The Carbon Footprint of Travelling to International Academic Conferences and Options to Minimise It

Abstract

This chapter focuses on the carbon footprint of travelling to academic conferences. The cases I present are the last seven General Conferences of the European Consortium for Political Research (ECPR), which are the biggest European conferences in political science, with up to 2000 participants. My estimations show that the travel-induced carbon footprint of a single conference can amount to more than 2000 tons of greenhouse gases-as much as approximately 270 UK citizens emit in a whole year. The average participant produces between 500 and 1500 kg of CO2-eq per conference round-trip. However, by applying three measures (more centrally located conference venues, the promotion of more land-bound travel and the introduction of online participation for attendees from distant locations), the carbon footprint could be reduced by 78-97 per cent. In 2020, the COVID-19 pandemic caused a general shift towards online conferences-the ECPR switched to a virtual event as well. Estimating the carbon footprint of this online-only conference in a more detailed manner shows that the travel-induced carbon emissions-if the event had taken place in physical attendance as originally intended-would have been between 250 and 530 times higher than those from the online conference.
