The Purpose of this research is Provide a Green Audit Quality Model based on the Recommendations of the UK Financial Reporting Council (FRC) Assessment of Environmental Change.

The research method was mix method in terms of data type and the target population was 11 accounting and financial management specialists at the university level and 14 audit partners in the quantitative department. In this study, in the qualitative part, Meta-synthesis and Delphi analysis were used, and in the quantitative part, a Total Interpretive Structural Model was used to determine the most effective themes of the green audit quality model.  

The results of the research in the qualitative part indicate the existence of two main components and 11 propositional themes related to the quality of green auditing, and in the quantitative part assessing the level of corporate environmental risks for stakeholders is the most influential issue of green audit quality based on the assessment of the UK Financial Reporting Council.

The results reflect the fact that recognizing this level of risk can help competing companies and even investors to examine the level of progress of the company in terms of environmental technologies and its future prospects at the market level.

Energy is one of the most important inputs in production. Energy usage and energy diffusion of fossil fuels in process of production cause greenhouse gases (CO2) emission and destruction of environment. According to the importance of issues like energy usage and economic growth, this paper, concerning the effects of proximity, evaluates the effects of energy usage and economic growth on emission of Carbon dioxide (CO2) in MENA Zone countries during the period of 1994-2013. In every country, greenhouse gases (CO2) emission is the function of not only domestic factors but also economic activities of neighboring countries. 

In order to investigate the impact of energy consumption, economic growth and carbon dioxide emissions in the Middle East and North Africa, LM test was used to examine the spatial dependence between variables and then the research model was estimated using the spatial panel data approach.

The results of the model estimation indicate that proximity effect is verified in the model studying on. Also, the results show that log variable of energy usage has positive and significant effect on CO2 emission. Log variable of income per capita affects CO2 emission positively and significantly, and square log variable of per capita income has negative and significant effect on dependent variable.

Based on the research results, the environmental hypothesis of Kuznets is accepted for the studied countries. Therefore, reducing energy consumption can be suggested as a way to reduce pollution. Taking into account the effect of technology, two strategies can be proposed: firstly, the improvement of the technology of using fossil energies to increase energy efficiency and reduce pollution, and secondly, the use of renewable energy carriers and clean fuels.

Global warming is caused by the emission of greenhouse gases, mainly (CO2). Reducing greenhouse gases and monitoring the environment are important goals of today's mankind. Cement factories are the main producers of greenhouse gases. The main goal of this research is to find a material with cement properties (pozzolan) that can be replaced in a part of concrete cement with the aim of reducing cement consumption and reducing CO2 greenhouse gas emissions. The local mineral pozzolan under research has similar properties to world-famous pozzolans and has the relevant standards.

To find the optimal amount of pozzolan in the concrete, In Sep. 2021, four cases of 5, 10, 15 and 20% by weight was studied and its effect on concrete compressive strength and CO2 emissions and its ability to reduce pollution Environmental was evaluated in comparison with conventional cement concrete.  

Experiments showed that the best amount of replacement of this pozzolan to cement in concrete is 15% by weight and increases the strength by 2.4%. Also, this pozzolan emits less CO2 than normal cement concrete equal to 15.20 kg/m3.

Considering the favorable effects of this pozzolan in strengthening the structure and reducing the consumption of cement in concrete, it can be introduced as a cement-reducing and environmentally friendly material.

Intergenerational justice, which is the mainstay of the rights of future generations, states that the exploitation of resources, as well as the adoption of practices that affect the environment, must be such that, in addition to serving the interests of the present generation, the present generation in exploiting and dealing with the environment must behave in a way that preserves the interests of future generations. Article 50 of the Iranian Constitution explicitly emphasizes the protection of the environment. This principle raises many issues from a legal point of view and has a clear duty to protect the rights of the present and future generations to the right to a healthy environment and to observe intergenerational justice. In this principle, several points have been stated that are important for a more detailed study. First, there is the issue of environmental protection, in which case, the same issue of preserving and respecting the human right of society to a healthy environment is raised. Then there is the issue of intergenerational justice and identification. That is, it considers it the duty of everyone to observe fairness with current and future generations, as well as these issues, and the issue of public participation in environmental protection is raised. Like the constitution, it is necessary to be stated in this principle. In this descriptive-analytical study, an attempt has been made to examine the rights and obligations of intergenerational justice in order to achieve the goals of sustainable development (with emphasis on Article 50 of the Iranian Constitution).

