today, with rapid advancement of industry and technology, many concerns about the adverse consequences threaten human life. The objective of this research is to investigate environmental education as an implement to reduce and evaluate the environmental consequences of petrochemical products based on the hierarchical analysis. The methodology was a survey of a statistical group involving 30 managers and experts in the petrochemical industry. The tool for the survey has consisted of a questionnaire with a pair scale-single response. In this model, the validity of the research was confirmed by the Delphi method and obtaining the opinion of experts in the field of occupational health and reliability of the questionnaire calculated by the inconsistency rate (less than 0.1). First, three criteria including environmental impact, destruction of the natural environment, impacts on individual health, and the most important harmful effects of each criterion were identified. Among the three main criteria, the most influential factor is the environmental impact criterion with a relative weight of 0.670. The criteria for the destruction of the natural environment and health effect of petrochemical workers with a relative weight of 0.260 and 0.699, respectively, are in the next priority. The water pollution parameter with a relative weight of 0.602 is the most important among the 5 sub-criteria. The parameter of effects on the biological environment with a relative weight of 0.373 among the 3 sub-criteria, and the parameter of the respiratory system with a relative weight of 0.417 among the 5 sub-criteria have the greatest effect, respectively
