In this article I have analyzed the national legislation that regulates the environmental impact assessment but also the attributions of the public authorities related to this topic. By researching the results obtained during the implementation of the legislation in this field, we can deduce that the existence of the legal framework does not fully guarantee the successful execution of a procedure, and in this case the implementation of environmental impact assessment. Although, the legislation of the Republic of Moldova regulates this process, in practice very few projects, whether public or private, are subject to environmental impact assessment. At the end of the article I have proposed some solutions to improve the performance of this large procedure.
