The relationship between CO2 and sulphur emissions with income: an alternative explanation to the environmental Kuznets curve hypothesis

This analysis studies the role of those factors that are exogenous to the environmental Kuznets curve (EKC) model in causing a weakening in the correlation between GDP per capita and emissions (CO2 and sulphur). The aim is to advance within the EKC research by scrutinizing both the historical experience of individual countries and the common features shared by those countries which have managed to reduce emissions (CO2 and sulphur) whilst at the same time increasing GDP income levels. For this purpose, a graphic analysis is carried out.
