Two-stroke scooter dominant polluter in many cities

Two-stroke scooters are “super-polluters” in developing countries, according to a study from Switzerland.

The study found scooters, proportionate to the amount of fuel consumed, can emit thousands of times more toxic gases than much larger vehicles such as heavy trucks and buses.

Researchers also found an alarmingly high level of the cancer causing compound, benzene, in emissions.

They said restrictions on two-stroke scooters, already implemented in China, could improve air quality in many cities around the globe.
