Abstract
The rising energy demand for information and communication technology (ICT) devices has piqued the interest of scholars and policymakers. Given that ICT devices are ubiquitous, any attempt to mitigate climate change should address the carbon footprint of the ICT sector. The present study examines the direct impact of ICT on the environment and the indirect impact through interaction with energy consumption, financial development, and globalization in SAARC economies from 2000 to 2020. Using econometric approaches robust to cross-sectional dependence, such as the Driscoll-Kraay estimator and the Dumitrescu-Hurlin causality test, the study found that ICT, renewable energy consumption, and globalization significantly reduce CO2 emission, whereas non-renewable energy consumption and financial development significantly increase emission. However, the interaction between financial development and ICT jointly reduces CO2 emissions. Similarly, renewable energy and globalization reduce emissions from increased ICT usage. The study also confirms the validity of the environmental Kuznets curve hypothesis for ICT diffusion. The causality test indicates bidirectional causality between ICT and CO2 emissions. Results suggest that SAARC economies can safely boost ICT and related applications to minimize emissions. They should also use renewable energy and green innovations in telecommunications to reduce their adverse environmental repercussions.
