Abstract
Higher education R&D expenditures (HEEXP) are one of the important determinants of economic growth that facilitates science, technology, new ideas, and innovation, but its effect on environmental sustainability remains unexplored. This paper examines the nexus between HEEXP and carbon dioxide emissions (CO2e), followed by control variables such as electricity consumption, foreign direct investment, gross domestic product, and total population for the period 2000Q1-2019Q4. Some of the key results are as follows. First, the present findings confirmed the long-run cointegration among variables. Second, the finding showed significant long-term negative nexus between HEEXP and CO2e. Third, the findings indicated that electricity consumption, foreign direct investment, gross domestic product, and total population are the important factors that intensify the overall situation of CO2e. Fourth, the results indicated that there exist a bi-directional causality between EC and CO2e; FDI and CO2e; GDP and CO2e; POP and CO2e and HEEXP, and CO2e.
