About the Climate Change & Sustainability Challenges

3 thematics will be tackled during this expedition:

1. The climate emergency for cities is adaptation and mitigation of extreme temperatures
   According to Jean-Marc Jancovici (The Shift project), finding a solution to adaptation would require a new Covid… What other approach can we propose to achieve this?
   What sustainable measures can we put in place without creating inequalities? Will cities have the means to adapt and radically mitigate their impact while ensuring strong social acceptance?
   One of the issues identified is the difference in pace: the need for rapid action versus social acceptance, which takes time. How can we increase the speed of public acceptance in order to change our cities (structuring according to cities and generations)?
2. Sobriety, as defined by the IPCC, is a set of policies, measures and everyday practices that avoid demands on energy, materials, goods and land, while ensuring the well-being of all humans within planetary limits. In other words, it is a question of questioning real needs and adapting the response in order to consume less energy or raw materials, and to limit greenhouse gas emissions and environmental impacts. Sobriety can concern all sectors: food, transport, housing, consumption of goods and services. Acording to the IPCC, sobriety must be at the heart of structural and collective changes, as well as individual changes.
3. Circular economy and waste management at the scale of cities
   We generate so much waste that its collection, treatment, recovery and disposal have become an industry in itself. These activities together are called waste management. Waste may sometimes be avoided through waste prevention and the circular use of resources.
   Together, waste management and circular economy strategies aim to reduce or minimise both resource use and waste generation, as well as their impacts on the environment and human health.
