摘要：The study investigates the direction of causal relationships among emissions, energy consumption and economic growth in Nigeria using annual time series data for the period 1970-2013. The Johansen maximum likelihood cointegration tests indicate an existence of a unique cointegrating vector, and the normalized long run estimates shows that fossil fuel enhances carbon emissions whereas, clean energy source (electricity) mitigate the atmospheric concentration of CO 2 emissions. Similarly, the Wald exogeneity Granger causality test indicates an existence of unidirectional causation running from fossil fuel to CO 2 emissions and GDP per capita. Alternatively, non-fossil energy (electric power) causes more proportionate change in GDP per capita but our result could not establish any causal link between electric power and carbon emissions. Finally, charting a channel towards ensuring sustainable environment and economic development involves a progressive substitutability of clean energy sources for fossil consumption. Keywords: CO 2 emissions, Energy Consumption, Johansen Cointegration, Granger Causality JEL Classifications: C22, O13, Q53
