en عمومى General مقاله اصیل Original Article <div style="text-align: justify;">Background: The need to understand the causes of CO2 emissions has prompted the formulation of strategies to prevent global warming. Therefore, the purpose of the study was to determine the input variable that is the most influential in contributing to CO2 emissions and at the same time to forecast the effect of a shock in macroeconomic variables on CO2 emissions for 6 leading African countries over the period of 1970 to 2019.<br> Methods: In this study, the statistical methods of impulse response function and variance decomposition techniques of analysis were used.<br> Results: A one-standard-deviation rise in economic growth leads to an increase in CO2 emissions. A shifts in the square of economic growth increased CO2 emissions, the shock was smaller than that of economic growth. This confirms the theory of EKC in Africa. A shocks to FDI had a positive influence on CO2 emissions. A one standard deviation shock in financial development had an instantaneous positive impact on CO2 emissions. FDI had a greater effect than other factors in explaining CO2 emissions over the short and medium term. In the long run, economic growth contributes the most to CO2 emissions among the explanatory variables.<br> Conclusion: The findings of the study can be used as a reference for international organizations and environmental policymakers in forecasting climate change and assisting in policy decision-making. Africa must boost economic growth through industrial, agricultural, and energy usage patterns and integrate innovation, research, and technology advances into their developmental agenda to fulfil sustainable development goals while lowering CO2 emissions and their consequences.</div> Economic development, Climate change, Impulse response function, Variance decomposition, Africa 223 232 http://ehemj.com/browse.php?a_code=A-10-1-249&slc_lang=en&sid=1 Aminu Hassan Jakada aminu.jakada@fud.edu.ng 100319475328460010806 100319475328460010806 Yes Corresponding author: Department of Economics and Development Studies, Federal University Dutse, Jigawa State, Nigeria Suraya Mahmood surayamahmood@unisza.edu.my 100319475328460010807 100319475328460010807 No Faculty of Business and Management, Universiti Sultan Zainal Abidin, Terengganu, Malaysia Ali Umar Ahmad umarahali204019@gmail.com 100319475328460010808 100319475328460010808 No Faculty of Maritime Management, Universiti Malaysia Terengganu, Malaysia Ibrahim Garba Muhammad ibrahimgeem@gmail.com 100319475328460010809 100319475328460010809 No Department of Business Administration, Bayero University Kano, Kano Nigeria Ismail Aliyu Danmaraya ismail.danmaraya@aun.edu.ng 100319475328460010810 100319475328460010810 No Department of Economics, American University of Nigeria, Adamawa State, Nigeria Nura Sani Yahaya nurasaniyahaya@gmail.com 100319475328460010811 100319475328460010811 No Kano State College of Education and Preliminary studies, Kano, Nigeria
