The aim of this research is to verify the effect of environmental regulations on environmental and economic performance through the establishment of a green supply chain with the mediating role of government support and private sector participation with a green innovation approach. The research is practical and descriptive in terms of objective and data selection. The statistical population of the study is experts and pundits available in the field of the supply chain in the industrial park of greater Tehran. 136 people were selected by the non-probabilistic sampling method. Research data are collected according to a standard questionnaire. All extracted data are analyzed using SmartPls statistical software with a variance-based structural equation approach. Statistical indicators such as Cronbach's alpha Composite Reliability, criterion validity and convergence validity of mean-variance, and Fornell and Larker divergence validity have been used to explain the validity of the published questionnaire. The results of the study show that environmental regulations affected the establishment of a green supply chain with the mediating role of government support and private and public partnerships 0.228 and 0.627, respectively, affecting environmental performance. The direct effect of establishing a green supply chain on economic performance in short-term and medium-long term performance were 0.769 and 0.653 respectively. The result of the study can be deployed in green supply chain management (GSCM) at manufacturing companies, especially are located in Tehran. Through the approach of environmental regulations, government support, and the participation of companies in the profitability of themselves, the growth rate can be observed in the economic performance of the country.

Nowadays, due to the growing process of global warming, increase of greenhouse gases and reduction of natural resources, environmental crises are more than ever before, therefore one of the topics that has attracted a lot of attention in educational systems is to present new attitudes of conservation. Environment is in education, which is considered one of the important tasks of the educational system and is applied in educational books. Considering the importance of the environment, the purpose of this research is to analyze the content of fourth grade textbooks based on the level of attention paid to green management components. The research method is descriptive and qualitative and quantitative content analysis, which analyzed the data using Shannon's entropy technique. The statistical population of the research includes social studies, Farsi and experimental science books of the fourth grade of elementary school, which due to the nature of the subject, sampling was not done and all the statistical population was examined. and the research tool in this research is a checklist and based on the report of the technical and research office of the "Green Management Steering Center", the indicators of green management in several main areas including energy management, water and wastewater management, benefit from renewable energy, waste management, pollution control Sound, transportation and the spread of culture and strengthening of social responsibilities in the field of environment, the selected books were studied according to these components. The obtained results showed that the highest coefficient of indicators related to green management for the fourth grade social studies course was for the index of energy management and use of renewable energy, respectively. For the Persian course, water and sewage management had an importance coefficient of 0.26, and for the experimental science course, water and sewage management, use of renewable energy, noise pollution control and transportation, energy management and promotion of culture and environment had an importance coefficient of was 0.17.
