Purpose/Objective:

It is known that travel, especially air travel, has a large carbon footprint which makes climate change worse [1] but his can be reduced by over 90% by travelling by train rather than flying [2]. Academics and healthcare professionals attend international meetings to ensure their practice is up to date, to network and share ideas. However, this travel has an associated carbon footprint. The annual ESTRO Congress has around 6,000 attendees each year which is likely to have a large carbon footprint. Methods like regional hubs, where several smaller conferences are held simultaneously have been shown to reduce this environmental impact in other disciplines [3]. This study aimed to estimate the carbon footprint of travel to and from the annual ESTRO congress in 2023 and the impact of potential means of reducing it in the future.

Material/Methods:

A list of the number of delegates from each country for ESTRO23 in Vienna was used as the basis of this work. An in-house python code was used to determine the straight-line distance from the main city within the attendees’ country to Vienna. In addition to this the results of a post-ESTRO23 survey (completed by 7% of attendees) recorded how they travelled and was used to estimate the proportion of people travelling by train for a given distance. For train travel the straight-line distance was multiplied by a detour factor of 1.4 as trains tend to go via
