Sub-Saharan Africa (SSA) faces growing pressure to align economic progress with environmental sustainability, as the region contends with climate stress, industrial expansion, and resource-driven growth. Yet, there remains a limited understanding of the combined influence of clean energy, digitalization, FDI, and industrial development on the region's sustainable transition. Accordingly, this study explores the association between clean energy usage, foreign direct investment (FDI), economic growth, digitalization, industrialization, urbanization, and environmental sustainability across 38 SSA countries from 2001 to 2020. Drawing on econometric techniques-including the pooled mean group estimator and method of moments quantile regression-the analysis affirms the transformative potential of renewable energy, which significantly reduces both ecological footprints and environmental pollution. FDI demonstrates dual effects while fostering technological improvements, yet it amplifies ecological footprints through resource-intensive investments. In addition, economic growth is consistently related to increased emissions and ecological impact. Strikingly, digitalization proposes promising pathways for sustainability, while industrialization and urbanization exacerbate environmental challenges. The quantile regression results reveal that the magnitude of these effects varies across different levels of environmental impact, and the Dumitrescu-Hurlin panel causality test affirms bidirectional causalities in at least one cross-section. Considering these findings, sustainable development in SSA requires prioritizing renewable energy adoption, regulating FDI to align with environmental goals, integrating sustainability into economic and industrial policies, and expanding digitalization for smarter resource management.
