June 2021 - Environmental sovereignty: portrait of our decision-makers. Last note written by our partner Sylvain Pelletreau with Henri de Grossouvre and published by the Institut Sapiens and the Cercle Colbert.
By advocating a broader and more structural vision of environmental protection, the Institut Sapiens and the Cercle Colbert are promoting the notion of environmental sovereignty.
In order to understand the issues, it is necessary to draw a portrait of the actors in the environment. This is how this note questions the role of the strategic state, the place of local authorities and the action of private actors. Beyond the observations, the authors wished to formulate proposals in order to embody the reflection carried by the note: creation of local directives, contractualization of relations between the State and local authorities and the emergence of a true principle of subsidiarity are so many proposals aiming to give true letters of nobility to the protection of the environment.
