The study on ambient air pollution and mortality rate in Nigeria is an attempt to evaluate the effect of ambient air pollution proxied by carbon dioxide on non-accidental, cardiovascular and respiratory disease related mortality in Nigeria from 1970-2019. Time series data adopted from World Development Indicators were analyzed using Auto Regressive Distributed Lag Model. Results suggest a positive relationship between CO2 and crude death rate in Nigeria. Thus, the result of ARDL for lnCruder as the dependent variable showed that carbon dioxide emission was positively related to the crude death rate. Consequently, one unit increase in the quantity of carbon dioxide emission increased the death rate by 19% at lag 1, all things being equal. A similar result was obtained for CO2 and life expectancy where carbon dioxide emission was found to have a negative effect on life expectancy. The study concludes that carbon dioxide emission has a negative effect on human health and causes death in human beings. Therefore, further study is recommended on ways of abating carbon dioxide emissions through the use of technologies that generate less carbon dioxide and the adoption of domestic practices that reduce the quantity of CO2 produced in the environment.
