“…Stemming the syndrome of mega-events (Müller, 2015) characterized by stronger local resistance and the withdrawals of candidate cities (Boston, Budapest, Rome, Hamburg, Munich), the notion of heritage and sustainability has become a key ambition in the new Agenda 2020 set up by the International Olympic Committee (Zembri and Engrand-Linder, 2023). For the economic model to bring gold back to host cities (Leeds, 2020), the patrimonial assets produced under the umbrella of the OPG in the tangible sphere of sports facilities and urban regeneration, what is hereinafter named heritage (Gammon and Ramshaw, 2015), should bring long-term positive effects to the inhabitants in the intangible sphere of economic, health, sports practices, environment, and inequality reduction, what is hereinafter named legacies (Rudan, 2023). In the difficult context of converging economic and environmental crises, Paris 2024 takes up the challenge of regenerating OPG to put it on a sustainable path by sharply reducing costs, eradicating the white elephant risk, and ensuring a neutral environmental impact on the local city while offering the same emotional magic coupled with its leverage effect of urban regeneration for disadvantaged neighbourhoods.…”
