Abstract
The increasing use of information and communication technology (ICT) in this digital era and its interlinkage with other economic and environmental factors have gotten considerable attention from researchers. ICT tools are considered very important in economic activities such as international trade, the financial sector, and foreign direct investment. ICT is also interlinked with innovation and energy consumption. However, ICT with these activities influences ecological footprint, especially in emerging economies such as BRICS (Brazil, Russia, India, China, and South Africa) countries. Therefore, this topic has got considerable attention from researchers and policy makers on the impact of ICT and economic growth activities on environmental quality. Consequently, this study investigates the impact of information and communication technology, renewable energy consumption and innovation on carbon dioxide emission in BRICS countries from 1990 to 2019 using cointegration, generalized least square, and panel corrected standard errors models. The findings show that two ICT indicators, mobile cellular subscription and fixed broadband subscription, negatively affect carbon emission along with economic growth and financial development. Innovation and renewable energy consumption also significantly reduce emission in presence of ICT indicators, while trade openness and fixed telephone subscriptions increase it. In the case of the ICT index model, all variables are positively associated with carbon emission except renewable energy consumption, however, the square and interaction term of all indicators significantly reduce carbon emission and evidence the environmental Kuznets curve hypothesis except trade openness. ICT growth should be considered in the energy sector, innovation, and financial development to enhance environmental quality. The findings of the study have considerable policy implications for the sample countries.
