The current ecologic crisis challenges Western economic, social and political organisation. Nowadays neoliberal policies have become hegemonic but do not seem to be able to implement successful measures. The author proposes the main arguments of a critical study carried out through Lacanian Discourse Analysis on three environmental policy documents. This highlighted the role of «sustainable development» as ideological fantasy: one that obscures systemic contradictions in order to perpetuate them.
