This research was out with the aim of analyzing the context for ICT development among environmental organizations in Ilam Province. The statistical population of this research was 20,000 individuals as members of environmental organizations, of whom 376 individuals were selected using Cochran's formula and studied through proportional stratified random sampling and questionnaire. The reliability of the questionnaire was assessed using Cronbach's alpha and to ensure its content validity, the panel of subject experts was used (α= 0.93). Data analysis was implemented using SPSSv22 statistical software. The results of exploratory factor analysis showed that infrastructural, economic, educational, technical-advisory and supportive factors were the main fields of ICT technology development in the target sample. The results of the regression analysis also showed that infrastructural, supportive and technical-advisory factors entered the regression equation in the first to third steps, respectively, and had the greatest effect in explaining the variance of the dependent variable "technology development".

Nowadays, the world has seen tremendous progress in the penetration of information and communication technology in individual and social life in countries worldwide, regardless of income level. While the increasing penetration of information and communication technology in economic, social, and energy dimensions creates exciting challenges and opportunities, examining its role in reducing or increasing CO2 emissions is essential. Therefore, the main goal of this research is to investigate the role of information and communication technology on the environmental quality of selected oil-exporting countries. The difference between this research and previous studies is that to investigate the impact of ICT on CO2 emissions, it uses a composite index of information and communication technology based on the principal component method (PCA), unlike previous studies that used only one dimension (for example, the Internet penetration rate). In addition to investigating the relationship between ICT and the environment, the study examines the existence of the Kuznets environmental curve and the relationship between foreign trade and the carbon dioxide index. The model estimation of the effect of information and communication technology on the environmental quality of selected oil-exporting countries, including Iran, from 2009 to 2019 has been carried out using the generalized method of moments. The estimation results indicate an inverse U relationship between information and communication technology and carbon dioxide emissions. Also, the results confirm the Kuznets curve hypothesis in the studied countries. According to the study, foreign trade has a positive and significant impact on CO2 emissions.

The emergence of the industrial revolution today has put the world on the verge of facing environmental crises, which is one of the most fundamental global problems, and facing it as a collective effort requires creating an environmental attitude in society. One of the areas that are heavily influenced by social media is the environment. The existence of virtual media acts as a catalyst that promotes environmental goals and social network users, especially an increasing number of them are young generations, and online activities are part of their daily lives. As the main custodians of environmental protection, it has entered this cycle.The purpose of this study was to investigate the role of information and social participation of social media on environmental learning and environmental awareness.

This study was conducted with a descriptive method of correlation and relying on the structural equation model. Also, this study was applied in terms of purpose. The statistical population of this study included all users active in social networks related to environmental issues, and according to the random sampling method, 230 people were selected as a statistical sample. The tool for data collection was a researcher-made questionnaire including social media capabilities and dimensions of information and social participation and learning and environmental awareness, which was used after confirming construct validity and reliability through Cronbach's alpha coefficient. The analysis, test of the presented model and study hypotheses were done using the structural equation method.

The findings of this study showed the positive effects of information and social participation of social media tools on learning environmental issues and environmental awareness among social network users. Also, in this study, the role of environmental learning on raising awareness of environmental issues was also confirmed.

According to the results of this study, organizations and institutions active in preserving the environment should pay attention to the role of social media in order to educate and promote environmental culture.

The purpose of the current research is to build and validate the model of the smart government with an environmental approach. This research is practical in terms of purpose and survey type in terms of strategy.

Finally, the model of the smart government with an environmental approach is presented with an interpretative structural method with the help of Micmac software in 12 levels.

Effective protection of the environment and optimal use of natural resources is one of the most important pillars of sustainable development. Green productivity is a strategy to increase environmental productivity and performance in order to social and economic development. The Information and Communication Technology (ICT) revolution has severely affected all countries in terms of economic, social, political, cultural aspects as well as security, employment, health, the environment, and many other macro variables; so that, the technology has become the main driving force of the world's economy and sustainable development in today's world. According to the importance and the impact of Foreign Direct Investment and Information and Communication Technology on green productivity, this paper uses the Johansen-Joselius coherent test of the relationship between Foreign Direct Investment and Information and Communication Technology and the Green Productivity Index in Iran.

The effect of Information and Communication Technology and Foreign Direct Investment on green productivity has been investigated in Iran using the Johansen-Joselius coherent test during the period of 1980-2013.

According to the research findings, the Information and Communication Technology and Foreign Direct Investment have a positive and significant and a negative and significant effect of on the Green Productivity Index in Iran, respectively. Also, the vector error correction model shows that the adjustment process is slowing towards the equilibrium.

