Sustainable aviation pathways after Covid19

By Alejandro González, URV phd researcher

Aeromobilities during Covid-19 have been highly disrupted due to the unprecedented global lockdown and the subsequent border restrictions, affecting the entire value chain of travel and tourism, with dramatic impacts on local economies that are most dependent on the visitor economy.  Yet, the desirability that air travel returns to the pre-pandemic trends has been critically questioned by one of the major authors in the field of sustainability transitions and mobilities, Stefan Gössling of the Western Norway Research Institute. In his newly published paper, Risks, resilience, and pathways to sustainable aviation: A COVID-19 perspective (Journal of Air Transport Management, 89), he questions if the volume growth model championed by the aviation industry and its travel and tourism allies ought to be replaced with a slimmed air transport system, less vulnerable to global shocks and more accountable for its environmental impacts. This alternative would disrupt the “back to business as usual” ambitions of the tourism industry, as air transport moves the 58% of international tourism arrivals but would represent a decisive breakthrough towards a low-carbon transition of tourism mobilities.

Billions of US$ have been allocated to recovery plans for airlines and airports (T&E, Greenpeace & Carbon Market Watch, 2020), with hopes to expediently return to business-as-usual (ICAO, 2020). At the end of May 2020, the total volume of State aid may have exceeded US$100 billion, i.e. almost half of what global airlines reported as their net result over nine years, i.e. for the entire period 2010–2018 (US$196.9 billion; IEA, 2019).

However, Gössling highlights that this crisis is a reminder of long-standing, interrelated and unresolved problems characterizing the global air transport system. Air travel is a major contributor to climate change (an estimate of 5% global warming, IEA 2019), and a vector of pathogen distribution, within very short timeframes (Browne, St-Onge Ahmad, Beck & Nguyen-Van-Tam, 2016). Besides, the sector’s small and often negative profit margins (Doganis, 2005; Gössling and Higham, 2020; IATA, 2019a,b) are highly dependent of State aids (Doganis, 2005; Gössling et al., 2017). Recent research also hints at adversely distributive features of air travel: only a small proportion of the world population participates in international aviation. So, cheap flight could hardly be considered a means of social empowerment, while carbon inequality has big implications to climate justice.

Therefore, how should the return of aviation be? IATA (2020) expects that the recovery after COVID-19 will take some time, but a return to business-as-usual is nevertheless expected. Conversely, an alternative scenario towards a desirable and resilient aviation system, the baseline is that air transport capacity is diminished, risks and vulnerabilities are taken into account, and the cost is integrated into pricing plans and weighed against short-term benefits.
