The energy consumption-environmental quality nexus in BRICS countries: the role of outward foreign direct investment

This paper examines the role of outward foreign direct investment on energy consumption and environmental quality in BRICS from 1990 to 2019. Most of the previous research considered foreign direct investment mainly focused on the environmental impact on the host country effect and ignored the home country effect. Therefore, the current study examines the home country effect of environmental pollution. We use various methodologies like cross-sectional dependence and the Pesaran-Yamagata slope homogeneity for the diagnostic test. After confirming the diagnosis test, we employ second-generation panel unit root tests, which confirms that all elements are stationary at first difference. The pooled mean group (PMG), Westerlund cointegration, two-step generalised method of moments (GMM), panel fully modified ordinary least square (FMOLS), and dynamic ordinary least square (DOLS) model have been used to determine the short-term and long-term association among the variables. The cointegration and PMG results confirm that the short-run and long-run association exists among the considered variables. The results reveal that developing countries produced environmental pollution at the early stage of development and checked in the long run. The study used the STIRPAT model to build an extended carbon dioxide emissions model by incorporating outward FDI, GDP per capita, and technology to achieve our objectives. The empirical results hold up the environmental Kuznets curve hypothesis, implying that outward FDI and energy consumption help expand greener technology to host countries’ environmental improvement in the long run and confirm that an inverted U-shaped linkage exists. Hence, the study suggests that developing countries should pay more attention to sustainable development and technological development that encourages more eco-friendly and environment-friendly technology.
