In the modern era of globalization, information and telecommunication technologies (ICTs) have become an important factor influencing carbon dioxide (CO₂) emission; however, the specific effect produced by ICTs is still not clear. Therefore, the study examines the nexus between ICTs, foreign direct investment, globalization, and CO₂ emission in 77 developing countries. The novel attribute of this research is the ICTs with financial development and the international trade interaction term. The results of this study are based on the pooled regression and generalized method of moment (GMM) techniques from 1990 to 2016. The subsequent empirical findings are established as follows: first, the ICTs positively contribute to reducing CO₂ emission. Second, globalization significantly increases the CO₂ emission; third; the interaction between ICTs and financial development increases CO₂ emissions, and the moderating effect of ICTs and international trade performs the similar role. Fourth, the empirical finding verifies the presence of the pollution haven hypothesis. Fifth, our robustness tests confirmed that our empirical results were consistent. We suggest that policymakers should be using ICTs as a policy tool to mitigate CO₂ emission and should invite such investments in ICT sectors, which help maintain the environment quality.
