The retail plays an important role in the Parisian economy and in the development of a low-carbon territory. Merchants represent a relay to promote more sustainable behaviors among their customers. Since 2017, the City supports the action of the Club Génération Responsable and participates in this network of companies involved in sustainable development. The City is particularly attentive to the implementation of a Responsible Point of Sale label that will promote the mobilization of teams on the territory to promote the commitment of the brand and inform customers on more sustainable practices.
