A heavy mineral oil used as fuel in diesel car engines. Typically more popular than unleaded fuel for fleets due to greater efficiency.
The surcharge placed on diesel-powered company cars, putting them three BIK bands higher than a car emitting the same CO2 following Government concerns that diesels produce more NOx and particulates than equivalent petrol engines. It's due to be abolished in 2015.
Educating company drivers through in-car, online or classroom training to raise awareness on areas including safety and efficient driving.
