One of the social problems on Yazd is the environment and if this problem cannot be controlled, it becomes a crisis and decreases the outcomes of developmental benefits. This problem is mainly caused by industrial development, geographical, climatic conditions, and dehydration. This paper focuses on the socio-cultural namely cultural capital, religiosity, life style and mass media use with environmental behaviors among citizens in Yazd. This is survey research and the population consisted of citizen in Yazd for whom 384 individuals were selected through random cluster sampling. Data collection technique was a questionnaire that has a suitable validity and reliability. The results showed that the environment factor was significantly related to cultural capital and lifestyle. There is a significant difference between men and women in environmental behaviors, too. However, age, marital status, mass media use, religiosity, education and environmental behaviors do not have a significant relationship. The results of regression analysis showed that the adjusted coefficient of determination for all the independent variables was equal to 0.278, meaning that all these variables could explain approximately 28 percent of the variation of the dependent variable (environmental factors).
