The problem of the research was manifested in the weakness in understanding the correct guidelines that must be followed in order to obtain and maintain the standard. The purpose of this research was to give a general picture of what is behind ISO14001:2015 and how it is possible to create a comprehensive base for understanding its application by seeking the gap between the actually achieved reality, standards requirements, and the diagnosis of their causes in the Medline Oil Company/ A field east of Baghdad by using the checklist and a number of statistical analysis methods (arithmetic mean, weights and percentages). The research reached a number of results; the most important of which is the existence of a gap in the application of the standard at a rate of (47.03%) resulting from a weakness in the application of most of the standard’s clauses in the company and lack of interest in the programs related to the treatment and reduction of environmental impacts.
