ISA-LABELLED THESIS: LAETITIA BORNES HAS DEVELOPED A PROTOTYPE MODELLING TOOL
Laetitia Bornes’ thesis, awarded the ISA label in 2023, delves into a systemic approach aimed at integrating rebound effects into interactive system design.

The particularity of ISA’s research lies in the balance of disciplinary contributions between human and social sciences and exact or engineering sciences. This balance allows a global approach to highlight the interactions between the socio-economic causal sphere and the techno-physical sphere that lead human societies towards alternative futures for energy and aviation.
This upstream program aims to establish and evolve an ISA set of metrics for assessing the sustainability of the aviation sector on very broad perimeters, such as commercial aviation from upstream to downstream (energy-airline-tourism), or on a narrower segment or subset of the sector, or as a result of use changes.
This program aims to build an Integrated Assessment Model (IAM) for the commercial aviation sector (passengers and freight).This model will be the repository of partial models from other programs and data from the aeronautical system. AeroMAPS is the founding program and the integration ground for ISA’s quantitative modeling enterprise.
This program will contribute to the development of new routing models toward air traffic that delivers on the promise of increased operational efficiency and mitigates non-CO2 effects (contrails). It is also within this program that we study the impact of sustainability requirements on the travel market and airline profitability models. In addition, the TSAR program will shed light on the economic, social, and other consequences of likely global warming levels on commercial fleet operations.
By implementing a life-cycle analysis of the entire production, transportation, and consumption of SAF, this program will measure the sustainability gain and feasibility of energy pathways using various SAF as substitutes for kerosene. The economic and social implications of such a substitution will be examined on the basis of production ramp-up scenarios and inter-sectoral trade-offs for access to SAF volumes. A second component of this program consists in studying, with the same approach, the substitution of kerosene by hydrogen.
General aviation is likely to play an increasing role in low-impact continental multimodal mobility. Sustainability assessment and prospective analysis of its growth trajectory, investment and territorial infrastructure needs, acceptability issues and the colateral effect on other aviation segments and on land mobility will feed the research actions carried out in this program.
The transition to a more sustainable global fleet will likely depend on the financial attractiveness and profitability level of the sector in the new regulatory and climate context. This program will address the economic feasibility of fleet renewal in relation to airline business models, the financial capabilities of institutional and private investors and leasing operators. This core issue will be extended to the financing of technological innovation for new aircraft, of airport (fuel) infrastructure renewal and of the new sustainable ATM
