ABSTRACT

The rising trend in carbon dioxide emissions has implications on economic livelihoods through global warming and climate change. Attaining lower carbon dioxide emissions is therefore crucial for the realization of the sustainable development goals. South Africa happens to be one of the leading countries in ICT and transport infrastructure in the sub-Saharan African region. Oppossing arguments on how ICT and tranport services affect carbon dioxide emissions exist. However, their effects on the rising trend in carbon emissions in the country has not received much empirical attention. The study analyses the role ICTs and the transportation sector play in the carbon dioxide emissions of South Africa. Regression analysis of data for the 1989-2018 period shows mobile adoption, internet usage, and telephone usage increases carbon dioxide emissions while transportation services in the country helps reduce carbon dioxide emissions. Income positively affects carbon dioxide emissions while urbanization has negative effects. Implications from the findings include the urgent need to have electricity that power ICT devices and equipment be generated from renewable and sustainable sources rather than from heavy polluting sources.
