The study adopted threshold regression techniques to estimate the cross-section data spanning 2017 to 2021. It hypothesized that internet users affect CO2 emission between countries and this would vary depending on the level of population. Countries that have smaller populations may not have the same effect on CO2 emissions as compared to countries with larger populations. The empirical results show that internet users exert a significant influence on CO2 emissions, especially under high threshold regimes. Thus, the larger the population, the higher and more significant will be the impact on CO2 by internet users.
