Sustainable aviation in the context of the Paris Agreement: A review of prospective scenarios and their technological mitigation levers

Analysing the Role of the Propulsive System in the Global Civil Aviation Energy Optimisation Framework

“…The paper assumes that a first-order qualitative analysis could capture the global fleet polluting impact if the total energy expenditure thereof could be captured. This postulate is somewhat akin to the work presented by Delbecq et al in their modified version of the Kaya equation [11], as well as to the approach adopted by Jensen et al in their discussion on US-based pathways towards 2050 climate neutrality [25]. As previously succinctly introduced in [36], a clear coarse-graining of the global fleet into a number of distinct categories indexed a can be assumed.…”

“…The review was rendered as compact as possible given the sheer amount and scope of the source material, which cannot be reasonably summarised within the confines of a single paper chapter. More comprehensive reviews of industrial transition scenarios can be found in Delbecq et al [11], who provide aside from an in-depth review analyse the reviewed material against the backdrop of the Paris Agreement climate objectives. Additionally, Afonso et al [12] presented a systematic review of industrial approaches to lowering the future environmental impact.…”

“…Any of the above examples (Figs. [6][7][8][9][10][11] where different system illustrations were made with their respective Data and Model Variables could be used to illustrate practical importance of the above two types of scenarios. At the whole aeroplane level, an example illustration can be the historical development of design for noise, which until the rise of strict community norms and noise compliance norms was arguably treated in the descriptive way.…”

AeroMAPS: a framework for performing multidisciplinary assessment of prospective scenarios for air transport

“…As a result, environmental roadmaps, and more specifically, decarbonisation roadmaps, have emerged in recent years. These issues have also been at the heart of numerous academic publications in recent years as explained in [2]. Indeed, the study of prospective scenarios for air transport makes it possible to assess the effectiveness of various levers of action (new aircraft architectures, alternative fuels...) to reduce the sector's impacts.…”

Carbon-Free Fuels Can Increase Aviation-Induced Cloudiness

“…T he concept of electric aviation is driven by the growing concern over the aviation industry's contribution to greenhouse gas emissions and climate change 1,2 . To put this into perspective, the emissions produced by a round-trip flight from Lisbon to New York are approximately equivalent to the emissions generated by an average person in the European Union when heating their home for an entire year 3 , which is large enough to rank the aviation industry among the top 10 emitters in the world if it was considered a country 3 .…”
