The influence of economic complexity processes and renewable energy on CO2 emissions of BRICS. What about industry 4.0?

This study analyses the relationship between carbon dioxide emissions per capita, economic complexity index, renewable energy, and inward foreign direct investment using panel data for BRICS countries from 1995 to 2020. Empirical results confirm that environmental Kuznets curve is fulfilled, with a positive but decreasing contribution of development on deterioration, point neutrality CO2 can be achieved in long term. In addition, confirm, this case, Pollution Haven Hypothesis, is, set economies chooses apply regulations do not respect environment. The other econometric studies support study, pointing long-run cointegration. unit root tests variance inflation test also stationarity at first difference lack multicollinearity, respectively. Finally, given scarcity empirical studies, adopts an incipient methodology approximate impact technologies associated Industry 4.0 emissions, obtaining evidence their effect deterioration very moderate. suggest that, term, these contribute achieving polluting emissions.
