Environmental Sustainability

In this study, I try to examine the effect of environmental sustainability on CEO risk taking. Prior research, however, has struggled to establish this relation empirically; moreover, some evidence points to the possibility that the CEO risk appetite is lower for firms with sustainable environment. The opportunistic approach of managers leads to decisions about personal interests and imposing costs on shareholders by decreasing risk taking. In order to investigate the issue, data on companies listed in Tehran Stock Exchange for the period 2008-2018 were extracted and a panel regression model was used to test the research hypotheses. Consistent with expected relation between CEO risk taking and the environmental sustainability, It decreases with respect to CEO opportunistic approach. Managers may benefit from increased fluctuations in risk orientation, but are more sensitive than shareholders and have less restrictive choice that avoids higher risk.

One of the main reasons of unsustainability of city development in Iran is that planners and mayors have not almost been able to create connections between different dimensions of a city. Sustainability indicators are evaluation tools of cities operation applicable in living environmental, economical, and social aspects. The purpose of this paper is to offer a framework including the description of wide specter of indicators, with regard to the operation of environmental sustainability indicators. In order to have a common framework for sustainable indicators of Iranian new town, we create a charter in America and Australia. Therefore, we will study some samples of sustainable cities according to the documents and library related studies and comparative method of study. The result of this paper is as follows: The introduction of sustainability indicators for codification of sustainability indicators of Iranian new town.

Purpose- Medicinal plants have a special value and significance in providing hygiene, health and food resources. Although the human attitude towards the products of medicinal plants has a long history, the issue of increasing the production of these products at the level of fields and gardens has taken on a new scientific form since the second half of the 20th century. The purpose of this research is to assess and measure economic, social, environmental sustainability of expanding the activities of medicinal plants in the rural development in Kohgiluyeh and Boyer Ahmad province.Design/methodology/approach- It is an applied descriptive research based on field data collection (questionnaire). The statistical population of this research included 13 villages in cold region of Kohgiluyeh and Boyer Ahmad province. According to a report by Natural Resources of the Province in 2022, 383 medicinal plant producers were determined and among all of whom the questionnaires were distributed. Descriptive statistics (mean, standard deviation and variance) and inferential (one-sample t-test and VIKOR model) were used for data analysis.Findings- The findings showed that the mean score of the social and environmental indicators is over the theoretical average value (3), while the mean score was 2.80 in terms of economic indicators. The results of VIKOR model revealed that Sepidar village with a VIKOR index of (0.157) has the highest rank and Sadat Mahmoudi village with a VIKOR index of (0.993) has the lowest rank in terms of the sustainability of the activities of medicinal plants among the villages in the study area.Original/value- This study is promising the activities of rural areas in the production of medicinal plants, which is considered as a strategy for diversification in rural settlements. Therefore, the results of this research can be given special consideration in recognizing the effects of medicinal plants in different geographical areas and have an effective role in the development of rural areas.

This study examined the correlation between economic growth and the impact on the environment, specifically focusing on the concept of environmental sustainability. The World Bank's Adjusted Net Savings (ANS) data is utilized in this study to gauge the strain on the environment, specifically through the measurement of natural disinvestment. This measurement encompasses the cumulative effects of carbon dioxide (CO2) damage, as well as depletions in minerals, energy, and forest resources. This study uses panel data with respect to the endogeneity of explanatory variables to estimate the real effect of per capita income and the other variables on environmental pressure. In this regard, employing the panel Fixed-Effects Instrumental Variable (IV) methodology, the data from 213 countries have been used in the period from 1990 to 2018. Through regression analysis, it has been discovered that there is a direct correlation between income and the impact on the environment in developing nations. However, this relationship is notably more pronounced in low-income countries compared to high-income countries. Additionally, the study reveals that trade expansion contributes to an increase in environmental pressure across all groups of countries. An increase in the school enrolment rate can affect the environment in developed and high-income developing countries. Moreover, the variable effect of capital openness on environmental pressure was estimated to be positive for developed and high-income countries. However, this effect was found to be negative for low-income countries. Finally, the result showed that developing countries should improve their legal structure and also reduce the bureaucracy and complexity of the laws.
