The 2030 Winter Olympics, to be held in the Alps, are being planned by an organization called Solideo Alpes 2030. This event will take place in several regions, including parts of France such as Haute-Savoie, Savoie, Briançonnais, and the Métropole de Lyon, as well as the Netherlands, where speed skating will be held. The organizers are focusing on sustainability and plan to use about 93% of existing or temporary facilities. This is a significant increase compared to previous Winter Olympics, which typically used only 43% of existing structures. The goal is to reduce the environmental impact of the event and align with the sustainability efforts seen in the Paris 2024 Games. One of the key locations for the 2030 Winter Olympics is Saint-Jean-de-Sixt, where a new Olympic Village is being built on the site of an old, unused vacation camp. This village will have over 14,000 square meters of space and will host nearly 1,000 athletes. After the Games, it will be converted into a residential area with 75 housing units, including some social housing for local residents. Another important site is Courchevel, where existing ski jumps will be renovated at a cost of 60 to 70 million euros. The design of the Olympic Village in Saint-Jean-de-Sixt is being handled by Petitdidier Prioux (PPX) and Arcane Architects, who aim to blend traditional Alpine architecture with modern sustainable practices. Despite these ambitious plans, the project faces several challenges. Tight deadlines and budget constraints are major concerns, as is the potential environmental impact of using artificial snow and the strain on water resources. The choice of Bouygues Immobilier as the main contractor has also raised questions about the quality of the architecture, especially after past issues with the design of the Paris 2024 Village. Additionally, the organization has experienced leadership changes, including the resignation of the General Director in February 2026, which was attributed to disagreements with the president. The organizers of the 2030 Winter Olympics aim to leave a lasting legacy by transforming Olympic sites into sustainable communities. They hope that the infrastructure built for the Games will be used long after the event, benefiting local populations and the environment. While the project has faced obstacles, the focus on sustainability and reuse of existing facilities reflects a broader shift in how major sporting events are planned and executed.
