By the end of 2019, the City of Paris initiated a process of mobilising cultural actors as part of its circular economy plan, in order to assess and promote a transition towards circular economy models in the cultural sector, based on its specificities, needs and the experiences of peers. This resulted in a first booklet of 9 toolboxes published on Paris.fr. In 2021, the City of Paris, in partnership with COAL and Les Augures, is continuing this collaborative work by exploring new thematic fields through two cycles of workshops around digital sobriety and materials, which will complement the tools already available.
