The Analysis of Energy Consumption and Greenhouse Gas Emissions in Nigeria

The present study examines the short-run relationship between energy consumption and greenhouse gas emissions for Nigeria. Time series data spanning the period 1986-2018 were analyzed using Autoregressive Distributed Lag (ARDL) approach. The bounds test results confirm that there is no long-run relationship between greenhouse gas emissions and energy consumption. The results of short run estimates shows that D(LOGDFOIL(-1)), D(LOGCRUDE(-1)), D(LOGCOAL(-1)) and D(LOGCOAL(-2)) positively and significantly impact on CO2 – carbon dioxide emissions per capita (D(LOGCO2)) while D(LOGMETH(-1)), D(LOGDFOIL(-1)), D(LOGJFUEL(-2)), D(LOGMGAS(-2)) and D(LOGOPPRO(-2)) were found to have a positively significant influence on methane emissions (kt of CO2 equivalent). Furthermore, D(LOGELEC(-1)), D(LOGJFUEL(-1)), D(LOGOGHG(-1)),  D(LOGCRUDE(-1)), D(LOGRFOIL(-1)),  D(LOGCRUDE(-2)), D(LOGDFOIL(-2)), and D(LOGDNGAS(-2)) showed positive and significant relationship with other greenhouse gas emissions (D(LOGOGHG)) such as HFC, PFC and SF6 (thousand metric tons of CO2 equivalent) were used as dependent variable. As such, there is need to decrease power plant emissions and promote a greater use of renewable energy resources in Nigeria.
