The Moroccan government has always advocated reducing energy intensity so as to reach the target of the sustainable development. The current study presents the connection between CO2 emission, energy intensity (EI), natural resource rents (NRRs), energy productivity (EP), and renewable energy (RE) by employing annual time-series data from 1990–2020 for Morocco. Using the ARDL model, the empirical findings illustrate that (i) increasing EI significantly contributes to carbon emissions, (ii) higher consumption of natural resources adversely affects CO2 emissions, and (iii) EP and RE are the key factors to mitigate carbon emissions in both the short term and long term, suggesting that these two factors strengthen the considerable impact of EI and the consumption of natural resources on carbon emissions. Nevertheless, the negative environmental effects are moderately neutralized by adopting significant clean and green energy consumption within the country. The outputs of the robustness test verify the reliability of the regression results. Moreover, a one-way Granger causality running from EI, EP, RE, and NRR to CO2 emissions indicates that any variation in these variables will cause CO2 emissions. The present study offers the latest insights by adding EP and RE into country development and will support government policy makers in decisions related to efficiently abating CO2 emissions.

Carbon neutrality has been widely acknowledged as a challenge to environmental mitigation and global climate change policy. The current study examines the association between collaboration in climate change mitigation technologies (CMTs), energy productivity (EP), natural resources rent (NRR), renewable energy consumption (REC), and environmentally related tax (ET) on CO2 emissions for a panel dataset of 30 OECD economies from 1990 to 2020. This paper employs panel data econometric techniques such as AMG, CCEMG, and CS-ARDL. The empirical outcomes show that CMTs, EP, REC, and ET have a negative effect on CO2 emissions, indicating that their increase will bring about the reduction of carbon emissions, whereas NRR has a positive impact on CO2 emissions, suggesting that its increase will raise CO2 emissions. Most interestingly, REC and EP play a leading role in all selected variables by decarbonizing and effectively converting conventional energy into clean, green energy in the process of energy production and utilization. Finally, the OECD countries are anticipated to transition their energy from conventional resources to renewable sources, which will be validated by the increase in energy productivity and the adoption of clean and green technology in the short term.

AbstractAgriculture is one of the primary contributors to Pakistan's economy. However, over the last few decades, the atmospheric carbon dioxide emission has been amplified to a great extent in Pakistan. This amplification may cause climate change, global warming, and environmental mitigation in Pakistan. This paper empirically investigates the impact of CO2 emissions on the agricultural export trade of Pakistan over the period 1975–2017. Evidence suggests that climate change could be a primary cause for the decline in Pakistan's agriculture export trade; no studies have been carried out for this specific issue, particularly over time. In this paper, the empirical analysis suggests the negative coefficient of agriculture export trade with CO2 emissions subsequently decreases agriculture export trade, which leads to direct impact on Pakistan's economy. Both theoretical and empirical outcomes suggest that the adaptation of clean and green energies and technologies are the key to reduce pollution in Pakistan. Overall, the effects of carbon dioxide emissions on agriculture export trade are stronger in the long‐run dynamics, thus making the finding heterogeneous. Possible initiatives should be taken by the government of Pakistan to improve the agriculture sector and it should also introduce new policies to reduce the emissions of carbon dioxide.

This study aims to investigate the relationship between carbon emissions (CO2) and economic policy uncertainty for East Asian countries. During recent decades, climate change has become a severe issue globally. To our understanding, the impact of economic policy uncertainty (EPU) on CO2 emissions has not been thoroughly studied in the environment-energy literature. To overcome this research gap, this study explores the link between EPU, CO2 emissions, foreign direct investment (FDI), and renewable energy for the panel of four East Asian economies, namely, China, Japan, South Korea, and Singapore, from 1997 to 2020. We used second-generation econometric estimations to confirm cross-sectional dependence, cointegration, and stationarity among the selected variables. This study finds that economic policy uncertanity (EPU), trade, and GDP have a positive correlation with carbon emissions. However, FDI and renewable energy consumption boost the quality of the environment of East Asian economies. The outcomes of the Dumitrescu-Hurlin panel causality estimation revealed two-way association between CO2 and economic policy uncertainty, CO2 and energy consumption, CO2 and economic growth, and CO2 and trade. Afterward, we use the FMOLS estimations for robustness check. Based on the inclusive outcomes, we draw substantial suggestions for decision-makers and urge them to consider the potential negative effects of EPU on CO2 emissions policies. In addition to this, if policymakers seek to simultaneously control EPU and CO2 emissions, they should work out for alternate ways such as the use of green technology related to energy, foreign capital investment, and renewable energy consumption to mitigate CO2 emissions.

