This study adds to the literature on energy studies on exploring for the first time to the best of our comprehension the importance of alternative measures of economic globalization indicators on energy-based demand in the context of economic complexity dynamics for 1971 to 2018 across a panel set of 63 countries classified as high-income (HIE), upper-middle-income (UME) and lower-middle-income countries (LME). Empirical results based on the panel ARDL model demonstrate i) the long-run relationships between economic complexity, economic globalization with energy demand; ii) economic complexity appears to increase energy-based demand in the short run, but it would reduce energy-based demand in the long run; iii) economic globalization is found to have decreasing effects in the short run and increasing effects in the longer run-on energy demand in LMEs and UMEs, while it has mixed effects in HIEs. The results suggest that policies supporting economic complexity would be a good strategy to aim at economic development while controlling for the increasing effects of globalization on energy demand to achieve long-term sustainable development. • Investigating the role of alternative measures of economic globalization on energy demand. • Across 63 countries segregated across varying income groups for the period 1971 to 2018. • The context of economic complexity dynamics is also explored. • Long-run relationships between economic globalization with energy demand is validated.

This paper explores the impact of an environmental tax on carbon emissions for the G7 nations from 1994 to 2014 and the importance of the major drivers of emissions such as energy use, economic complexity, natural resources rent and economic growth. The study also verifies the Environmental Kuznets Curve Hypothesis for the G7 countries and explores the marginal effects of an environmental tax on traditional energy consumption, natural resources rent and renewable energy consumption. This paper's unique contribution is that it investigates for the first time the moderating role of an environmental tax on renewable and non-renewable energy consumption, natural resources rent and CO 2 emissions. The results suggest that environmental taxes effectively reduce emissions for the G7 countries and confirm that the marginal effects of the environmental tax on traditional energy consumption, natural resources rent and renewable energy consumption rise with the level of taxation in a statistically significant way. The findings indicate that strict environmental tax laws will allow businesses to shift production towards cleaner methods. Finally, the paper proposes that redistributing tax revenues to the research and development of sustainable technology programmes would empower the nations to achieve the United Nations' SDG-7 and SDG-13 goals. Flow Diagram on the nexus between emissions, tax, economic complexity, energy and economic growth. [Display omitted] • The paper analyses the effects of economic complexity on carbon emissions. • Environmental tax affects directly carbon emissions. • Environmental tax lessens the effect of energy consumption and natural resources. • Environmental tax amplifies the effect of renewable energy consumption. • The EKC hypothesis is validated for economic complexity in G7.

The G7 countries consist of some of the world's most economically developed nations. However, alongside such robust economic growth performances, the environmental qualities in these countries have simultaneously aggravated to raise deep concerns among the stakeholders. Hence, this study is designed to empirically examine the environmental effects of nuclear and renewable energy consumption, economic complexity, and economic growth in the context of the G7 countries for the period between 1995 and 2016. To ensure novelty, this study considers carbon footprints along with carbon dioxide emissions to measure environmental quality in the context of the G7 nations. The results reveal that although nuclear energy consumption is effective in mitigating carbon dioxide emissions and carbon footprints in the long run, renewable energy consumption degrades the environment in the G7 countries. Besides, the results also suggest that the G7 countries can transform their production processes in an environmentally friendly manner provided they can undergo a clean transition in energy use. Finally, economic growth is evidenced to be detrimental for the environment since higher economic growth levels are seen to boost both carbon dioxide emission and carbon footprint levels. Therefore, in line with the findings, this study recommends the G7 countries to significantly enhance their nuclear and renewable energy consumption levels, increase their economic complexity indices, and integrate environmental welfare policies within their economic growth strategies. • Determinants of CO 2 emissions and carbon footprints are evaluated in G7 countries. • Renewable energy use boosts CO 2 emissions and carbon footprints. • Nuclear energy use curbs CO 2 emissions and carbon footprints. • Economic complexity reduces CO 2 emissions and carbon footprints. • Economic growth stimulates CO 2 emissions and carbon footprints.

This study investigates the dynamic interdependence between CO 2 emissions, real gross domestic product (GDP), renewable and non-renewable energy generation, urbanization, and export quality for both the top ten renewable energy and top ten economic complexity index (ECI) countries. The techniques of panel cointegration, long-run FMOLS, DOLS, and Granger causality are used spanning the period 1980–2014. Long-run estimates suggest that, for the top ten renewable energy countries, only renewable energy generation contributes to mitigating CO 2 emissions, while the other variables lead to increase emissions levels in the long-run. However, for the case of leading complex economies, the empirics highlighted the significant role of renewable energy in carbon mitigation. Exports quality leads to decrease emissions level and real GDP, non-renewable energy and urbanization contribute to the rise in emissions. Interestingly, for the top ten renewable energy countries, Granger causality analysis mentioned a two-ways short-run relationship between renewable energy generation and export quality and one-way causality from export quality to CO 2 emissions. The findings mention that adopting clean technologies using renewable energy might act as a key tool for export quality improvement and mitigation of CO 2 emissions. Results are related to Sustainable Development Goals (SDG-7: using more renewable, affordable energy; SDG-8: sustainable economic growth and decent employment for all, SDG-13: regulating emissions and promoting renewable energy) and discussed in this sense. • Dynamic interdependence between CO 2 emissions, energy generation, and exports quality is examined. • Panel data is used for renewable energy and economic complexity countries. • Export quality tend to have positive effects on CO 2 emissions. • Non-renewable energy induces pollution levels. • Renewable energy mitigates CO 2 emissions.
