Diesel Engine

"Compared to a petrol driven car, a diesel car causes slightly higher emissions, primarily of nitric oxides"

Swedish Consumer Agency

"On average, diesel engine vehicles are bigger, heavier and more efficient than petrol vehicles. They are also used more frequently to travel greater distances. As a result, according to data from the NGO Transport and Environment, diesel engines in circulation are, on average, polluting more than petrol engines in terms of CO2 emitted over their life cycle. In general, it can be said that petrol vehicles are on average less polluting than diesel vehicles. They emit less fine particles, and even less CO2 as they are often smaller vehicles used for shorter travels. "
