Trucks and buses cleaner than diesel cars

The research group International Council for Clean Transportation (ICCT), reports that heavy-duty vehicles (mainly buses and trucks) tested in Germany and Finland emitted on average about 200 milligrams of NOx per kilometre driven, less than half of the average 500–600 mg/km pumped out in real-world driving by diesel cars that meet the highest Euro 6 standard.

As the buses and trucks have larger engines and burn roughly five time more diesel per kilometre, this means that heavy duty vehicles are ten times better than light-duty diesel vehicles at reducing NOx emissions.