One of the most prominent hypothesis in environmental economics is the Porter hypothesis. The Porter hypothesis argues that more stringent environmental policies can actually have a net positive effect on the competitiveness of regulated firms because such policies promote cost-cutting efficiency improvements, which in turn reduce or completely offset regulatory costs, and foster innovation in new technologies that may help firms achieve international technological leadership and expand market share. Given the importance of this hypothesis to policymakers and firms, many studies have been conducted to prove or disprove this hypothesis.

in this study, we used panel smooth transition regression for 25 OECD members during 2000-2015.

the results indicated that the weighted indicator of environmental policy stringency in linear and nonlinear part of the model had positive and significant effects on increasing the number of selected environmental technologies. The coefficient of variation was estimated to be 0.142 in the linear part and 0.213 in the nonlinear part. The speed of transition between the two regimes of weighted growth index of environmental policies, according to the estimated transition parameter, is 3.17.

Analysis of results shows that when the weight index growth of environmental policies is low, the severity of the impact of independent and control variables on the number of selected environmental technologies will vary. Given the experience of developed countries, improving the state of the legal system and property rights, increasing official and state aid for environmental development, and increasing state funding for environmental research and development can play an effective role in improving competitiveness and enhancing enterprise innovation.

In the current situation, planning and policy making is necessary to prevent the spread of environmental disasters and one of the most important issues in the country is the issue of Lake Urmia which in recent years, many policies have been approved that have not been sufficiently effective. The purpose of the current study is based on the approach of policy analysis.

The research strategy was applied in terms of purpose is practical and according to the nature of the problem, a qualitative research approach was chosen. The research method is a case study with the aim of describing and collecting data from semi-structured interviews and the data analysis method is quantitative content analysis. Participants are environmental experts who have relevant knowledge and experience in the subject. The baseline model based on the public policy analysis process diagram includes problem determination, goal setting, criteria decision making, option selection, option analysis, and option comparison.

Findings and studies of Lake Urmia, which are based on the views of the statistical community of policy makers and experts acknowledged that the process of destruction in the Lake Urmia basin has slowed down but the destruction of the environment in the country, 20% is due to the compiling of weak laws and regulations, 60% is due to non-compliance with full implementation of laws and economic valuation of the environment and the remaining 20% is due to how policies are evaluated.

As 100% of the statistical community of this research, including policy makers and experts, admitted that the process of destruction in the Urmia lake basin has slowed down, but the main reasons for the spread of environmental destruction in the country are the lack of adherence to the implementation of laws and the lack of economic valuation of the environment in the past years. This research was carried out in order to determine the problems and objectives of the existing policies in the Deparment of Environment. In this regard, it is suggested that this research should occur in the larger scope of other effective governmental organization in the area of Lake Urmia in order to restore and protect the wetland and provide water resources, including the Ministry of Energy, the Ministry of Agricultural, the Program and Budget Organization and their provincial units.

Today, issues related to health, safety, and the environment have become an integral part of every business and organization. Therefore, the purpose of this study was to identify and prioritize HSE risks in the transmission lines of Chaharmahal and Bakhtiari Province Gas Company by Meta-Synthesis and fuzzy dimethyl methods.

In the qualitative section, data were collected using the seven-step "Barso and Sandlowski" meta-Synthesis method. The qualitative statistical population included articles and researches in the field of research between 2000 and 2021. Finally, 26 researches related to purposive sampling were selected. This research was conducted in 2023.

After documenting these studies, 627 open source codes were identified in the form of three main criteria and eleven sub-criteria, including: safety criteria (performance and lack of equipment, leaks and overflows, falls and falls, Professional quality of human factors, environmental factors, levels and harmful substances and incendiary agents and shocks), health (physical and human injuries and workplace challenges) and environment (air pollution, pollution Soil and water pollution) and The quality of the research was measured by Laosheh methods with a value of 0.81 and the reproducibility index with a value of 0.81 and finally the research model was designed using MAXDA software.

