The objective of this study is to contribute to raising the awareness of decision-makers regarding the use of the Strategic Environmental Assessment (SEA) instrument, when used in conjunction with the Blue Amazonia Management System (SISGaaz), if applied in governmental Plans, Programs and Projects (PPP), ensuring that environmental values can be considered in the decision-making process, along with technical, social and economic aspects, preventing and eliminating impacts and cumulative effects on the environment. This requires a political awareness of those involved and a tool to support decision makers in order to optimize the risks involved. Thus, the evolution of legislation in the context of environmental impact studies and the environmental licensing process, the national and international experiences, the benefits and the main limitations of this instrument were raised in the literature. On the other hand, SisGaaz presents itself as a Brazilian Navy program that can contribute, as a tool, to the evaluation of the strategic environmental impact in public PPPs of the environmental area, due not only to its holistic view, but mainly due to the great interactivity that the SisGaaz will allow among the different systems of the strategic plan in the governmental sectors in the country.
