AB  - This study investigates, the relationship between Economic Growth (GDP) and environmental quality (CO<SUB>2</SUB>) in Nigeria. The Environmental Kuznets Curve (EKC) hypothesis is investigated and tested with annual data of CO<SUB>2</SUB>/capita and GDP/capita from 1970-2005. EKC hypothesis postulates a relationship between economic growth and environmental degradation such that in the early stage of economic growth, the rate of environmental depletion would be on the rise and as income rises above some threshold level the magnitude of environmental impacts due to economic activity would begin to fall. The study reveals that there is no causal or long run relationship between carbon emissions/capita and income/capita in Nigeria. Again, the regression line (curve) gotten from regressing CO<SUB>2</SUB> on GDP and its square completely refute the EKC hypothesis in the case of Nigeria. Interestingly, the curve depicts a &#145;U-shaped&#146; rather than an &#145;inverted U-shaped&#146; curve (as suggested by the EKC hypothesis), meaning that with increase in GDP/capita, CO<SUB>2</SUB>/capita first experiences a declining trend then starts rising again.
