Environmental NGOs have been stablished due to society needs and raising public awareness and knowledge about environmental issues is the main role of NGOs. These organizations play an important role in achieving the goals of protecting the environment, reducing pollution and recovering environmental damages.

Content validity was confirmed by experts and its reliability Obtained based on Cronbach's alpha α=%88. Data analysis is done by using SPSS 21 and Smart-PLS software. In descriptive statistics mean, standard deviation and coefficient of variation and in inference statistics, structural modeling based on partial least squares approach were used.According to Table 1, the independent variable (environmental attitude), has the most effect on the of mediator variable (environmental intention) and also the most impact on the dependent variable (environmental behavior), and then environmental knowledge is most effective. Environmental intention as mediator variable is explained 59/6 percent of the variance of the environmental behavior between environmental NGOs members in Tehran Province.
