Eco-districts in France:What tools to ensure goals achievement?

Globally,to build cities and communities more inclusive,safe,resilient and sustainable is one of the most important sustainable development goals.Eco-districts in cities emerged as an answer to current global environmental concerns and have been developed in France since the 1990s.The objective of this work is to gather operational feedback from sustainable neighborhood projects owners to better understand the key barriers of such projects and how to overcome them.A case study of the eco-district Les Tanneries,Lingolsheim showed that the carbon footprint of each inhabitant annually amounted to 4 tons CO2 equivalent,more than half of the French average.Rooms for improvements were clearly identified regarding transports and food carbon footprint.Indicators for energy consumption,social diversity and density reached the level of the eco-districts average.A governance review pointed out some superior practices such as the formalization of a specification requirements handbook,a competition between project management teams,and the use of neighborhood sustainability assessment tools to measure and track changes in performance.The validated tools and obtained results can be useful in building sustainable cities and even China’s ecological civilization.
