Can Energy Productivity Gains Harness the Carbon Dioxide-Inhibiting Agenda of the Next 11 Countries? Implications for Achieving Sustainable Development
(John Wiley & Sons, 2022-09-04) Murshed, Muntasir; Khan, Uzma; Khan, Aarif Mohammad; Ozturk, Ilhan
The Next 11 countries are among the world's most rapidly emerging economies that are poised to becoming key drivers of the global economy. Nonetheless, despite progressing economically, these nations have experienced persistent deterioration in their environmental conditions. Hence, this study specifically investigates whether energy productivity gains, controlling for financial inclusion, renewable energy use, economic growth, international trade, and urbanization, can harness the carbon dioxide emissions (CO2E)-inhibiting objectives of the Next 11 countries. The empirical analysis, using annual data spanning from 2004 to 2020, involves the application of advanced econometric tools that are robust to handling the cross-sectional dependency and slope heterogeneity-related issues. The results from the econometric analysis indicate that although energy productivity gains and greater renewable energy consumption reduce emissions of carbon dioxide, making the financial system more inclusive tends to amplify the emission levels. More importantly, energy productivity gains and financial inclusion are observed to jointly reduce the CO2E figures of the Next 11 countries. Thus, it can be said that making more productive use of energy can, to some extent, neutralize the adverse environmenntal impacts of financial inclusion. Additionally, higher economic growth, greater international trade participation, and urbanization are evidenced to boost CO2E in these countries while higher renewable energy use is observed to curb the emission levels. Furthermore, heterogeneous country-specific outcomes are also witnessed. In particular, energy productivity improvement is seen to curb CO2E in eight of these nations while a simultaneous rise in the levels of energy productivity and financial inclusion is found to jointly mitigate and boost CO2E in 55% and 18% of the Next 11 nations, respectively. Hence, in line with these key findings, a set of critically important environmental development-related policies are suggested.
Can Utilising Renewable and Nuclear Energy Harness the Environmental Sustainability Agenda of the G7 Countries? The Importance of Undergoing Clean Energy Transition
(Springer, 2022-12-25) Murshed, Muntasir; Khan, Aarif Mohammad; Khan, Uzma; Khan, Mohammad Shahfaraz; Parvin, Rawnaq Ara
Safeguarding environmental well-being has become a core agenda worldwide. In this regard, phasing out dependency on unclean fossil fuels and adopting cleaner energy alternatives is recognised as a prioritised energy policy reform. Therefore, this study investigates the dynamic impacts of renewable and nuclear energy uses on the ecological footprint figures of the G7 countries. The overall results reveal that enhancing renewable energy consumption and renewable electricity production are effective in reducing ecological footprints. However, simply increasing the nuclear energy consumption and electricity production levels are not enough to curb the ecological footprints. Rather, it is essential to scale the shares of nuclear energy in total final energy consumption and electricity output levels of the G7 nations. Thus, these key findings collectively portray the relevance of undergoing a clean energy transition in tackling environmental adversities in these developed countries. Moreover, the results verify the Environmental Kuznets Curve hypothesis while international trade is evidenced to further reduce ecological footprints.
Going Away or Going Green in NAFTA Nations? Linking Natural Resources, Energy Utilization, and Environmental Sustainability Through the Lens of the EKC Hypothesis
(Elsevier, 22-12-01) Jahanger, Atif; Yu, Yang; Hossain, Mohammad Razib; Murshed, Muntasir; -Lorente, Daniel Balsalobre; Khan, Uzma
This current study provides new insight by presenting the role of natural resources and renewable energy use in affecting carbon emissions in the background of the Environmental Kuznets Curve (EKC) hypothesis for the members of the North American Free Trade Agreement (NAFTA) considering the period from 1990 to 2018. Besides, the analysis controls for the influx of FDI to assess the validity of the pollution haven hypothesis as well. The results unveil the existence of the EKC hypothesis by verifying an inverted U-shaped association between economic growth and carbon emissions, only in the long run. Besides, evidence regarding the environmental resource curse is also revealed as higher natural resource consumption is seen to trigger a higher discharge of carbon dioxide both in the short- and long-run. Moreover, only in the long-run, higher renewable energy consumption is associated with lower volumes of carbon emissions. In addition, the pollution haven hypothesis is found to be invalid both in the short- and long-run. Lastly, the ratification of NAFTA is evidenced to foster economic progress but inhibit environmental sustainability for its members in the long run. Hence, it can be said that the NAFTA countries are going away rather than going green. Furthermore, these findings are mostly seen to be heterogeneous, in terms of magnitude, across different environmental pollution quantiles. Lastly, the analysis unearths unidirectional causalities extending from economic growth, renewable energy consumption, and foreign direct investment inflows to carbon dioxide emissions without the respective feedback causality. In light of these major findings, this study recommends some critically important policies.
Roles of Green Intellectual Capital Facets on Environmental Sustainability in Oman
(Informa UK Limited, 2022-12-05) Gharib, Moaz; Alam, Md Shabbir; Hawaldar, Iqbal Thonse; Murshed, Muntasir; Khan, Uzma; Alvarado, Rafael; Rehman, Ijazur
The present study determines the impacts of different types of green intellectual capital such as green human capital, green structural capital, and green relational capital on environmental sustainability in the Sultanate of Oman. It has become a crucial aspect to analyze the effect of green intellectual capital on ecological sustainability. A simple random sample technique is used to assemble data using a structured questionnaire from 205 respondents working at Raysut Cement Company and Salalah Methanol Company in Oman. The covariance-based equation in the structural modeling perspective is used to examine data. The study’s results reveal that green structure-based capital is the only dimension of green Intellectual capital that significantly affects environmental sustainability. In contrast, green human capital and relation-based capital do not substantially affect ecological sustainability. Conclusively, this study also provides ecological strategies that can be useful to enrich organizations to accomplish sustainability.

The role of renewable energy finance in achieving low-carbon growth:
(Daffodil International University, 2023) Siddik, Abu Bakkar; Khan, Samiha; Khan, Uzma; Yong, Li; Murshed, Muntasir
Although switching from non-renewable to renewable energy is believed to stimulate low-carbon economic growth, the means to establishing this energy transition have largely remained unexplored in the extant literature. Against this backdrop, this study focuses on evaluating how scaling public investment in renewable energy-related research and development projects impacts the carbon productivity levels in the top-10 renewable energy-investing countries. The estimation strategy comprised econometric methods that can handle cross-sectional dependency and slope heterogeneity related concerns in the data. Regarding the key findings, higher public research and development-related investments in renewable energy are observed to boost carbon productivity levels in the concerned countries, while natural resource consumption and net exports are found to reduce carbon productivity. Besides, the results endorsed that public research and development investment for renewable energy development exhibits a moderating role by jointly boosting carbon productivity with higher natural resource consumption and net exports. Moreover, it is also seen to inflict a mediating effect by jointly boosting carbon productivity with urbanization. In line with these findings, the concerned governments are recommended to scale such investment in order to stimulate technological innovation so that renewable energy transition can take place to establish low carbon economic growth.
