Governments engage in infrastructural developments across the globe, and the level of success often colligates with institutional quality levels. However, despite the presence of governance, the lack of well‐developed infrastructure has bedevilled sub‐Saharan African (SSA) countries for decades. Therefore, this study investigates the governance‐led infrastructural development hypothesis for the SSA region from an institutional quality perspective towards addressing the infrastructural deficit challenges of the region. A combination of advanced panel econometric techniques was applied to data collected from the African Development Bank, World Bank World Development Indicator, and International Monetary Fund (IMF) to investigate the governance‐led infrastructural development hypothesis in SSA while controlling for financial development, economic growth, and industrialization in the region. The findings show that the interaction of institutional quality measures and governance indicators significantly and positively induces infrastructure in sub‐Saharan Africa (SSA). Additionally, while economic growth and financial development yield no expected significant influence on infrastructural developments, industrialization plays a crucial role, as its spillover effects are not confined to boosting economic growth alone but also to infrastructural transformations. Thus, the provision of policy frameworks by authorities to strengthen institutions and promote good governance is vital for articulating and facilitating infrastructural development plans for SSA.

The motivation of this study stems from the United Nations Sustainable Development Goals on clean and responsible energy consumption, climate change mitigation and sustainable economic growth (UN-SDGs-7, 11, 12 and 13). The present study examines the impact of institutional quality on CO 2 emissions in the presence of the Environmental Kuznets Curve (EKC) framework using data on CO 2 emissions and the six dimensions of institutional quality from the World Governance Indicators (WGI). The current study focuses on selected 30 Sub-Saharan African (SSA) countries over the annual period from 2000 to 2021. The EKC hypothesis revealed CO 2 emissions are substantially reduced by corruption control, regulatory quality, and the rule of law. Findings from the Dumitrescu and Hurlin causality test showed a one-way causality running from CO 2 emissions to industrialization. Similar uni-directional causality is observed between economic growth, and energy consumption. On the other hand, we observed a two-way causality flow from CO 2 emissions to population growth and all indices of institutional quality over the investigated period. These findings indicate that government agencies should efficiently implement acceptable strategies for pollution control and enact public benefit environmental regulations in the form of a healthier climate for the entire population. • We examined the impact of institutional quality on CO 2 emissions in the presence of the Environmental Kuznets Curve (EKC) framework. • 30 Sub-Saharan Africa (SSA) countries are selected for empirical investigation. • We reveal that CO 2 emissions are substantially reduced by corruption control, regulatory quality, and the rule of law. • Meanwhile, one-way causality runs from CO 2 emissions to industrialization. • A two-way causality flow from CO 2 emissions to population growth and all indices of institutional quality are reported.

The prime objective of the study is to examine the institutional affiliation in assessing the nexus between renewable energy and growth by employing a multi-quantitative approach. The dataset includes the Sub-Saharan African countries encapsulating 1990–2020. At first, the cross-sectional dependence (CSD) and slope's homogeneity (SH) tests were employed. Afterward, CIPS and CADF were employed to obtain the dataset's stationarity elements. The Westerlund bootstrap cointegration test consistently employed the long-term institutional affiliations to confirm the cointegration features. Meanwhile, for examining the short- and long-term performance impacts between the variables, we utilized the CS-ARDL approach. Dynamic heterogeneity causation is involved in identifying the flow of causation. Our results reveal positive renewable energy-growth nexus. Conversely, we report a positive impact on institutional affiliation, while a negative moderating impact on the population is reported. Further, institutional quality negatively influences the renewable-energy growth relationship. We proposed that for attaining long-term growth, Sub-Saharan Africa must expand the investment in renewable energy projects, create well-resourced institutions, and determine contingency plans for renewable energy development. Similarly, other emerging states can also monitor the institutional affiliation affect to observe the renewable energy-growth nexus. • Nexus between renewable energy and growth by employing a multi-quantitative approach. • Cross-sectional dependence and slope's homogeneity tests were employed. • Results reveal positive renewable energy-growth nexus. • Positive impact on institutional affiliation and a negative impact on the population. • Institutional quality negatively influences the renewable-energy growth relationship.
