Abstract

Previous studies consider ICT a two-edged sword that can harm or benefit the environment. In recent years, ICT penetration has considerably increased in the ASEAN-6 countries and the leaders of ASEAN are willing to bring a digital revolution by increasing ICT infrastructure and reducing trade barriers in the region under the Master Plan of ASEAN Connectivity-2025. Hence, this paper explores the effect of ICT and the recently developed trade globalization index on CO2 emissions in ASEAN-6 countries. The study relies on advanced panel econometric approaches, including Westerlund (2007, 2008) and Pedroni cointegration tests, CUP-FM long-run method, and panel DH causality approach. The results suggest cointegration among variables. The results of CUP-FM indicate that ICT contributes to improving environmental quality by mitigating CO2 emissions. Similarly, trade globalization is also sustainable in the region as it reduces emissions. The results are also confirmed by using the CUP-BC estimator. The findings from the DH causality test unfold causality from ICT and trade globalization index to CO2 emissions. Besides, the long-run estimates reveal the detrimental effect of energy consumption on emissions and the U-shaped association between GDP and emissions. Moreover, unidirectional causality from ICT to trade globalization index and energy consumption indicates that ICT influences trade globalization and energy consumption. Finally, environmental policies in the context of ASEAN are extensively discussed.
