The FIR focused on the « new frontier » of integrating ESG into asset allocation, a subject that has been little discussed and documented to date. To this end, the FIR has launched a working group co-piloted by Helena Charrier, Deputy Group Sustainability at the Caisse des Dépôts and Jean-Philippe Desmartin, Director of Responsible Investment at Edmond de Rothschild Asset Management. The booklet resulting from this work aims to explore the motivations, methodological issues and academic challenges related to ESG-climate integration. Finally, the booklet includes a series of concrete research avenues intended for the academic community.
