摘要
Over the years,the African continent has been importing used gasoline and diesel vehicles including ones that are 10 years old.Such vehicles emit carbon dioxide,which is the leading cause of greenhouse gases(GHGs)that are driving the climate change.In Rwanda,for example,road transport contributes to 13 percent of the country’s greenhouse emissions,according to the Rwanda Environment Management Authority(REMA).Africa as a developing continent continues to pollute air,partly due to the use of second-hand cars from developed countries.
