The agriculture sector may help to improve the environment of any country. The purpose of this research is to test the existence of environmental Kuznets curve (EKC) hypothesis while keeping the energy consumption and agriculture share in income into account and analyze their effects on the CO2 emissions per capita of Saudi Arabia. We test both symmetrical, asymmetrical and quadratic effects of agriculture sector on the CO2 emissions. An inverted U-shaped relationship between gross domestic product (GDP) per capita and CO2 emissions per capita is found. Hence, EKC hypothesis is validated with a turning point at GDP per capita of 77,068 constant Saudi Riyal. Further, a negative and significant effect of agriculture sector on the CO2 emissions per capita has been found both in symmetrical and asymmetrical analyses. The magnitudes of effects of increasing and decreasing agriculture share are found statistically different on the CO2 emissions, and rising agriculture share in GDP has larger effect than that of decreasing agriculture share. An inverted U-shaped relationship is also found between agriculture share in GDP and CO2 emissions per capita with a turning point at 3.22% agriculture share in GDP.

For this said objective data was gathered from owners and managers of 100 small and medium-sized manufacturing enterprises in operating in Lahore, Sialkot, Faisalabad, Karachi, Gujranwala, Gujrat, and Rawalpindi/Islamabad through cluster sampling. The data was gathered through surveys, and structural equation modeling was run to analyze the relationships. The findings revealed that sustainable leadership has a significant impact on psychological safety and sustainable performance of SMEs, whereas psychological safety showed an insignificant effect over sustainable performance of SMEs, but the mediating role of psychological safety was found to be significant. Likewise, employee empowerment direct influence sustainable performance and holds a significant moderating role. The findings of the research are significant for practitioners as well as academicians because it revealed that owners and managers should design strategies to encourage employee empowerment and to provide them psychological safety. The findings of the study are limited on the data collected from owners and managers without involving any other stakeholders. Therefore, in future researchers are guided to involve other stakeholders as well in the study.
