The assessment of environmental impacts, it consists in the use of techniques and methodologies that aim to mitigate direct impacts to environment and to society. The present work comes to present the study of AIA´s evolution in Brazil and in the world, presenting their respectives aplication methods, identifying the positive and negative aspects of them. The methodology developed at work was a literature review, being this a systematic review, where research is based on a study of key techniques and history, providing the quality needed for future decision making. It has been found that each method itself has its qualities, and some have certain deficiencies, which can be corrected through the combination of methods, although this theme is still conservative for combined use of methods. The emergence of mathematical models has obtained certain advances, allowing for predictions that can help professionals during the elaboration of the EIA.
