The increase in motor vehicles has greatly increased air pollution in the Tehran metropolis and turned it into a challenge. By analyzing transportation pollutants, low-carbon cities and sustainable development strategies for urban districts can be achieved. This study deals with the spatiotemporal analysis of pollutants and transportation accessibility in the urban districts of Tehran. The concentrations of CO and NO2 pollutants were extracted from the Sentinel-5P satellite using coding in the GEE environment. OSM data were used to calculate the accessibility of the 22 urban districts. Moran's global autocorrelation indicated a clustered spatial distribution pattern of pollutants. The high autocorrelation value equal to 0.94 for CO and NO2 pollutants indicated their cumulative state in the atmosphere. By performing LISA, most clusters of these pollutants were identified in the central districts and southern suburbs. The average accessibility indicator of the 22 districts was 24.82 km/km2. About half of Tehran's urban districts had a high density of road transport networks. These districts are located in CO and NO2 clusters owing to the high traffic volume of motor vehicles. The results of this study emphasize the factors that aggravate Tehran's air pollution, including the clustered pattern of pollutants in the atmosphere and dense transportation network in urban districts. By integrating air pollution analysis and accessibility estimations into urban planning frameworks, cities can strive to achieve long-term sustainability goals.

Environmental problems and the need to develop more sustainable cities are the focus of many smart city projects. So that, smart cities in many developed countries have focused on issues related to energy and sustainability. The purpose of this research is to measure the level of smartness of cities in the direction of sustainability in Chabahar city. The current research is applied in terms of the type and purpose of the research, and descriptive-analytical in terms of the data collection method. Library and field methods and questionnaires were used to collect the data. The statistical population of the research was 106,739 citizens of Chabahar city. The sample size is 335 people through Cochran's formula. The results showed that the smart city indicators in Chabahar city are in an unfavorable situation. Also, the smart economy criterion with a weight value of 0.279 is in the first place and has been chosen as the most important effective criterion of smartening cities in line with urban sustainability. The criterion of the smart government is ranked second with a weight of 0.217. The criterion of smart mobility is ranked third with a weight value of 0.195. The standard of intelligent life is ranked fourth with a weight of 0.162. The criterion of smart environment with a weight value of 0.101 is in the fifth place and finally the criterion of a smart citizen is in the sixth place with a weight value of 0.060.

In this paper, we present a comprehensive plan for transforming Tehran into a smart city by leveraging machine learning techniques while prioritizing sustainable development, balanced development, and resilience. The plan outlines the key components, including data collection, machine learning algorithms, and initiatives for sustainable and equitable development. We discuss the hardware and software requirements for implementing machine learning algorithms in a smart city context, along with examples of input and output data for various applications. Additionally, we highlight the importance of monitoring, evaluation, and iteration to ensure the effectiveness of smart city initiatives. By following this plan, Tehran can harness the power of machine learning to address urban challenges, improve quality of life, and foster long-term prosperity for its residents.

This study investigates the effects of environmental education on female and male students' knowledge level through visual mass media. The data gathered by researcher made questionnaire which the specialist calculated its reliability (0.77). To get the research aim researcher used semi experimental method using the pre-test and post-test method between experimental and control group. The sample of this study was 60 university students who were selected by simple randomly among 1450 students of Shahid Rajaee teacher training university that didn't pass any course about the environment. Then they were divided randomly to experimental (n = 30) and control (n = 30) groups. The experimental group was taught by using visual (film) mass media, while the control group didn't receive any education. The information processed and analyzed by independent t-test. Results showed that the visual mass media have a positive impact on environmental knowledge of the students. So it is recommended to use visual media productions (videos, clips, etc.) as a platform for delivering knowledge, information and education,  in environmental issues.

Education at all levels plays a very important role in achieving sustainable development. The main goals of education are to raise the level of knowledge, analysis and ethics in individuals and increase their sense of responsibility towards society. Chapter 36 of Workbook 21, entitled "Education Development and Raising Awareness," addresses the importance and role of education in sustainable development. Engineer training in the 21st century should be in line with the goals of sustainable development so that it can play a role in correcting the attitude of young engineers and applying these principles in their lives and specialized activities. One of the important tasks of universities is to provide a suitable platform for such education. In this regard, Amirkabir University of Technology, as one of the most important industrial universities in the country, is developing various strategies in this field. Establishment and strengthening of postgraduate courses in environmental engineering, presentation of new courses related to various fields of environment and sustainable development for all engineering students, change and modification of course topics and establishment of environmental research institute are among the most important of these strategies. As an example, a course called "Green Design" is envisaged in the curriculum in which students become familiar with the basics and principles of green attitude in design. Changing the attitude of engineering students from traditional design to green design (where the principles of sustainable development are considered by the designer) is one of the main goals of this course. The purpose of this paper is to examine the role and tasks of 21st century engineers and to explain the basic strategies of Amirkabir University of Technology in line with the goals of the Green University and sustainable development.
