The Legacy and Sustainability plan for the Paris 2024 Olympic and Paralympic Games — 20 Deployed in 2020 based on the “old” Games concept (for all venues apart from Tahiti), the initial expertise phase of this method/ action highlighted relatively low impacts and identified several opportunities to increase the positive impact of the Games. Almost all of the biodiversity at these venues that could be improved by the Games is “everyday” biodiversity. Exceptionally, less commonplace biodiversity was subject to rigorous specialist expertise and the appropriate regulatory files. At this point in time, we can confirm that: • most venues are located in ecosystems transformed as a result of old or recent land take; • the organisation of the Games requires few new structures and involves no overall net consumption of natural areas, woodlands or farmlands; • the developments in the villages will help improve these environments; • the impacts of temporary venues are relatively low and are offset. Following the initial expertise phase of this method/action (which excluded football venues and Tahiti), the impacts highlighted are relatively low and several opportunities to increase the positive impact of these venues have been identified. The pared-back approach to the Games requires few new structures for permanent venues overall and involves no net consumption of natural areas, woodlands or farmlands. Furthermore, the developments in the two villages will help improve damaged environments. All temporary venues are located in ecosystems transformed as a result of old or more recent land take.
