Pollution havens in high-income emerging nations: Can green energy, financial development and environmental rules change this?

Abstract

This study investigates the role of green energy, financial development, and environmental regulations in addressing pollution havens within high-income emerging economies. While these nations benefit from rapid industrialization, they simultaneously face significant environmental challenges due to lax environmental standards and a tendency to attract pollution-intensive industries. This paper explores whether green energy adoption, financial sector advancements, and stringent environmental policies can mitigate such adverse impacts. Using data spanning from 1995 to 2023 and employing the Cross-Sectionally Augmented Autoregressive Distributed Lag (CS-ARDL) model, we analyze the experiences of BRICS countries—Brazil, Russia, India, China, and South Africa. The findings reveal that green energy adoption consistently correlates with a reduction in CO2 emissions across these nations, with China showing the most substantial improvement. Financial development positively contributes to environmental outcomes, particularly in South Africa, where access to green finance has spurred investments in sustainable projects. Moreover, environmental regulations have the most profound impact in Russia, where stringent policies have led to a measurable decline in pollution. Countries with higher levels of financial development and regulatory rigor also show stronger resilience against the inflow of pollution-intensive industries. The study highlights the critical role of a balanced approach that integrates economic growth with sustainability, suggesting that high-income emerging economies can leverage green energy and financial development, supported by robust policies, to transition away from pollution havens and toward a sustainable growth trajectory. A policy implication from these findings is that governments should prioritize investments in renewable energy and strengthen regulatory frameworks to attract cleaner industries.
