In the seven years since Paris won the right to host the 2024 Olympic Games, several key promises made by the organising committee have remained unfulfilled. Many people feel that the ticket prices are too high, while parents complain that having to buy tickets for babies is at odds with the "People's Games." Organisers say the cost of tickets is comparable to London 2012.

The Paris 2024 Olympic Games opening ceremony on the Seine was initially planned for 600,000 spectators, including 100,000 ticket holders. Due to security reasons, attendance has been capped at 222,000, maintaining 100,000 paid ticket slots.

There has been a shift in philosophy as well. Initially, spectators were to register via lottery; now, all attendees will be directly invited by public administrations and the organising committee.

The French government's slogan, "The Games finance the Games," will not be realised, given the significant involvement of private funding and the fact that the various French public administrations have already allocated over 2.4 billion euros ($2.65 billion) for infrastructure, urban projects and the anti-doping laboratory, among other initiatives.

Macron reiterated that "there will be no Games tax", although much of the spending will come from public funds. Pierre Moscovici, President of the Court of Auditors, recently predicted that final the public investment could amount to "3,000 to 5,000 million euros." The true extent of public spending will be known after Paris 2024.

"All ticket holders would have access to free travel on the entire public transport network in the Paris region on the day of the competition," promised the bid dossier, but in the end this will not be implemented as originally stated.

In December 2022, the Paris Region Transport Authority, seeking to generate extra revenue, announced special prices for the Games: a single metro ticket for 4 euros, almost double the normal price, citing an expected 15% increase in traffic for the event.

Water polo, artistic swimming and diving will take place at the OAC, while swimming, one of the main sports at the Games, will be held at the La Défense arena on the other side of the capital.

The environmental impact is another issue that needs to be addressed. Initial plans called for a "positive" environmental impact by offsetting CO2 emissions, but this idea was later dropped. Critics, including experts, had raised concerns about the original concept, arguing that it gave the false impression that the event would have no environmental impact.

The organisation's current target is to reduce CO2 emissions by 50%. These emissions are divided into thirds: transport, infrastructure construction, and activities directly linked to the Games, such as accommodation and catering.