The results showed that the professional quality of human factors, physical and human injuries, and performance and lack of equipment had the highest priority, respectively and Also, the professional quality of human factors was the most influential) Cause (and physical and human injuries were the most influential (Effect).

the climate factors are main determinant of vegetation spatiotemporal dynamics. A visual comparison of climate and vegetation on a global scale immediately reveals a strong association between climate and vegetation.  The main object of this study is to reveal the spatiotemporal association between climatic factors and Modis derived NDVI in Charmahal & Bakhtiary province of Iran.

In this study, we use MOD13A3 of MODIS product as NDVI layer for study area. MOD11A2 as land surface temperature and mean monthly accumulative rainfall of synoptic station for study area during 2008 to 2018. We used the correlation analysis in 0.95 confident level (P_value =0.5) to reveal the spatiotemporal association between the NDVI and climatic factors.

The results indicated that during winter (December to March) the spatial distribution of NDVI is highly correlated with LST spatial distribution. In these months, the pixels which have the high value of NDVI are spatially associated with the pixels which have highest value of LST (6 to 12C°). In winter the spatial correlation between NDVI and LST is so high which is statistical significant in 0.95 confident level. In transient months such as May, October and November, the spatial correlation between NDVI and LST is falling to 0.30 to 0.35, which is not statistical, significant in 0.95 confident level. Finally, in summer season or warm months including Jun to September, we found the minimum spatial association between the NDVI and LST.

we found that the maximum correlation between NDVI and LST simultaneously appears and no lag time has been observed. The spatial correlation of NDVI and monthly accumulative rainfall was statistical significant in spring season (April to Jun) by 1-month lag time but in other months we do not find any significant correlation between NDVI and rainfall.

Considering the important role of Freecycle website and Freecycling culture in reducing the amount of waste in collection and disposal sites through the flow of donating extra items from website users to others and thus reducing environmental damage. ; And on the other hand, the lack of this website and flow in Iran, the current research on the identification of factors influencing the culture of free cycling in Iran through social networks (considering the strong presence of these networks in the daily life of people in the society and their role in culture) creation of environmental protection) is concentrated and therefore it is of the type of applied research.

The data collection in this research was done through in-depth interviews with experts in the field of media, cyberspace, virtual networks and also experts in the field of environmental protection in the country, and then the data were collected using the method Qualitative content analysis was analyzed through open, central and selective coding and finally a research model was presented.

According to the main problem of the research, the categories related to the factors affecting the culture of free-cycling in Iran were extracted in the form of five main categories: prerequisites-tools-methods-effects-results.

Considering that the people of Iran have shown and proven their willingness to help their fellow citizens in various and sensitive situations (such as floods, earthquakes, etc.) are willing to provide their additional items to different regions of the country and even abroad; Therefore, it seems that they welcome actions such as participating in free cycling and donating their second-hand and unusable items (but needed by others), especially when its effects are supposed to be on the health of people in the community and the environment. Their lives should return to themselves.

Exceptional schools which accept children with special educational needs, including children with intellectual disabilities, should regard educational goals and meet their specific physical and mental needs in school building design .one of the most important one is improving adaptive skills. This study seeks to find criteria for landscape design of exceptional schools, in order to prepare children with intellectual disability for independent living, by improving their adaptive skills.

The method used in this research is qualitative-quantitative and is based on Delphi type of exploratory research  .Correlation test and multiple linear regression was used to test the research hypotheses. Based on the aims and hypotheses of the research, architectural solutions were asked from the architects and after achieving the most important strategies, in order to ensure the accuracy of the data, a survey was conducted and teachers in special schools were asked if the solutions improve adaptive skills.

design of simulated spaces with community, home-like school environment, accessibility, participatory spaces, paly ful spaces, attention to the color, form, material are the principles should be regarded in landscape design of special schools.

Regarding these principles, provide such an environment which encourage participation and communication, direct connection with nature, sensory stimulating by color, music, texture, and the possibility of group games and as the result of the activities occur, adaptive skills will increased.
