This paper tells the recent history of CO2 chemistry through the contributions from members of CIRCC to its birth and growth. Starting with the first transition metal complex bearing CO2 as a ligand synthesized in 1975 by the Aresta Group in Bari, the mode of bonding and the reactivity of coordinated CO2 are discussed. The early applications in chemo‐thermal, electrolytic, and biotechnological processes, and the use of SC‐CO2 as solvent and reagent are fields in which CIRCC partners have made pioneering contributions and continue to provide essential inputs. The paper is closed by highlighting key issues and challenges at stake, from capture to large‐scale conversion, investment infrastructure, progressive policies and standardized regulations needed to advocate carbon recycling as a pillar of future innovation in energy and chemical industries. CIRCC has been the nest of modern CO2 chemistry and the place where CO2 has always been considered a "resource" rather than a "waste". [ABSTRACT FROM AUTHOR]
