Geographic Perspective

Renewable energy consumption (REC) has an important significance in mitigating CO2 emissions. However, currently, few scientists have analyzed the underlying impact of REC from a global geographic perspective. Thus, here, we divide the world into seven regions to study this impact during the period 1971–2016 using the logarithmic mean Divisia index (LMDI). These regions were East Asia and the Pacific (EAP), Europe and Central Asia (ECA), Latin America and the Caribbean (LAC), Middle East and North Africa (MENA), North America (NA), South Asia (SA), and Sub-Saharan Africa (SSA). The results showed that ECA had the most obviously mitigating effect of −10.13%, followed by NA and MENA (−3.91% and −3.87%, respectively). Inversely, EAP had the largest driving effect of 4.12%, followed by SA (3.43%) and the others. Globally, REC had an overall mitigating contribution of −11.04% to total CO2 change. These results indicate that it is still important to exploit and utilize renewable energy, especially in presently developing or underdeveloped countries. Moreover, for some countries at a certain stage, their REC effects were negative, but, concurrently, their energy intensity effects were positive. These results show that some developing countries recently reduced carbon emissions only by extensively using renewable energy, not by enhancing energy-use efficiency. Finally, some policy implications for reducing CO2 in different countries are recommended.

Unexpected Findings

Purpose The purpose of this study is to assess the nexus between governance and renewable energy consumption in Sub-Saharan Africa (SSA). Design/methodology/approach The focus is on 44 countries in SSA with data from 1996 to 2016. The empirical evidence is based on Tobit regressions. Findings It is apparent from the findings that political and institutional governance are negatively related to the consumption of renewable energy in the sampled countries. The unexpected findings are clarified and policy implications are discussed in the light of sustainable development goals. Originality/value This study extends the extant literature by assessing how political governance (consisting of political stability and “voice and accountability”) and institutional governance (entailing the rule of law and corruption-control) affect the consumption of renewable energy in SSA.

Using the panel vector autoregressive (PVAR) model accompanied by the system-generalized method of moment (System-GMM) approach, this paper investigates the dynamic causality between participation in global value chains (GVCs), renewable energy consumption and carbon dioxide (CO2) emissions throughout 1990–2015 for 172 countries. The results show that participation in GVCs negatively causes renewable energy consumption except for the Middle East and North America (MENA) and sub-Saharan Africa. Second, except for the Asia–Pacific region and globally, participation in GVCs has no causal impact on CO2 emissions, and participation in GVCs has a positive effect on CO2 emissions in the Asia–Pacific region and globally. Third, except for globally and sub-Saharan Africa, CO2 emissions have no causal impact on participation in GVCs; however, CO2 emissions hurt participation in GVCs globally and in the sub-Saharan African region. Forth, renewable energy consumption positively causes participation in GVCs in MENA, while renewable energy consumption does not cause participation in GVCs globally and in other regions. Fifth, there is no causality between CO2 emissions and renewable energy consumption both at the global and regional levels. Several policy implications are proposed and discussed for promoting participation in GVCs and improving the environment.

Abstract This study investigates the relationship between disaggregate components of financial development and CO2 emissions by considering the complicated and multidimensional nature of modern financial systems across the globe. Using panel data for 46 Sub Saharan Africa countries ranging from 1991 to 2016, we adopt the dynamic generalized-method-of moment system (sys-GMM) model to investigate the aforementioned objective of the study. The empirical results show that the development of financial market and its sub-measures such as financial market access, depth and efficiency further raise CO2 emissions in the region. The similar impact is found for the development of financial institution and its sub-measures. However, the development of financial market has a smaller impact on CO2 emissions compared to the development of financial institution. The results further reveal that renewable energy consumption reduces CO2 emissions significantly. An increasing role of financial markets complement renewable energy to improve the quality of the environment. The study also reveal that the relationships among these variables and CO2 emissions vary across countries due to different level of economic development. The policy implications are also discussed in the current study.
