Table 1 Aggregated interview results on the status quo of flight reduction at higher education institutes covering different fields of activity and the respective concluded findings.

From: An evidence-based approach to accelerate flight reduction in academia

Fields of activity

Aggregated status quo results from the interviews

Concluded findings

Implementation of the topic of flight reduction

Flight reduction as…

- …part of a sustainability strategy

- …part of the focus field of mobility within the climate action concept

- …topic of discussion in the sustainability group (not formally embedded)

- …a university-wide project located at management level and the sustainability unit, independently of a conceptual framework

➔ The intensity of implementation of the topic of flight reduction at academic institutions ranges from soft informal to structural involvement at management level

Involvement of different institution members

Flight reduction is driven by…

- …sustainability officer

- …a scientist’s initiative

- …the cooperation with administration/travel department

- … legitimacy through management level

- …discussions in a working/sustainability group (for mobility) consisting of different institutional members

- …incentives by the international office

- …involvement of student initiatives

➔ The types of involvement on the issue of flight reduction are different at each institution and, above all, vary in intensity

Monitoring + Reporting

- No standardised collection of business trip data

- Travel reason is collected by a free text entry (hard to analyse/quantify)

- Manual transfer of travel data to calculate emissions

- Tool to measure flight emissions from business trips: atmosfair

- No collection of data from student air travel

- Aim to use new tool that facilitates monitoring of business trips/emissions

➔ The lack of digitisation and standardised collection and storage of flight data challenges the process of continuous monitoring

Flight reduction measures

- No implementation of any flight reduction measures

- Implemented air travel policy including next steps on developing measures for flight reduction

- Reduction targets for flight emissions

- Carbon offset payment for flight emissions to the federal state

- Voluntary carbon offset payment to an internal climate action fund

- Continuing expansion of virtual infrastructure

➔ No mandatory flight reduction measures are implemented yet by any of the institutions studied

Communication

- Reporting of flight reduction data within the framework of the sustainability report

- No information about the methodological approach of calculating the emissions

- Free available paper (incl. number of flight emissions and methodology)

- Different formats for information and awareness making events on the topic of flight reduction

- Discussions on the topic of flight reduction in regular meetings

➔ Education and communication on the topic of flight reduction with all member groups of the institution promote the transformation process in various ways

Challenges

- Fostering scientific success/career/quality and simultaneously reduce flight emissions

- Very small but globally connected research community

- Fieldwork at remote places

- Costs for flights vs. train

- Long travel times are not family-friendly

- Scientific communities’ culture of presence

- Possibility of networking or informal exchange is missing in virtual formats

➔ Individual challenges at each institution need to be faced
