Paris Mayor Emmanuel Grégoire has unveiled a 400-million-euro climate change adaptation plan designed to enhance school infrastructure and public spaces to better manage the risks of future heatwaves. The initiative focuses on the massive acceleration of renovations for school buildings, especially in areas that experience extreme summer temperatures. The city has begun selecting schools for upgrades, taking into account factors such as declining student numbers and the age of the buildings. As part of the plan, Paris City Hall intends to install 100 sunshades in the most exposed streets starting next summer. These sunshades are expected to reduce the perceived temperature by 10 to 15 degrees. The city also plans to advance the opening of swimming in the Seine River and its canals as early as June 2027. Emergency work has already begun this summer in around 100 of the 620 schools in Paris. The city aims to provide cooled rooms in "100% of schools, nurseries and middle schools" by 2027. This includes equipping more than 360 institutions with solar protections and 130 with air circulators, as well as creating 245 "oasis courtyards" and 70 shaded or misted courtyards. Portable air conditioners used during the summer, which have been described as having "uneven quality," will be gradually replaced with cooling devices that "limit heat emissions." The plan also includes connecting to the Paris Coolness cold network, which currently cools buildings such as the Louvre and the Forum des Halles using water from the Seine or geothermal energy. The mayor stated the goal is to connect 300 facilities to the network by 2042. Opposition figures have criticized the plan, with ecologist Emile Meunier estimating the full thermal renovation of schools at 2.52 billion euros. Meunier, along with Sophia Chikirou from the LFI party, has filed a lawsuit with the administrative court to compel the City to produce a multi-year program. Meanwhile, Grégory Canal, co-president of the right-wing group Paris Liberté, noted that while the Paris executive justifies its more than 10 billion euros in debt in favor of climate adaptation, the accounts do not balance.
