Assessing the nexus of gross national expenditure, energy consumption, and information & communications technology toward the sustainable environment: Evidence from advanced economies

The quantity of carbon dioxide in the atmosphere rises yearly because human activities emit more of it than the earth's natural processes can absorb. The overall carbon dioxide emissions continue to rise due to development demands. In a panel setting, this paper investigates the link dynamics between gross national spending, energy consumption, information and communications technology, and CO2 emissions in advanced nations from 2000 to 2020. We employ quantitative sequential approaches, such as DOLS, unit root test, and cointegration techniques, to ensure the coherence and feasibility of the study. Both versions of the estimators show statistically significant effects of gross national expenditure, energy consumption, and Information & Communications Technology on CO2 emissions. The findings of this paper show that there is a long‐run relationship between independent and dependent variables. The study also shows that rising exports of ICT services, energy consumption, and population need environmental protection and highlight the necessity for environmental regulations that can minimize emissions throughout the country's expansion. Even in advanced nations, climate vulnerability is not automatically reduced by development status but is instead reduced by the right sort of growth.
