The games are being described as the greenest in Olympic history, with Paris 2024 pledging to halve the event’s carbon footprint compared to the average of previous Summer Games.
Planning the “most sustainable” games will mean limiting emissions to around 1.75 million tonnes of CO2. Previous summer Olympics, which include Tokyo 2020, Rio 2016 and London 2012, have emitted an average of 3.5 million tonnes of CO2, the Paris 2024 Organising Committee says. Besting emissions from Tokyo’s games will be particularly remarkable as that event did not have spectators thanks to COVID-19 restrictions.
In addition to avoiding and reducing emissions, the Paris 2024 sustainability strategy will incorporate offsets, investing in environmental and social projects around the world.
Reuse and recycling at Paris 2024
Hosting the Olympics in the past has typically brought big spending on new venues. But 95% of Paris 2024 will be hosted in existing buildings or temporary infrastructure.
The Stade de France, which was originally built for the 1998 football World Cup, will host most events.
Only one new competition venue, the Aquatics Centre in Saint-Denis, is being built for the 2024 Olympic Games. It is solar-powered, uses natural bio-based building materials and is fitted out with recycled materials.
From renewable energy to recycled fishing nets
For biodiversity, rooftops have been built with enclosures and openings to house insects and birds. And almost 9,000 trees have been planted around the athletes’ village to attract different species.
The 2,800 Olympic apartments will be converted into homes after the games.
Sustainable travel and food choices at the 2024 Olympic Games
Why sustainable choices matter for the climate
Vegetarian diets and other low-carbon life choices, like sustainable travel, can make a difference when they’re adopted collectively by large numbers of people, the World Economic Forum says in its latest Global Risks Report 2024.
Collective efforts like these can alter market dynamics and “move the dial on climate change mitigation,” the Forum adds. Businesses making sustainable and ethical choices are also critical to driving improvements worldwide, while collective action can help to prepare the world for global risks.
By 2034, environmental risks make up four of the top five risks identified in the report.

Extreme weather events and a critical change to Earth systems – such as a climate tipping point in global warming – are the top two risks. Biodiversity loss and ecosystem collapse, and shortages in natural resources are also in the top four global risks.
“The actions of individual citizens, companies and countries – while perhaps insignificant on their own – can move the needle on global risk reduction if they reach a critical mass,” the Forum says.
