CLIMACT is a joint EPFL and UNIL Center whose mission is to promote systemic actions as well as interdisciplinary and inter-institutional research in the climate field.
CLIMACT (Center for Climate Action and Impact) is a joint center of EPFL (Ecole polytechnique fédérale de Lausanne) and UNIL (University of Lausanne), established to promote interdisciplinary and inter-institutional research and initiatives that address the challenges of climate change mitigation and adaptation.
Our mission? To pave the way for a sustainable future, by promoting interdisciplinary and inter-institutional research and implementing cutting-edge initiatives that address the social, scientific, and technological dimensions of climate change mitigation and adaptation.
By consolidating research and innovation activities related to climate change, CLIMACT aims to give them greater visibility and impact within the broader community. With a focus on collaboration and innovation, CLIMACT is taking important steps towards a more sustainable future.
Through our research and outreach activities, we hope to inspire and engage communities in the fight against climate change.
Together, we can make a difference!
CLIMACT launched its activities in June 2021, spearheaded by its executive director, Dr. Nicolas Tétreault, and guided by its two academic co-directors: Professor Samuel Jaccard from the Faculty of Geosciences and Environment (FGSE) at UNIL and Professor Michael Lehning from the School of Architecture, Civil and Environmental Engineering (ENAC) at EPFL. Professor Julia Steinberger (FGSE, UNIL) also served as CLIMACT's academic co-director for UNIL from June 2021 to April 2023.
In its short existence, CLIMACT has already provided direct funding for seventeen innovative projects and actively participated in countless others. Additionally, the centre's affiliated researchers have launched two major SWEET, one ERC and four ETH Joint Initiatives projects demonstrating their commitment to being at the forefront of climate change research and promoting a sustainable future for all.
