 Mathieu Blondel, Arthur D. Little, partner, head of the Aviation competence center

Round table 1: The climate challenge from the operators’ point of view

Are pre-crisis solutions up to the challenge; is there not a need for disruptive changes in the practice of the profession?


Moderator : Paul Steele, air transport advisor, former Environment director IATA

  • Michael Gill, executive director, Air Transport Action Group (ATAG)
  • Nancy Young, vice president Environmental affairs, Airlines for America

Question and answer session

Round table 2: International perspective, institutional stakes

Are European ambitions compatible with those of the rest of the world and is there not urgency in finding a new balance between regulation and liberalisation ?

Moderator : Paul Steele, air transport advisor, former Environment director IATA

  • Michel Wachenheim, president of Air and Space Academy, former representative of France at ICAO
  • Adefunke Adeyemi, regional director, Advocacy and Strategic Relations – IATA Africa

Question and answer session

Session 4. Mobility of the future on a global scale

 Presentation of themes and introduction of speakers by the session chair

Eric Dautriat, Air and Space Academy (AAE)

Travel: a given of civilisation – The evolution of air transport uses.

Is the use of long-distance travel linked to the model of Western society, or to a deep anthropological need? What are its sociological characteristics at the global level? In the field of “mass tourism”, what role is played by the desire for discovery, on the one hand, and the demonstration of social status on the other? What role can citizens’ climate concerns play in the future in the evolution of usage, and what paradigm shifts can they induce for air transport itself, in particular under the possible catalytic effect of the health crisis?

François Gemenne, director of the Hugo Observatory at the University of Liège, member of the IPCC, lecturer in Political Science

Stefan Gössling, professor at Lund University

Public policies for sustainable mobility. What are the parameters that govern mobility, and on what levers can public policies act to change mobility (especially air transport) in the direction of global decarbonization?

Yves Crozet, professor of Economics at the Institute of Political Studies of Lyon

Question and answer session

Round table: Geopolitics of attitudes towards the air transport of tomorrow

  • What is the anticipated importance of future air transport?
  • What priority is given to the question of its impact on the climate in the different ragions of the world?
  • What model of society, globalisation, new behaviours can (or must) lead to a decarbonised world?
  • What consequences for mobility and perhaps reinvented air transport?

Moderator : Sophie Voinis, journalist

  • Andrew Murphy, Aviation director at Transport & Environment (T&E), Brussels
  • Xu Bo, former Chinese diplomat, commissioner of the World Exposition Shanghai 2010
  • John Byerly, former deputy assistant secretary Transportation Affairs, US Department of State

Question and answer session
