Résumé
Despite increasing consumer awareness of environmental issues, a persistent gap remains between growing environmental concerns and only modest changes in consumption habits. This gap is further exacerbated by skepticism toward corporate actions and priorities regarding ecological transition, as well as by the perception of greenwashing strategies. Given the limitations of individual behavior, both from consumers and companies, the role of public authorities becomes central. This research investigates how consumers perceive regulatory frameworks imposed on companies concerning the eco-responsibility of their product and service offerings. Based on a qualitative study conducted with 36 consumers, it aims to better understand the interplay between public regulation, corporate engagement, and sustainable consumption behaviors. The perceived effectiveness of legal obligations compared to voluntary corporate initiatives, viewed from the consumer’s perspective, represents a strategic issue for both public policy and the marketing strategies of companies committed to ecological transition.
