A little more conversation, a little more action, please: the carbon footprint of travelling to conferences of the European Health Psychology Society.

INTRODUCTION

The environmental impact of on-site conferences, with air travel as the primary contributor to greenhouse gas emissions, has prompted a surge in research in recent years. The objective of this report is to raise awareness and stimulate transformation in the organisation of meetings of the European Health Psychology Society (EHPS).

METHODS

We conducted estimations of travel-related COeq emissions of EHPS conferences in 2019, 2022, and 2023, and performed projections for 2024 and 2025. Additionally, we developed hypothetical scenarios for selected European cities as centroids for future conferences.

RESULTS

EHPS conferences with an online option result in significant reductions in COeq emissions when compared to on-site only conferences. The selected European locations of these conferences enable more delegates to choose alternative forms of transportation instead of flying, such as trains, cars or buses, and consequently lead to significantly lower COeq emissions.

DISCUSSION

The principal avenues for curbing travel-related emissions while maintaining on-site attendance are the provision of hybrid conferences with enhanced online participation and the optimisation of venue locations.
