Land Use and Transportation Laws’ efficiency with regard to Air Pollution in Tehran Metropolitan Area

Air pollution is the major concern and challenge of Tehran urban areas’ management. Various rules, regulation, and laws had been codifiesd on this matter. In present research, the enforcement of laws and regulation concerning air pollution in the field of land-use and transportation is being addressed. The purpose of this article is to suggest an applicable (applied) framework embracing a descriptive-qualitative method. The following data had been extracted through documentary, libraries studies, and semi-structured interviews. Eventually, the role of each actor would be analyzed in Tehran urban area’s air pollution using the actuator network theory. The results show that the Department of environment, which is responsible for matters related to safeguarding the environment, has no main role in implementing the air pollution regulations as the main body responsible for the air’ quality control, and It has no topological connection with other organs, as well. The study of the feasibility of the reviewed laws and regulations illustrated that among 79 extracted substances, only 17.8% of those were fully completed. Moreover, 60% of laws have a single trustee and on the other hand, the rest of 40% is defined as a joint action between the systems. The 8 main actors have been recognized among the 20 actors who are the law’ trustee. These actors are responsible for doing 87 percent of all studied regulations.
