Vehicles are least fuel efficient and most polluting at the start - TopicsExpress



          

Vehicles are least fuel efficient and most polluting at the start of trips and on short trips. One reason for this is that catalytic converters (which reduce air pollution emissions) do not operate properly until they have warmed up. Trips of less than five kilometres generally do not allow the engine to reach its peak operating temperature. Plan to do a number of errands in one trip rather than several trips and save both time and fuel. Try to avoid short vehicle trips by walking or cycling. This will save over a quarter of a kilogram of greenhouse gas emissions per kilometre of vehicle driving it replaces, as well as give you healthy exercise.
