Presently, global warming becomes a scientifically proven problem. Where, the global warming contributes to increase the Earth’s average temperature, because of the release of the Greenhouse Gases (GHG) into the atmosphere, in particular the gas Carbon Dioxide (CO2). This empirical paper focuses on the investigation of the relationship between per capita Carbon Dioxide (CO2) emissions and per capita Gross Domestic Product (GDP) in Sweden. The study tests whether an Environmental Kuznets Curve (EKC) relationship holds for Sweden, covering a time series over the period 1840-2010. The study employs the Ordinary Least Squares (OLS) as an econometrics method to test three different models of the EKC. Our findings suggest that there is an existence of the common inverted U-shaped of EKC in Sweden and the estimated turning point (TP) is about 16 500 US$ per capita GDP.
