Nairobi Embakasi area is home to heavy duty vehicles. According to the latest report by the UN Environment Programme UNEP released this week, Africa lags behind in adopting standards on used heavy duty vehicles HDVs. The report shows that the use of heavy duty vehicles for transportation in Africa is on the increase yet their imports remain highly unregulated, the result being importation of old,polluting and unsafe used HDVs.Due to their heavy usage they are cited as highly contributing to pollution levels and affecting air quality. The report recommends better regulation on these imports and proposes use of advanced technologies in transportation such as electric buses and trucks.
