The formulation of governmental policies, plans and programs has been conceived quite disconnectedly, without the necessary social participation and previous assessment of its impacts on the environment and people health. How do the assessment tools for public politics impact would contribute for the integration of those policies concerning sustainability? The work started as from this question, with the hypothesis stating that the public management for the sustainability assumes the integration of each field policies, at a strategy level, which passes beyond the policy impacts assessment. The public administration regarding sustainability, in this research, is relative to the process of public policies formulation and implementation, evaluating the aims of social, environmental, and economical sustainability. It also takes into consideration the cultural and institutional context where it belongs, as a way of turning the principles of precaution and the efficiency, operational, in the public administration. The objectives were to analyze the evaluation tools for policies, plans and programs (PPPs), as well as the Health Impact Assessment (HIA), which has a preventive character, and discuss how these evaluations can contribute to the integration and efficiency of field public policies. This research has been developed as a case study, and it analyzed the potential impacts assessment of the forest policy of Mato Grosso State, in groups of people, using the EPHIA methodology. As a result, the Health Impact Assessment Report indicated some institutional and administrative recommendations to improve the State management and the Forest Policy law, trying to minimize the health inequalities. The analysis concerning this assessment contribution identified the impact network of governmental policies, one on the others, as well as some points of sector disarticulation. The subsidies arising from the HIA allowed the ones who make the decisions to go forward in the definition of objective negotiation processes and in the integration of sector policies, transpolicity, aiming at the sustainable development.
