How are the Games' carbon output calculated?

Paris 2024 has set itself the target of dividing the Games' carbon emissions in half compared to previous editions, using the widest possible scope (scope 3), which includes indirect emissions such as spectator travel.

For the calculation, the CO2 emissions of each of the products and services linked to the event are added together, using the "emission factors" in the ADEME Carbon Base.

Over 2,000 indicators, such as the breakdown of tickets sold by country or the quantities of IT equipment required, are regularly updated as the project progresses.

The final carbon footprint of the Games will be known and published by Paris 2024 after the event, thanks to the integration of data including spectator origin and modes of transport.
