Sustainable development Article published on 09 September 2021 , Updated on 07 October 2021

As part of the European Sustainable Development Week initiative, Université Paris-Saclay is organising Sustainable Development Weeks across its campuses, from 14 September to 8 October.

Throughout the 2020/2021 academic year, Université Paris-Saclay demonstrated its commitment to sustainable development with a range of different actions, including: the participatory approach, the creation of a Sustainable Development Charter, informative webinars on the future of the University’s Vallée campus and building management, but also partnerships with organisations and other universities by launching a series of webinars (Terre & Cité, the Santa Clara Valley Open Space Authority, The Nature Conservancy, EIT Climate-KIC, UC Davis).

The Sustainable Development Weeks (SDW) are an opportunity for students, staff and the general public to meet and talk about sustainable development issues. Once again this year, a whole host of events are being organised to raise awareness and take action for sustainable development. Exhibitions, webinars, second-hand clothes sales, World Clean Up Day and film screenings have all been planned over the four-week period.

Early October (date and time to be confirmed): Screening of the film “Alors, tu trouves ?”, followed by a debate. Camille, a young climatologist, has a series of contracts with the French Centre for Scientific Research. But understanding how the climate works and just drawing graphs foreseeing future catastrophes from behind her computer screen were no longer enough for her. She decides to get closer to the land and people, both far from and close to her research laboratory. Her journey takes her to China, Polynesia, Mali and Essonne (France), where her lab is located, and throughout Camille learns that the solutions for climate change already exist. Camille will have to make a personal, unexpected but logical decision. View the poster for the film here (in French).

7 October at 5 pm: Launch of the “Sustainable Campus” (2021/2022) at Université d’Evry (amphitheatre 300). With the participation of Jane Lecomte, Vice-President for Sustainable Development at Université Paris-Saclay.

The two speakers will attempt to answer these questions by analysing the conclusions from the latest IPCC report (Intergovernmental Panel on Climate Change) and the recent co-sponsored IPBES-IPCC workshop report (Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services). Both speakers will answer your questions on the topic. To attend, click here.
