Premium Motor Spirit Consumption and Environmental Sustainability in Nigeria

Human activities globally have resulted in environmental degradation, which poses a threat to resource sustainability for the benefit of future generations. Intergovernmental and private organizations have championed the concept of environmental sustainability as a strategy to preserve the environment for intergenerational use. This research employed Linear and Non-linear Autoregressive Distributed Lag or Bounds Test to Co-integration model, incorporating disaggregated energy consumption sources – petroleum motor spirit and hydroelectricity – along with population growth, to investigate the progress of environmental sustainability efforts in Nigeria. The paper analyzed a time series data for Nigeria ranging from 1982 to 2022. The findings indicate that PMS consumption and population growth consumption patterns constitute a significant threat to environmental sustainability in Nigeria, both in the long and short term, whereas hydroelectricity consumption enhances environmental sustainability. It also reveals that the coefficients the decomposed are not statistically significant at 5% threshold.  Policy developers are advised to regularly review and update comprehensive programs that promote the widespread adoption and utilization of renewable energy consumption as a dominant component in the energy mix.
