Abstract: eva‎luating environmental risks in the oil and gas industry is essential to prevent irreparable damage to the environment. Using traditional methods for prioritizing environmental risks does not achieve high-reliable result. Therefore, the aim of this study to minimize the limitations of traditional method, using of a high-reliable method for Kurdistan risk assessment. The investigated method includes fuzzy logic. First, the risk assessment will be done in the traditional way, then we will compare with the fuzzy method. Then, at the end of the fuzzy logic, they can show the real risk score related to the risks of each unit. According to this research, fuzzy logic can be a suitable alternative to the traditional risk assessment method (HAZID) when the result need to be expressed more accurately. Also, the fuzzy system can assign a number from zero to one to each of the risks, as a result, the problem of risk prioritization will be done. According to the result obtained from the 138 risks identified by the Hazid method, 46 of them have environmental risks, 72 have legal requirements and 20 of them need to be corrected. and the result of input and output fuzzification show that out of 46 environmental risks identified in the petrochemical complex the highest fuzzy priority number is related to hydrocarbon gases with a risk score of (0.75) and the lowest fuzzy priority number is related to hydraulic oils with a fuzzy score of (0.21). Keywords: Risk Assessment, Environment, Fuzzy Logic, Kurdistan Petrochemical, HAZID.
