The differential impact of export and import trade on carbon dioxide emissions: A comparative analysis between African and European countries

2024-10-17T00:58:04-05:00

This study examines the effects of export and import trade on carbon dioxide (CO2) emissions in 49 African and 37 European countries from 2005-2021 using World Development Indicators (WDI). Export and import trade has a differential effect on CO2 emissions in both Africa and Europe, though African countries generally have lower emissions than European countries with an increasing trend. Trade is crucial in both regions, but the environmental impact remains uncertain. The study emphasized the two-step system generalized method of moments (GMM) and a quadratic function. The results indicate that: 1) Export trade increases CO2 emissions in both regions in the short and long term. 2) Import trade reduces CO2 emissions in Africa in the short and long-term, but has no significant negative long-term impact in Europe except in the short run. 3) There was no evidence of an environmental Kuznets curve (EKC) but a U-shaped relationship between trade and CO2. 4) Early development witnesses the halo effect, which transitions to the pollution haven hypothesis after a turning point in both regions. The study recommends that both regions should adopt environmentally friendly trade policies that should aim at reducing CO2 in the export trade nexus.

Climate change and health outcomes in Sub-Saharan African countries

This paper examines the effect of climate change on health outcomes in sub-Saharan Africa (SSA). Greenhouse gas emission was used as the measure of climate change, while life expectancy rate was used as the measure of health outcomes. This paper's significant contribution is how the interaction of climate change and government effectiveness index influence health outcomes in SSA. We estimated the impact of climate change on health outcomes using the panel system generalized method of moments (GMM) method. Our empirical result show that there is a negative and significant relationship between climate change and life expectancy in the short and long run. In addition, we find that if effective government policy is interacted with climate change, this mutes the negative impact of climate change on health outcomes in SSA. This implies that, with effective government policies targeted toward achieving net zero carbon emission, climate change is not expected to have a significant impact on health outcomes in SSA.
