    Exploring the impact of economic growth on environmental pollution in South American countries: how does renewable energy and globalization matter?

    Most emerging economies and the South American Countries are no exception to the negative consequences of trade-off between economic growth and environmental sustainability decisions. This study draws strength from the United Nations Sustainable Development Goals (UN-SDGs-7, 11, 12, and 13). Therefore, this study examines the environmental nexus between economic growth, globalization, renewable, and non-renewable energy, in South America from 1995 to 2020. We deployed the pooled mean group (PMG), mean group (MG), and dynamic fixed effects (DFE). Cross-sectional dependence, panel unit root, and cointegration tests were performed. Finally, we used the Dumitrescu and Hurlin test of causality to determine the long-run association between variables. The finding indicates that while environmental pollution increases with increasing economic growth, it decreases with increasing renewable energy both in the short and long term. Whereas economic globalization positively affects environmental pollution in the long term, social globalization and the moderation effect between political globalization and renewable energy improves environmental quality in the long run. Finally, a bidirectional causality was found between economic growth and environmental pollution, with a unidirectional causality running from economic, political, and social globalization, renewable, and non-renewable energy to environmental pollution. Given these findings, we discussed potential policy measures.

    How do environmental tax and renewable energy contribute to ecological sustainability? New evidence from top renewable energy countries

    The recent COP27 has propelled nations towards achieving reduced environmental degradation. Governments are, therefore, required to develop effective policy tools to improve their environmental sustainability plans. In line with this, an empirical study is required to explore the all-inclusive effect of ecological sustainability policy on ecological footprint (EFP) among the world’s top renewable energy consumption countries from 1994 to 2018. Recent studies on environmental degradation have focused on renewable energy while neglecting the role of environmental tax. Thus, the current study fills this gap by exploring the role of environmental tax on ecological footprint. Furthermore, the study evaluates the direct and indirect impact of environmental tax and renewable energy on different levels of EFP using the method of moment quantile regression (MMQR). The DOLS, FMOLS, and panel GMM techniques are also applied to check the robustness of the MMQR results. The empirical results indicate that environmental tax and renewable energy directly and significantly reduce the EFP; however, these impacts are insignificant in countries with lower levels of environmental pollution. Furthermore, the findings indicate that environmental tax plays a leading role in changing the energy structure towards environmentally friendly energies. The results also show that economic globalization and human capital impact ecological footprint negatively. Finally, the results suggest that GDP and nonrenewable energy aggravates ecological footprint. The study results propose insights for policymakers to mitigate environmental degradation by boosting environmental tax to deter polluters and investing more in renewable energy development.

    The role of technology innovation, R&D, and quality governance in pollution mitigation for EU economies: fresh evidence from method of moment quantile regression
    (Taylor and Francis, 2022) Baba Ali, Ernest; Radmehr, Riza; Shayanmehr, Samira; Gyamfi, Bright Akwasi; P. Anufriev, Valery
    Human progress has become detrimental to the environment. Moreover, the failure to mitigate pollution would eventually impact negatively on the economy. This study investigates the influence of technological innovation, research and development, and quality of governance on carbon emissions for the European Union countries while controlling for industrialization, renewable energy, trade openness and foreign direct investment from 1996 to 2018 by employing the method of moment quantile regression technique. The result revealed that renewable energy, trade openness, and quality governance boost environmental quality, while technological innovation and industrialization increase carbon emissions. Also, the interaction between technological innovation and quality governance, research and development and quality governance as well as industrialization and quality governance decreases carbon emission while that of foreign direct investment and quality governance increases carbon emission. From the causality analysis, there is a bidirectional relationship between research and development and carbon emission, technology innovation and carbon emission, renewable energy and carbon emission, trade openness and carbon emission as well as industrialization and carbon emission. Moreover, a unidirectional connection was obtained between foreign direct investment and carbon emission, as well as quality governance and carbon emission. Based on the outcomes, comprehensive policy directions are suggested for policymakers in these countries.
