As Paris successfully hosted the Olympic and Paralympic Games in 2024, SOLIDEO, the agency created to deliver the venues, placed the social and ecological legacy of the Games at the heart of the design process. The development of the new Olympic Village in La Seine-Saint-Denis became a leading example of sustainable design, demonstrating how rich biodiversity can thrive in dense urban areas.

Paris 2024 marked a new era for the Games—one that was more environmentally friendly and supportive. The sober Games concept relied 95% on existing or temporary equipment to limit pressure on habitats. A specific preservation strategy was implemented to assess and manage the Games’ impact across five sustainable pillars. Urban biodiversity played a central role, encompassing both remarkable and ordinary biodiversity—nature that was left untouched and nature that was integrated as much as possible. Paris 2024 went beyond preservation by identifying regeneration opportunities for the urban sites that served the Games.
