CO2 from HDV

Technological improvements to reduce CO2 emissions from HDVs will continue. to be developed in several areas including:

Diesel engine efficiency

Turbocharging

Aerodynamics

Hybridisation (even for long-haul)

Efficiency of auxiliaries / components

Heat-recovery

Intelligent systems linking vehicles to navigation data

Light-weighting

CLEPA believes that the CO2 reduction potential of HDVs must be assessed in detail, and that an extrapolation based on existing studies on passenger cars is not possible and the reduction potential could be increased through Intelligent Transport Systems and through other logistic concepts e.g. European Modular Systems (EMS).

It is vital to get the measurement method right. A measurement method that only focuses on the engine or a small selection of points risks not being representative of real-world CO2 emissions from HDVs.

An EU-wide standardised CO2 measurement method will increase transparency in the HDV market and further stimulate competition for efficient HDVs.

Given that total costs of ownership (TCO) and hence efficiency are already a key factor in HDV purchase decisions, a thorough investigation is required to what extent CO2 limitation legislation would be appropriate.

Policymakers can and should support the market penetration of innovative efficiency technologies by improving their TCO, for example through CO2-based taxation and road tolls.
