Workshop on Sustainable aviation fuel (SAF) Futures: Innovations, Challenges and Social Dimensions
Congratulations to Sai BRAVO on her intervention on 12 December at the Institute for Sustainable Aviation (ISA) workshop « SAF Futures: Innovations, Challenges and Social Dimensions ». This full-day event brings together leading experts from research institutions, industry, and regulatory bodies to explore the technological, economic, and policy challenges shaping the SAF landscape.
The Institute for Sustainable Aviation (ISA) is a collaborative research structure (ISAE-SUPAERO, TSE, UTC, ENAC, TBS, Météo-France, CERFACS and UT2J), it aims to address the issue of aviation sustainability by implementing interdisciplinary research at the interface of social sciences and humanities, financial and industrial economics, aerospace engineering and flight operations, transport and environmental laws and regulations, energetics and atmospheric physics.
🧐 Presentation and paper of Sai:
Reducing the level of carbon dioxide (CO2) emissions in air transport calls for policies supporting less polluting fuels. The International Civil Aviation Organization and the European Union have launched policies to support the adoption of sustainable aviation fuels (SAFs). Although Article 15 of the 1944 Chicago Convention forbids the use of discriminatory charges, Article 3 of the European Union’s Airport Charges Directive allows charge modulation if related to matters of public interest, such as climate change mitigation. Recently, Lyon, Stuttgart, and airports within the Swedavia AB have implemented a CO2-based aeronautical charges modulation.
The paper studies the impact of authorizing such differentiated charges in the context of intermodal competition.
They find that with uniform tariffs, airlines have no incentive to use SAFs. Instead, if a regulator authorizes discriminatory aeronautical charges, airlines may have the incentive to use more environmentally friendly fuel. Furthermore, when the cost of SAF is small compared to passengers’ disutility from not traveling with their preferred transportation mode, then discriminatory charges increase air transportation's market share.
