Tamara Ben Ari is a researcher at INRAE, where for nearly 10 years she conducted research into the stability of global agricultural production and the effect of climate change on it. She co-founded Labos 1point5 (www.labos1point5.org) in 2019 with astrophysicist Olivier Berné (CNRS) to estimate, understand and reduce the carbon footprint of research. She then went on to create the Labos 1point5 research group (GDR), which she led for two years with a multidisciplinary team, and which is actively contributing to the emergence of the environmental footprint of research as a field of research in its own right, and whose spin-off into other sectors of activity and abroad is booming.
