Abstract
This study examines the relationship between
CO2 emissions and life expectancy in Nigeria, employing an
Autoregressive Distributed Lag (ARDL) model to analyse both short-run and
long-run effects. The study utilises data spanning from 1986 to 2020, focusing
on CO2 emissions from different sources—solid, liquid, and gaseous
fuels—alongside economic growth indicators and government health expenditures.
The findings reveal that CO2 emissions from all sources negatively
affect life expectancy in both the short-run and long-run analyses, with
emissions from solid and liquid fuels showing particularly strong adverse
effects. Conversely, the study finds that higher GDP per capita and increased
government health expenditure significantly enhance life expectancy,
acknowledging the critical role of economic development and health funding in
improving public health outcomes. The study confirms the necessity for
comprehensive environmental policies aimed at reducing pollution and promoting
cleaner energy alternatives. Additionally, it highlights the importance of
economic policies that foster growth and health sector investments, suggesting
these as dual avenues for enhancing the well-being and longevity of the
Nigerian population. This paper contributes to the existing literature by
providing empirical evidence of the direct and indirect effects of
environmental and economic factors on public health. It offers valuable
insights for policymakers on the importance of integrated strategies that
address both environmental sustainability and economic development toward
improving life expectancy in developing countries like Nigeria.
