@JukkaHeinonen9 and I have edited a just-published, new #openaccess issue of @CogitatioUP on relationships between cities, long-distance travel, and climate impacts: bit.ly/3pv3gVz It features seven papers on this important but understudied topic. A thread 1/X 
Two papers (by @giulio_mattioli et al. and @MartinThomasFa1 & Eva Hagsten) show that residents of large capital cities fly much more than do others. @giulio_mattioli et al. explain it by airport accessibility, migration background, and dispersion of social networks.
Flying and associated emissions are very unevenly distributed in societies: a large proportion of people do not fly at all, and a small minority generates much of the traffic and emissions.
A common assumption is that the high mobility of urban dwellers results from the lack of green spaces which make people escape the city. In the paper with @J_J_Johanna, we find that hectic schedules and stressful commutes, also motivate trips to seek calmness in the countryside.
In our paper, car‐free lifestyles did not seem to lead to increased spending on flights, even though lack of a car limits access to domestic leisure travel to some extent. @giulio_mattioli et al. also did not find rebound effects between car ownership and flights.
Pukhova et al. apply agent‐based modeling to long‐distance travel emissions in Germany to estimate and illustrate the potential of reducing emissions via air travel demand reduction. Among the ways to achieve it are increases in ticket prices and restricting short‐haul flights.
Aviation emissions are often treated as exterritorial, not assigned to any locality. @KBoussauw & Decroly highlight the role of allocating emissions caused by international travel to territorial units, such as urban regions and municipalities, based on the case of Brussels.
The scale of aviation emissions is huge. The official climate footprint of the Brussels-Capital Region was 3.7 Mton CO2eq per year in 2017. @KBoussauw calculate the total estimated climate footprint of all Brussels-bound international travel as an additional 2.7 Mton CO2eq
@m_sahakian et al. study co-designing a city‐wide initiative aiming at reducing flights in Geneva. They see much value in going beyond individualistic approaches and understanding flying as a social practice embedded in infrastructures, technologies, social norms, and meanings.
@NinaWormbs and @MariaWolrath study the processes in which Swedish residents decided to quit or reduce flying. They highlight the role of knowledge about the climate impact of flying in motivating change, particularly when internalized through experience or emotional distress.
@NinaWormbs & @MariaWolrath also show how fear and guilt had important roles, while shame was rarely mentioned, contrary to certain claims. Decisions to reduce or quit flying were often deeply embedded in social networks and connected to notions of morality and climate justice.
Might be of interest to @StefanGossling, @SaraUllstrom, @LarssonJorgen66, @keithalexander, @mmbuchs, @KA_Nicholas, @_chris_brand_, @kristinlinnerud, @SebastienMunafo, @TimSchwanen, @VincentKaufmann. You can find all the papers here: cogitatiopress.com/urbanplanning/….
