Affiliated with UNIL and EPFL, the Center for Climate Impact and Action (CLIMACT) was officially launched in June 2021. The center's main objective is to promote climate change mitigation and adaptation solutions through a collaborative and interdisciplinary approach. By working with various pillars of society such as media, politicians, and industry leaders, CLIMACT aims to bridge the gap between science and society. Through increased exchange and collaboration, we can accelerate a transformation towards a sustainable and inclusive future.

CLIMACT's unique approach to tackling climate change aims to be both innovative and inspiring. Our inter-institutional and interdisciplinary approach fosters a sense of community and encourages individuals from all walks of life to come together and work towards a common goal. By promoting awareness and facilitating discussions, CLIMACT is playing a vital role in creating a more sustainable future.

Media coverage of climate change research does not inspire action

Media coverage of scientific advances on climate issues does not activate the mechanisms known in psychology to trigger action in individuals and groups. This is the conclusion of a study conducted by social scientists and geoscientists from the University of Lausanne (UNIL - Switzerland).
