Investigating Financial Development and Its Direct and Indirect Environmental Effects in South Africa: Fresh Policy Insights

Results on the connection between financial development and CO2 emissions are presented in contradicting ways in earlier research. In order to solve this conundrum, the Environmental Kuznets Curve (EKC) framework is used in this study to examine both the direct and indirect effects of financial development on environmental degradation. Our empirical analysis is supported by the cutting-edge dynamic ARDL simulations framework for the 1960–2020 time span in South Africa. The estimated results, which are based on five separate financial development indices, corroborate South Africa's claim that the country's financial development prevents pollution. For South Africa, we also confirm the validity of the EKC theory. The results of the indirect channels demonstrate that financial development also lessens the negative impacts of income, energy usage, trade openness, and foreign direct investment (FDI) on pollution emissions. A weak financial structure is also necessary for the viability of the polluted haven hypothesis (PHH), which is examined using trade openness and FDI variables. For each of these variables, PHH vanishes at a particular point in financial development. Last but not least, increased industrial value-added increases pollution emissions, whereas increased technical innovation decreases the former. On the basis of these findings, South Africa should offer financial incentives and tax breaks to attract green FDI and encourage investments that prioritize environmental sustainability. These incentives can include grants, subsidies, and preferential tax rates for FDI projects that align with South Africa's environmental goals. Providing a favourable investment climate for green projects can stimulate sustainable economic growth and attract responsible investors.
