摘要：Many energy-climate policies throughout the world have made net-zero CO2 emissions an explicit goal. To achieve this aim, high-income countries must dramatically reduce their emissions while also obviating large increase in emissions in lower and low economies. However, most studies concentrate on emissions reductions in high income countries, with little attention paid to lower and low economies. The present study analyses the spillover effect of CO2, effects of exports, and energy usage on CO2 emissions in Africa using the dynamic spatial Durbin model. The Hausman test was again performed to determine the choice between the random effects and the fixed effects. The results indicated the existence of spatial spillover effect of CO2emissions among some countries in Africa. The findings suggest that increasing both exports of goods and energy consumption in a focal country, turns to increase the country’s own CO2 emissions and also increases the emissions of its adjacent countries. Comparing the direct effect from the dynamic SDM effects to the SDM effects revealed that exports of goods a variation of 0.085%. The results further confirmed an inverted U-shaped between emissions of CO2 and GDP. Finally, expotrs and energy consumption have a positive and significant total effects on CO2 emissions. Based on the findings obtained, a set policies implications was suggested.
