This study examines the impact of Information and Communication Technology (ICT) on carbon dioxide (CO2) emissions in ten net energy-exporting MENA countries from 1994 to 2019. A composite ICT index, developed using the Data Envelopment Analysis (DEA) method, is applied alongside advanced econometric techniques such as Quantile-on-Quantile (QQ) regression, wavelet coherence analysis, and Wavelet Local Multiple Correlation (WLMC). Results reveal that ICT has a significant positive effect on reducing emissions at both low and high quantiles, although the impact varies across countries. While ICT adoption initially correlates with increased emissions due to infrastructure demands, its long-term effect, particularly when integrated with renewable energy practices, is more beneficial for emissions reduction. The findings emphasize the potential of ICT in promoting environmental sustainability in the MENA region and the need for tailored ICT policies.