The staggering rise in global temperature and abrupt change of climate are the responses of nature alerting humanity to limit the emissions of hazardous gases and adopt environmentally-benign life style. The present study explores empirically whether any changes in environmental policy stringency (EPSI), political risk (PR), and the interaction term of EPSI*PR result in any alteration of consumption-based carbon emissions (CBCE) of the 24 advanced OECD economies over the period of 1990-2020. Prior to the empirical estimations, various diagnostic tests are employed. The empirical techniques include, panel cointegration check, Cross-sectional Augmented Autoregressive Distributed Lags (CS-ARDL), and Dumitrescu & Hurlin panel causality test. The findings confirm that imports, gross domestic product, and stringency of environment policies activate CBCE in short-run. Whereas, a unit improvement in political risk and its interaction with environmental policy stringency give rise to 0.231 MtCO2 of CBCE in long run. Interestingly, the squared term of environmental policy stringency effectively tackles such emissions. Based on the findings, we conclude that the present environment related policies of OECD member states does not effectively limit CBCE. In order to achieve genuine emissions reduction goals, the selected nations should restructure their environment related policies by prioritizing increments in environmental policy stringency along with minimizing the risks involved in the political system.

To sustain global warming below 2 °C, carbon dioxide emission mitigation has become an extensive worldwide priority. This paper proposes a comprehensive assessment by evaluating the effects of technology transfer, human capital, and renewable energy on carbon dioxide emissions among seven different regions along with the Belt and Road Initiatives from 2008 to 2018. Based on econometric estimations, it is found that human capital, renewable energy, and technology transfer show a negative but significant association with carbon dioxide emissions, indicating that an increase in human capital, renewable energy, and technology transfer can reduce carbon dioxide emissions in the Belt and Road countries. On the other hand, we found a positive and significant relationship between carbon dioxide emissions, economic growth, and foreign direct investment (FDI), indicating that economic growth and foreign direct investment increase carbon emissions. The findings of this study reveal that the adaptation of technology transfer, renewable energy consumption, and human capital are key factors in the reduction of carbon dioxide emissions in the Belt and Road counties. Our findings provide evidence of the social advantages of investing in advanced human capital, renewable energy, and technology transfer suggesting a promising route for devoting climate change without impeding economic growth.

Conventional energy consumption such as coal, natural gas, and oil is a source of deteriorating environmental sustainability as well as a severe challenge to the green environment. The present paper explores the nexus between CO2 emissions, energy imports, energy intensity, and power generation from renewable and non-renewable energies from 1990 to 2021 in Australia. Based on the ARDL model, the findings reveal that energy imports and power generation from non-renewable energy sources show an adverse effect on the green environment. A 1% increase in conventional energy imports leads to an 11% increase in CO2 emissions. Similarly, a 1% increase in energy generation from conventional sources will increase CO2 emissions by 45%. On the other hand, lower energy intensity and power generation from renewable sources reveal a positive effect on environmental quality. A 1% increase in energy intensity will decrease CO2 emissions by 92% while energy generation from non-conventional sources by 15%. Most interestingly, energy intensity reveals the foremost position among all the selected variables to decarbonize and effectively transform conventional energy to clean and green energy production and utilization. The robustness test outcomes confirm the results of the empirical output. Furthermore, this study suggests that governments and policymakers should focus on the adaptation of lower energy intensity for the purpose to reduce CO2 emissions and promote a clean and green environment. Finally, power generation from renewable energy sources plays an inevitable role which ultimately helps environmentally sustainability in Australia.

This paper empirically examines the nexus between CO2 emissions and international trade for the 65 Belt and Road Initiative (BRI) economies over the period of 1985–2017. We first consider the cross-sectional dependence and slope homogeneity test in the panel, and we observed from the results that there is substantial heterogeneity and cross-sectional dependence. We employed the results of the common correlated effects mean group (CCEMG) estimator and determined that for all 65 BRI economies, foreign direct investment inflow, gross domestic product (GDP) squared and urbanization had a positive and significant impact on carbon emissions (CO2). Moreover, this study found that foreign direct investment inflow led to an increase in carbon emissions in BRI countries across South Asia, Southeast Asia, East Asia and Europe. Finally, on the basis of the panel causality test, we found evidence of various causality associations among the selected variables across the regions. These findings are significant for the related policymakers in BRI countries, as they can assist in developing appropriate carbon emission, trade and energy policies with the goal of reducing carbon emissions.
