As the two-year anniversary of the Paris 2024 Olympic and Paralympic Games approaches, organizers are releasing final reports on the event's environmental and social legacy. The Paris 2024 Organizing Committee has stated that the Games achieved their goal of halving carbon emissions compared to previous editions, largely through the use of 95% existing or temporary venues.
According to verified reports, the event's carbon footprint was calculated at approximately 1.5 million tonnes of CO2 equivalent. Key strategies included relying on public transport, utilizing renewable energy, and avoiding new permanent construction for most sports. The Athletes' Village has since been converted into housing and offices, a transition that was completed in late 2025.
However, legacy assessments are not uniformly positive. Several watchdog groups and academic studies point to budget overruns, with final costs exceeding initial estimates by billions of euros. Furthermore, some community organizations in Seine-Saint-Denis and other host areas report that promised long-term social and economic benefits, such as job creation and improved local infrastructure, have been slower to materialize than anticipated.
The International Olympic Committee has cited Paris 2024 as a model for future host cities aiming for sustainability. Yet, the mixed reviews underscore the ongoing challenge of balancing global sporting spectacle with tangible, equitable local legacy, a debate that continues as planning begins for the Los Angeles 2028 Games.
