Ethiopia ambitious to expand its carbon emission-free transport system Electric vehicles (EVs) are seeing a promising start in Ethiopia, where used automobile imports contribute to the biggest volume of air pollution. For countries like Ethiopia, the benefts of EVs go beyond simply reducing carbon emissions;they can in fact be seen in cutting a sizeable chunk of foreign exchange spending on fuel and used vehicle imports.
