Theoretically, population growth is believed to increase greenhouse gas emissions, particularly CO2 emissions through the increase in human activities. Accordingly, this study aimed to investigate this assertion in Nigeria using an autoregressive distributed lag model covering periods from 1971-2000, 1971-2005, and 1971-2010 recursively. The results indicated that population was not a determinant of CO2 emissions in all the three periods in the long run.
