Todays, the issue of environmental instability and destructive environmental behavior can leave many irreparable effects and damage on future ecosystems and the lives of future generations. Method: This study aimed to present an environmental model of sustainable development in the Iranian gas industry. The present study used a qualitative with grounded theory method. In-depth interviews were conducted with 25 academic experts (professors of public administration and environmental engineering at universities in Mazandaran province) and the heads of the National Iranian Gas Company in five regions of Iran using the "rich information" sampling method. Results: The results indicated that the environmental model of sustainable development in the Iranian gas industry had 15 dimensions in terms of causal conditions. 1. Services, 2. Safety and health requirements, 3. Social responsibility, (context condition) 4. Education and learning, 5. Acculturalization, 6. Managers' attitude and awareness (intervening conditions) 7. Contractors, 8. Technical facilities and equipment, 9. Technology and technical operations (Strategy) 10. Medium and long term policies of the Ministry of Energy, 11. Continuous monitoring and evaluation of project progress, 12. Consumption management programs, 13. Pollutants management programs and consequences 14. Improved environmental performance of the gas company and 15. Moving towards sustainable development. Conclusion: Since the gas industry is one of the most polluting industries and the lack of attention to environmental issues in this huge industry will lead the Iranian environment to very serious and perhaps irreparable crises, using the environmental model of sustainable development in this industry seems highly important and necessary.

purpose: The purpose of this research was to identify Dimensions and Components of Human Resource Efficiency in Medical Universities of Iran: To Present a Conceptual Model. Methods: This research regarding the aim of that is an applied research type and in terms of implementation method categories in descriptive-survey and correlational research applying the Delphi fuzzy model. The statistical population of the study consisted of 27 college experts who participated in this research as a decision team in identifying indicators and dimensions of variables chosen by non-random (targeted) and snowball methods Findings: The findings of the research show that human resource productivity indicators are divided into seven main categories (structural-managerial, socio-psychological, cultural, individual, economic, environmental, initiation and cooperation) and 56 subsidiary indexes.
