Emissions of nitrogen oxides (NOx)

Groups: 
  • Light Commercial Van
Category: 
  • Nitrogen oxides (NOx)

Basic

Requirements and Criteria Type: 
  • Award Criteria

Main Objective: 

The main purpose of the environmental criterion is to reduce the quantity of nitrogen oxides (NOx) originating from exhaust emissions.

Formulation of the Award Criteria: 

Tendered commercial vehicles that emit less than 76 mg NOx/km in mixed driving will be awarded points on a scale of 0-10 where 10 points is the best.

Documentation of the Award Criteria: 

NOx emissions will be assessed based on the information in the Norwegian Public Roads Administration's "New Vehicle Chooser".

Information about the Award Criteria: 

The payload is the load a vehicle can carry after the vehicle's own weight has been deducted.

The emissions value in grams of NOx per kilometre of mixed driving for light commercial vehicles is calculated using a special test method in the EU. The driving cycle used, the New European Driving Cycle (NEDC), consists of two parts: the urban cycle (urban driving) and the extra urban cycle (country road driving). The first part provides the emissions value for urban driving g/km and the second provides the value for country road driving in g/km. The value for mixed driving is obtained by weighting the urban and country road driving values.

NOx emissions are somewhat lower for petrol cars than diesel cars. This requirement is based on emissions values for diesel vehicles since this category dominates the commercial vehicles segment.

The criterion's weighting must be assessed in relation to the organisation's overarching climate and environmental objectives. It is important that the buyer sets a requirement of 75 mg or 90 mg NOx/km, respectively.

Difi's power output meter can be used to show the climate and environmental effects of the selected requirement and criterion in a given reference scenario.
