CO2 reduction technologies for the European car and van fleet, a 2025–2030 assessment

Finds that for cars, the cost for meeting a 2025 target value of 70 g/km (as measured in the New European Driving Cycle - NEDC) is between 250 and 500 euros higher than would be the case in a footprint-based CO2 target system. When the European Union (EU) introduced its first set of mandatory new vehicle CO2 standards in 2009, for passenger cars, and 2011, for light commercial vehicles, vehicle mass was chosen as a utility parameter. Using mass as the normalizing parameter allows heavier vehicles to emit more CO2 and consume more fuel than lighter vehicles. As a result, the current EU CO2 target system offers little incentive to reduce the mass of vehicles: the lighter a manufacturer’s fleet, the lower its assigned CO2 target. If a manufacturer reduces the mass of its vehicles, it must then also achieve a lower g/km target. This eliminates most of the manufacturer’s weight reduction advantage and puts mass reduction at a competitive disadvantage compared to other CO2 saving technologies.
