Time Series Analysis of Carbon Dioxide Emission, Population, Carbon Tax and Energy use in South Africa


  • Rufaro Garidzirai Walter Sisulu University


The nexus among carbon emission, energy use, population and carbon tax cannot be overlooked. Such a relationship plays an important role to environmentalists, economists, policy makers and researchers. Thus, this study investigates the nexus among carbon emission, population, energy use and carbon tax from 1970-2018. The objective of this study sought to establish the link among carbon emission, carbon tax, energy use and population. The objective was achieved using the Autoregressive Distributive Lag model (ARDL) since it gives accurate parameters. The results of the study show that energy use and population growth positively influence carbon dioxide emission, while carbon tax reduces carbon emission. Based on the study's results, the study recommends that South Africa`s government promote the use of clean energy and develop ways to reduce population growth in minimizing carbon emission.
