The jeopardizing of ecological security due to the detrimental effects of human activities necessitates the adoption of various actions to reduce ecological intensity. Though some studies have explored the moderating impact of financial development (FND) towards achieving ecological security, in Arab World it has not been thoroughly investigated. Against this backdrop, we investigate combined role of agricultural production (AFP), gross domestic product (GDP), energy consumption, population, direct and moderating impacts of FND on ecological intensity for a panel of 12 Arab League member states from 1995 to 2021. The empirical outcomes unveiled that AFP and GDP have U-shaped nexus with ecological intensity. It posits that at early stages of AFP, ecological intensity is reduced to a certain level, beyond which higher AFPhinders ecological security supporting the evidence against the Borlaug hypothesis. Our findings further unfolded that environmental Kuznets curve (EKC) hypothesis does not hold for the selected Arab League member states, denoting that real GDP has a U-shaped relationship with ecological intensity. Further findings confirm that energy consumption induces ecological deterioration in the absence of its interaction with FND, along with the interaction term. The causality results largely support these outcomes. Based on these findings, Arab League's climate-related policies should further explore FND to drive energy transition and environmentally friendly measures. • Examination of Borlaug and EKC hypotheses in the Arab League. • Borlaug hypothesis is validated i.e. of a U-shaped nexus between agricultural production and ecological intensity. • EKC hypothesis is invalid i.e. Real GDP per capital has a U-shaped relationship with ecological intensity. • Neither the aspect of financial markets and institutions promote environmental quality. • Energy usage, population, and financial development spur ecological deterioration.

This study provides empirical evidence on the relationship between energy efficiency and production- and-consumption based carbon emissions by assessing the impact of population size, income, and clean energy on the carbon dioxide (CO 2) emissions function. Method of Moments Quantile Regression (MM-QR) and Augmented Mean Group (AMG) estimators are applied to observe long-term associations between the variables, and Dumitrescu-Hurlin (DH) Ganger causality test is used to identify the direction of causality. Findings reveal that, across all specifications, energy intensity and population size have positive (increasing) impact on both estimates of CO 2 emissions while renewable energy use has a negatively significant impact and stronger on consumption-based estimates. The presence of an inverted U-shaped curve in the relationship between per capita income and CO 2 emissions, as predicted by the Environment Kuznets curve (EKC) hypothesis, only exists when CO 2 emissions are calculated based on production pattern. Further empirical analysis based on DH causality tests show a bidirectional causality between energy intensity and production-based CO 2 emissions, population size and consumption-based CO 2 emissions, per capita income and consumption-based CO 2 emissions, and energy intensity and renewable energy use. In addition, a unidirectional causality runs from per capita income to production-based CO 2 emissions, and from energy intensity and renewable energy use to consumption-based CO 2 emissions. This analysis outlines a paradigm for the formulation of a green development strategy in developing economies via energy and environmental resources. • This study explore nexus between energy efficiency and carbon emissions Production-based. • Method of Moments Quantile Regression (MM-QR) and Augmented Mean Group (AMG) estimators are used. • Validity of inverted U-shaped curve in the relationship GDP and production-based CO 2. • Bidirectional causality exists between energy intensity and production-based carbon emissions. • Green growth policies should be pursued in the developing energy mix.

The emerging industrialized seven (E7) economies are not excluded from the global warming issues which is a major problem for most economies. The E7 member countries have partaken in policies to mitigate against global warming in terms of decoupling CO 2 emission from economic growth trajectory in the highlighted economies. It is on this premise that the present study is motivated to consider the connection among economic growth, pollutant emissions, coal rent while accounting for the role of other co-variates such as CO 2 damage and energy from a nuclear energy source, oil gas energy between 1990 and 2016 on an annual frequency. This study adopts the use of panel ordinary least squares alongside panel quantile regression to explore the coal rent-energy and environment nexus. The empirical result shows a positive and significant effect of both real GDP and coal rent on CO 2 emissions. More precisely, a 1% increase in GDP growth increases pollution emission by 0.400% while for coal rent, an increase in coal consumption dampens environmental quality by 0.088% as reported by the panel regression which is resonated by the quantile regression estimations at different tails of the data. Nevertheless, we observe that 0.95 percentile GDP growth strongly contributes to environmental pollution while at the median tail i.e. 0.5 percentile renewable energy consumption dampens the adverse effect of environmental degradation. Additionally, renewable energy, on the other hand, was found a negative and significant impact on CO 2 emissions in E7 countries as a 1% increase in renewable energy consumption improves environmental quality by 0.588% Moreover, the estimated results indicate that regulation of coal consumption through the rent in addition to the cost of carbon damage will further increase the CO 2 emissions in E7 countries. This study implies that putting stringent regulations on coal consumption as it concerns the increasing cost of carbon damage will not be of help to environmental sustainability within the E7 economies. The adoption of renewable energy consumption, nuclear energy, oil energy will reduce CO 2 emissions in E7 countries. Thus, suggesting a paradigm shift for low-carbon energy sources which are more environmentally friendly. [Display omitted] • We explore the nexus between renewables, nuclear, coal, oil, gas energy on CO 2 emission in E7. • Coal rent and renewable energy decreases CO 2 emission in E7 countries. • Energy diversification in the E7 countries can abate global dwindling energy market. • Environmental sustainability is obtained by decoupling CO 2 emission from economic growth.
