In Uganda, motorcycles known as boda bodas are a key part of the transport system. The country has more than 1.5 million boda bodas on the road, amounting to roughly 70% of all vehicles. Boda bodas are crucial in providing last-mile transport for people and goods on short trips because they can nip through heavy traffic fast. But their exhaust fumes also pollute the air. Gabriel Okello researches air quality and air pollution in Africa, and examined how life would improve if Uganda’s boda bodas all went electric.
