In this article, we present the results of a qualitative survey based on semi-structured interviews administered to 60 citizens of the French-speaking part of Switzerland to determine their attitudes, behavior, and expectations concerning sustainable development. The study sheds light on what individ-uals think about the impact of their own behavior, their efforts in sustainable development, and the role they expect private companies and public author-ities to play in this area. On the one side, they are becoming aware of the growing power they can wield over private companies to force them to make substantial efforts and, above all, to prevent them from greenwashing. On the other side, they are also very clear about the role expected of public authorities. They don't rely solely on public authorities to establish a legal framework to govern and oversee private companies' carbon emissions. They also anticipate public services to establish a framework that encour-ages greater transparency in communication regarding this matter. This transparency will help consumers make more informed decisions aligned with environmental concerns and empower them to play an active role in driving change, rather than being passive observers. This is an expectation that they are also clearly expressing to better understand the impact of the digitalization efforts they are making individually and within their company.
