Emissions of nitrogen oxides (NOx)

Groups: 
  • Passenger Car
Category: 
  • Nitrogen oxides (NOx)

Basic

Requirements and Criteria Type: 
  • Technical Specification (Requirement Specifications)

Main Objective: 

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

Requirement Specification: 

In mixed driving, the vehicle should emit a maximum of 35 mg NOx/km.

Documentation of the Requirement Specification: 

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

The buyer can also check the "Environmental and energy labelling for new cars" label per car model. All dealers are required to have a label that describes the car's environmental and energy properties.

Information about the Requirement Specification: 

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 the emissions values for petrol cars.

Use the "Environmental and energy labelling for new cars" label, which provides information about CO2 and NOx emissions.

Requirements and Criteria Type: 
  • Technical Specification (Requirement Specifications)

Main Objective: 

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

Requirement Specification: 

The vehicle must emit 0 g NOx/km

In other words, the vehicle must be a zero-emissions vehicle (electric or hydrogen vehicle).

Documentation of the Requirement Specification: 

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

The buyer can also check the "Environmental and energy labelling for new cars" label per car model. All dealers are required to have a label that describes the car's environmental and energy properties.

Information about the Requirement Specification: 

Use of the requirement requires the buyer to carry out a market analysis prior to the procurement to secure a sufficient number of tenders. This can be done, for example, through a dialogue with the market or innovative procurement methods. There must be a sufficient number of vehicles on the market that satisfy the technical requirements for the vehicle to ensure genuine competition.

Use of the requirement assumes that the vehicles (first and foremost electric cars) fulfil the needs of the user. For example, it is important to assess needs with respect to range, tow bar and four-wheel drive. The necessary filling and charging structure must also be available for the criterion to be used.

Use the "Environmental and energy labelling for new cars" label, which provides information about CO2 and NOx emissions.
