Paris has developed an extensive plan to promote sustainable transportation. The city’s well-established public transport network has been enhanced, and athletes and spectators were encouraged to use bicycles and electric vehicles. The Olympic Village is designed to be car-free, further reducing emissions. Additionally, the Olympic fleet has been reduced by 37% compared to the previous games (How the 2024 Paris Olympics fast-tracked decarbonization). Transport to the Games focuses on accessibility and sustainability:

Public Transport: Enhancing the city’s public transport network, with 80% of the venues located within a 10 km radius of the Olympic Village (Will the Paris 2024 Olympics be the Greenest Ever?).

Green Vehicles: Using electric, hybrid, and hydrogen-powered vehicles to reduce emissions is encouraged.

Extensive Cycling Infrastructure: Paris has expanded over 400 km of cycling lanes linking all competition venues, promoting cycling as a sustainable mode of transportation.

An ambitious waste management program aims to achieve a 70% recycling rate during the games (IOC). Single-use plastics are banned, and extensive recycling and composting facilities were set up across the venues. Nearly 11,000 seats are made from recycled plastic bottles and caps (Paris Olympics to give waste a second life)

A cornerstone of the Paris 2024 sustainability strategy is the extensive use of existing and temporary venues, minimizing new construction. Approximately 95% of the venues are considered to be pre-existing or temporary, aligning with the IOC's sustainability recommendations (IOC). Key sustainable features include the Aquatics Centre and the Paris 2024 Olympic Village. Both venues are located in the northeastern suburban areas of Paris which are investment lacking locations in the city.

Environmental Cleanup: Paris undertook a major effort to clean the River Seine to ensure it met safety standards for the 2024 Olympics, investing €1.4 billion in projects like the construction of an underground rainwater storage tank and upgrades to water treatment facilities (apnews.com). This cleanup aimed to address pollution caused by overflow from the city's aging sewage system during heavy rains. The Seine was chosen to host various Olympic events, including the triathlon and marathon swimming, with the goal of showcasing environmental commitment and leveraging the Games to promote urban regeneration and sustainability.

During the Olympics, the men's triathlon swimming leg was delayed due to elevated E. coli levels in the River Seine, caused by heavy rains leading to sewage overflow. Despite significant investments to improve water quality, water quality issues persisted. Although the triathlon event was postponed, contingency plans, such as alternative venues and reserve days, were implemented. Ultimately, the water quality met safety standards, allowing the triathlon events to proceed.

The Games operate entirely on 100% locally sourced renewable energy from France (Wind & Solar), transitioning seamlessly away from temporary diesel generators (Choosing renewable energy). Major venues like the Aquatics Centre and the Olympic Village are outfitted with solar panels, while geothermal cooling systems enhance their energy efficiency. The Athletes' village, set to become social housing post-Olympics, incorporates sustainable features such as natural cooling systems, despite the initial lack of built-in air conditioning. At the Aquatics Centre, the building is designed to optimize energy consumption for both the Games and future use. The concave roof shape reduces the volume of air needing heating by 30%, while pool water is maintained at 28°C using heat recovered from a neighboring data center. Additionally, photovoltaic panels on the roof will supply approximately 20% of the building’s electricity needs.

The geothermal cooling system has fallen short of expectations, struggling to maintain optimal temperatures amidst the summer heat. As a result, many participating countries have resorted to bringing their own air conditioning units or renting them locally to ensure the comfort of their athletes and staff. The situation highlights the challenges of relying solely on sustainable solutions in large-scale events, underscoring the need for backup systems to address unforeseen climate conditions.

France is renowned for its rich, meat-centric cuisine, but Paris 2024 aims to reduce the carbon footprint of the 13 million meals expected to be served during the Olympic and Paralympic Games. The Food Vision initiative will double the amount of plant-based food compared to London 2012 and Rio 2016, with 80% of ingredients sourced from France, including all meat and dairy products. Efforts to limit food waste and reduce single-use plastics in catering by 50% aim to ensure each meal has a carbon footprint of 1 kg of CO₂, compared to the French average of 2.3 kg (IOC). Despite these efforts, catering is anticipated to account for only 1% of the Games' overall carbon footprint, and concerns remain about food waste and Coca-Cola's use of single-use plastic bottles, raising accusations of greenwashing.

Single use plastics banned for Olympics and Paralympics

Reduction, renting, and reusing are key elements of the Paris 2024 sustainability strategy. A circular economy approach is being implemented like fully recycled metal medals and re-using mattresses from the athletes' village. This helps to reduce new resource use and ensure the reuse of equipment and goods, with second lives secured for 90% of equipment and goods and prioritizing the renting of equipment from sports federations. The Aquatics Centre, predominantly constructed from carbon-storing timber, will be repurposed into a community venue after the games, contributing to a lasting legacy. 

Numerous athletes competing in the Paris 2024 Olympics are also sustainability advocates. They utilize their platforms to raise awareness about environmental issues and encourage eco-friendly lifestyles. Their dedication extends beyond competition, embodying a comprehensive approach to health and wellness.

The Paris 2024 Olympics underscore the unique potential of the Games to drive environmental awareness and sustainability practices worldwide. Despite existing challenges and criticisms, cities hosting the Olympics can leverage the event to spark significant environmental improvements and serve as role models for global sustainability efforts.