According to the obtained results, and considering the negative and significant effect of Foreign Direct Investment on green productivity, which could be as a result of increased pollution, it is suggested that is possible to provide a ground to improve green productivity by adopting policies to reduce the destructive effects of Foreign Direct Investment, including the replacement of green energy.It is also recommended that environmental regulations and standards be imposed upon the entry of Foreign Direct Investment which could be done with less environmental pollution. The effect of Information and Communication Technology index on Green Productivity Index is positive and significant in Iran. Therefore, it can be surely said that the use of Information and Communication Technology, as a solution for green productivity institutionalization is essential for implementing the continuous and effective process of green productivity improvement. It is also suggested to determine criteria, for the development and implementation of the green productivity concept, that fully cover the qualitative patterns of economic growth and development.

Due to the inadequate design and use of buildings, a large amount of energy is wasted on these buildings. The purpose of this study was to investigate the motivational factors in green building construction and operation. The statistical population of this study was the builders and users of apartments in urban areas of Guilan province during the last 5 years between 2013 and 2017. The present study is a descriptive and correlational research based on applied purpose and in terms of data collection. Structural equation modeling was used to collect field data, questionnaire data collection and data analysis. After descriptive analysis of the variables to test the hypotheses, the research hypotheses were tested by using multiple linear regression method and comments on whether or not the statistical hypotheses were accepted. The results showed that quality of life, quality and price had a direct impact on the construction and operation of green buildings in both owners and developers. On the other hand, the findings showed that environmental awareness and information and knowledge had a direct impact on the construction and operation of green buildings in the owner group but did not affect the builder group.

The total impact of Information and Communication Technology (ICT) on energy consumption is unclear. In this regard the main objective of this paper is to analysis and comparative the impact of ICT Development Index (IDI) on energy consumption in the developing and developed selected countries during the period 2007-2013.
For this purpose, the short run and long run elasticities between the variables of the model estimated and analyzed using a system generalized method of moments (GMM-SYS).
The results show that a one percent expansion of ICT, in the short and long term, respectively, increased the energy consumption per capita in developing selected countries amount 0.01 and 0.12 percent and reduced the energy consumption per capita in developed selected countries amount 0.03 and 0.09 percent.
Development of ICT, increased the energy consumption in developing countries and reduced the energy consumption in developed countries.

Urban population in Iran is increasing. It is supposed to intensify the usage of raw materials, vehicles, energy and etc., and consequently lead to the environmental pollution which is a barrier to sustainable development realization. Therefore, along with the process of urban development settling down, its environmental consequences should be managed as well. Meanwhile information and communication technology (ICT) application such as E- Government, E-Commerce and etc., could play a vital role in reducing the subsequent negative impacts on environment. This has been considered as the main theme of this study.
In this study, it is attempted to assess the impact of information and communication technology on Urban Sustainable Development process in Iran, using provincial data through Panel Data technique. The hypothesis was tested separately for developed and less developed provinces of Iran.
Findings: The results imply that ICT had significant and positive impacts on improving the environment and achieving sustainable development (just) in developed provinces.
Seemingly, this attributed to the differences in degree of ICT penetration and institutionalization amoung developed and less developed provinces.

This study aims to explore the diffusion patterns of information based on ontology. Methodology was survey- descriptive. Data was collected by questionnaire. Population was the experts of department of environment (DOE), that 178 persons using systematic random sampling method. Findings showed that concepts of ontology, environmental impacts and pollution are the main information flowing in sections of DOE, and finally, general subject about environmental condition. Regarding the ontology of diffusion process and patterns, findings also revealed that one step and two steps patterns are used to transform environmental information, and among the network patterns, models of the vector with side branches, the network and the tree are applied to flow environmental information. About the ontology of knowledge objectives and methods, results also showed that respondents used internet web (email and search of information), workshop, news website, article and proceedings of conferences and seminars as methods and tools of local and global to obtain and diffuse environmental information. Finally, based on the results and in framework-driven ontology engineering processes, developing an environmental social web network was recommended to facilitate information flow for environmental protection.

In the past few years, the Information and Communication Technology (ICT) applications have been widely transformed human life. Based on theoretical principles, it seems that ICT through digitalizing of economic activities can improve environmental quality. This hypnosis is not verifiable simply and needs case studies researches. This article shed light on this point in a macro level, through cross-country approach.To do that we selected two separated groups of countries, which are: OECD countries as highly developed ones and some of the developing counties (including Iran) and developed a generic model and estimated it through Panel Data technique for 1990-2005. The results imply a significant but light observable impact of Information and Communication Technology on environment in developed countries. However, in developing countries it doesnt make sense significantly. It seems that developed countries would be able to achieve the maturity threshold of ICT application and consequently benefit from its capabilities to preserve the environment which developing countries have long way to achieve this.
