Eco-innovative technologies reducing CO2 emissions of light-duty vehicles: evaluation of interactions
Article 11 of Regulation (EU) 2019/631 setting CO2 emission performance standards for new passenger cars and for new vans provides a possibility for manufacturers of passenger cars and light commercial vehicles to take into account CO2 savings from innovative technologies, which cannot be fully quantified when using the standard emission test procedure (currently WLTP) for meeting their specific CO2 emission targets. Such ’eco-innovations’ have to be approved by the Commission on the basis of an application by one or more vehicle manufacturers and/or component suppliers.
If more than one technology is installed on a vehicle, the combined CO2 savings may be less than the sum of the individual savings because the functioning of the one has an effect on the other. This effect is referred to as an ‘interaction’ and may be presented as a percentage of the sum of the individual CO2 savings. Where such an interaction cannot be ruled out, the vehicle manufacturer shall indicate any form of interaction both at the stage of the application submission and at the stage of type approval, providing a report to the independent and certified body to quantify it.
The report shows how to calculate the CO2 savings applying two analytical methods or, as an alternative to the detailed calculation method, the report introduces the use of pre-defined interaction reduction coefficients (PIRCs).
