The emissions reduction potential of substituting short-haul flights with non-high-speed rail (NHSR): The case of Finland
2021
Abstract Replacing short-haul flights with high-speed rail (HSR) has been widely discussed as one solution to mitigate the climate change impacts of aviation. However, although HSR can provide travel times similar to those provided by short-haul flights, and at lower emission levels, it also requires considerable investments in time and infrastructure to build. Instead, this study considers the feasibility of replacing short-haul flights with existing non-high-speed rail (NHSR). Our study is based in Finland, a country that has an extensive route network of short-haul flights but does not possess any HSR. We compared all 16 city pairs for which short-haul flights are offered with existing N…
‘Each flight is different’ : Carbon emissions of selected flights in three geographical markets
2017
Abstract Air travel is considered the biggest individual climate sin. Avoiding flying, however, seems impossible. In this paper we argue that the flight a passenger chooses can be significant. For this purpose we compared the carbon emissions of selected flights in three geographical markets. We found tremendous differences in the environmental performance of individual flights. Furthermore, we also found that flying with the most modern aircraft or flying non-stop represents, in many cases, the least polluting option. Nevertheless, we were able to show that there are exceptions to this rule. Based on our results, we provide recommendations to the industry and for further research.
Practices of Writing in Ethnographic Work
2020
Although the practice of writing is key to the production of ethnographic knowledge, the topic remains understudied. Using material from our own ethnographic research in the fields of air travel and cultural heritage as data, we develop a reflexive account of ethnographic writing. We examine in detail the practices of jotting down observations, writing field notes, analytic annotating, ordering and rearranging, and drafting and revising papers. The article takes a praxeological stance, conceptualizing writing as a practice that is simultaneously cognitive, embodied, and material. Our analysis finds that writing influences and shapes all stages of ethnographic work, from orienting perception…
Neonatal outcome following long-distance air travel for fetoscopic laser coagulation treatment of twin-to-twin transfusion syndrome
2011
Abstract Objective To investigate the impact of undertaking long-distance air travel to a specialized medical center while pregnant in order to undergo fetoscopic laser coagulation (FLC) for twin-to-twin transfusion syndrome (TTTS). Methods A retrospective cohort study was conducted of women with TTTS who travelled by air (n = 16) or land (n = 61) to the Centre of Perinatal Diagnosis and Microinvasive Fetal Surgery, Mainz, Germany, between January 1, 2006, and December 31, 2010. All women underwent FLC on arrival at the study center. Neonatal outcome, postoperative neonatal survival rates, and rates of adverse effects were recorded. Results The postoperative survival rate for a single twin …
Risk estimation for air travel-induced malaria transmission in central Europe – A mathematical modelling study
2019
Abstract Background Aim of our study was to identify conditions under which malaria transmission caused by imported infectious mosquitoes or travellers could occur at large central European airports, and if such transmission could be sustained by indigenous mosquitoes. Methods We developed a deterministic and a stochastic compartmental Susceptible-Exposed-Infectious-Recovered-Susceptible (humans)/Susceptible-Exposed-Infectious (mosquitoes) model with two mosquito (imported Anopheles gambiae, indigenous A. plumbeus) and three human (travellers, airport personnel exposed/not exposed to imported A. gambiae) populations. We assessed various scenarios to identify combinations of model parameters…
Multi-scale analysis of the European airspace using network community detection
2014
We show that the European airspace can be represented as a multi-scale traffic network whose nodes are airports, sectors, or navigation points and links are defined and weighted according to the traffic of flights between the nodes. By using a unique database of the air traffic in the European airspace, we investigate the architecture of these networks with a special emphasis on their community structure. We propose that unsupervised network community detection algorithms can be used to monitor the current use of the airspaces and improve it by guiding the design of new ones. Specifically, we compare the performance of three community detection algorithms, also by using a null model which t…
The effect of an eco-label on the booking decisions of air passengers
2022
Abstract In the last few years there has been an increasing attempt to find solutions on how to mitigate the environmental impacts of air travel. Behavioral change has hereby been identified as the measure with the most significant impact. One way to encourage behavioral change is the use of eco-labels. Eco-labels have, to date, received scant attention in the aviation industry, and their effect on air travel behavior is still largely unknown. This study explores the effect of an eco-label on the booking decisions of passengers. We conduct a stated choice experiment with 553 air passengers. Our findings show that providing passengers with an eco-label leads to behavioral change, as the labe…
Relational content of travel and tourism websites
2006
Developments in information technologies are having a far-reaching impact on the travel and tourism industry. This paper analyses the use of the internet as a relational tool for travel and tourism companies providing air travel and rent-a-car services. The empirical research results show the role the internet plays in increasing sales and how companies use different relational tools to gain consumer trust and commitment.
Replacing short-haul flights with land-based transportation modes to reduce greenhouse gas emissions: the case of Finland
2019
Even though air travel often provides the fastest transport option, it also has the highest climate impact. Especially on long-haul trips, an aircraft usually represents the only feasible option. Nevertheless, aircraft are more often used on short-haul routes as well. It is the short-haul flights that produce the highest emissions per passenger. These are also the ones that could be replaced the most easily by land-based transportation modes. This study investigates the greenhouse gas emissions reduction potential of replacing short-haul flights with train, coach and car travel within Finland while also taking into account real travel times from door to door. Our results showed that replaci…
