The increase in population causes more urban areas to be built. Laws, norms, guidelines and deliberations govern the environmental licensing of an undertaking. The objective of this article is to demonstrate the procedure to carry out an environmental licensing using a process for a power generation plant and to monitor its process. A basic, qualitative and exploratory research was used with the purpose of making the problem familiar, trying to explain and clarify it. The use of instruments to clarify the lay client seems to have an effect. Visualization seems to be an attractive way of doing this. The execution of an environmental licensing goes through several stages and follows laws, norms, guidelines and deliberations that are not constant.

Some legislative changes may negatively influence the attempt to minimize the anthropic impact on natural areas.
