Rodrigues da; Ferreira, Ana Filipa da Silva; Magalhães, Leandro BarbosaAmidst the global pursuit for sustainable aviation, catalyzed by initiatives such as Waypoint 2050 set forth by the Air Transport Action Group (ATAG), this dissertation scrutinizes the transformative potential of e-fuels, specifically e-kerosene, in mitigating CO2 emissions within the aviation sector until 2100. Aligned with the ambitious objectives outlined in the Paris Agreement and the International Civil Aviation Organization (ICAO) sustainable goals, the study employs the Fleet System Dynamics Model (FSDM) and an approach based on the formula from the Committee on Aviation Environmental Protection (CAEP) to forecast fuel demand and CO2 emissions. As the aviation industry charts a course towards recovery from effects of the COVID-19 pandemic, this research highlights the imperative for sustainable solutions and underscores the indispensable role of e-fuels in fostering a carbon-neutral future. The findings emphasize the critical role of e-fuels in achieving long-term sustainability goals, with a focus on production capacity and transition timelines, suggesting that a 15% annual e-kerosene production rate could lead to carbon-neutral growth by 2046 and cut emissions by half around 2061 concerning 2005 levels, emphasizing the need for industry adjustments to ensure a sustainable future. The study underscores the importance of e-fuels, alongside technological advancements, in meeting ambitious climate targets while accommodating the aviation sector’s continued expansion.
