French-speaking webinar co-organized by IDDRI and Leonard Logo de Leonard

While several recent scenarios explore different carbon neutrality pathways for France, debates on what this really means for society are limited or even caricatured. However, as expressed collectively in our recent blog post, the scale of the transition means that the issue is as much social as it is technical, and there is an urgent need to better understand how it must be taken into account, and how it should be explored and debated.

One aspect of the possible social changes associated with the transition always attracts particular attention: the importance of sufficiency. This idea can be frightening or seem contrary to progress. However, when examined more closely in the context of these scenarios, the impression is quite different, since the analysis of the proposed changes to consumption, travelling, eating, etc., enable the implications to be better understood. Such analysis also highlights the fact that sufficiency is above all a matter of collective organization, and not only an additional responsibility to be shouldered by individuals. 

The objective of this webinar was to avoid thinking along the lines of being “for or against sufficiency” in order to discuss the changes involved in different ways, to look at the benefits and also the drawbacks, the way it is already being implemented by a diversity of actors, for what reasons and how. It was also to think about the social dimension of the transition, going far beyond the issue of sufficiency.
