Résumé
A growing portion of scientists realized the need to not only alert about climate change, but also change their professional practices. A range of tools have emerged to promote more sustainable activities, yet many scientists struggle to go beyond simple awareness-raising to create concrete transition actions. This study proposed the use of a new game-based transition support system called " Ma Terre en 180 Minutes ", which is, to our knowledge, the first tool developed by and for the academic community. It has been designed to build scenarios of greenhouse gases (GHG) emissions reduction in the academic community, and present its deployment during the year 2021, including six hundred participants from 9 countries and 50 cities.
