Abstract
Green investment has become the most effective option to support the efforts to mitigate worldwide climate change. Due to the efficacy of green investment in tackling climate change and global warming, researchers are searching for the factors that can boost green investment. Therefore, this analysis aims to investigate the efficacy of information and communications technology (ICT) and financial development in promoting green investment in the most polluted economies. The study analyzes aggregate data from the most polluted economies using the 2SLS, GMM, and instrumental variables quantile regression estimators. In addition, we also perform regional analysis by disaggregating the data into four regions: Asia, America, Africa, and Europe. The results reveal that ICT, financial development, financial institutions, and financial markets boost green investment in the most polluted economies. However, the regional analysis confirms the favorable influence of ICT on green investment in all the regions, while financial development boosts green investment in all the regions except Africa; financial institutions and financial market development promote green investment in America and Europe. Therefore, we suggest that policymakers must increase their reliance on ICT and the financial sector while designing a policy to promote green investment.
