The objective of this study is to investigate the complex relationship between key economic indicators and their impact on carbon dioxide emissions (CO2) within the G20 nations. The study utilizes advanced econometric techniques, including co-integration, PMG, LSDV, dynamic and fully modified OLS, to analyze the relationships between Gross Domestic Product (GDP), industrialization, population, urbanization, Foreign Direct Investment (FDI), and CO2 emissions. The findings indicate that economic growth, as measured by GDP, is positively associated with higher levels of CO2 emissions. Similarly, industrial production shows a positive correlation with CO2 emissions. Population growth and FDI also contribute to increased CO2 emissions. The analysis further reveals bidirectional Granger causal relationships among CO2 emissions, urbanization, and population growth, as well as four unidirectional causal linkages connecting GDP, GDP Share (GDPS), Industrial Value-Added (IVA), and FDI to CO2 emissions. Overall, the study provides insights into how economic development choices within the G20 nations influence carbon emissions, aiding in the formulation of informed policy decisions for sustainability.
