The Generalized Method of Moments and forty-three nations from 2002 to 2021 are the foundation for the empirical evidence. Internet and mobile phone usage are used to gauge ICT, and CO₂ emissions per capita, CO₂ emissions from the usage of liquid fuels and, CO₂ emissions from carbon intensity are utilized as indicators of environmental sustainability. The following conclusions are made: ICT (i.e., mobile phones and the internet) significantly affect CO₂ emissions per capita positively. Second, there is significant relationship between ICT penetration and CO₂ emissions from the usage of liquid fuels with a p-value of 0.031 and 0.018 having a positive co-efficient. Thirdly, a significant relationship exist between ICT and CO₂ emissions from carbon intensity with a p-value of 0.029 and 0.034 having a positive co-efficient. The study also recommends that future research should consider other variables that were neglected in considering the link between ICT and environmental sustainability.enAttribution 4.0 InternationalEmissionICTDissertation
