Abstract: This article has as object of study the repercussions of the dimension of the Human Right to Peace in Brazil after the decision of the Supreme Federal Court on Declaratory Action of Unconstitutionality No. 3,540, which recognized the rights of a brand-new dimension between economic and environmental aspects. The research method used was inductive, with bibliographic, jurisprudential, documentary, and normative investigation. The consequences of the pluralities of rights and people make the recognition of the Human Right to Peace in Brazil expose the advances and challenges regarding the applicability of sustainable intergenerational legal certainty. The result permeates the moral blindness of global actors, their modus vivendi and modus operandi in risk societies. Pointing out better efforts regarding Brazil's constitutional objectives and foundations in the face of the 2030 Agenda offers perspectives on understanding a complex of crises in which this right involves, giving prospects for an asymmetry to sustainability. Keywords: Peace. Risk and Sustainability. Intergenerational Legal Certainty. Development and Democracy.
