Assessing the impacts of setting CO2 emission targets on truck manufacturers: A model implementation and application for the EU

The European Commission introduced in 2018, for the first time, CO2emission standards for truck manufacturers, to incite additional reduction in the road transport CO2 emissions; trucks represent the second major contributor to CO2 emissions in the EU road transport. This paper presents a model based analysis which simulates the implementation of such targets in an energy economic framework and assesses the impacts of such standards using the PRIMES-TREMOVE model. We implement the CO2 emission standards on truck manufacturers as CO2 emission constraints on the new vehicle choice module. The proposed method is formulated as a mixed complementarity problem. The analysis reveals a reduction in road transport CO2 emissions and diesel consumption as a result of an uptake of more efficient truck technologies. In particular, LNG trucks are favored because of the lower emission factor of natural gas relative to that of diesel. Implementing progressively ambitious CO2 standards renders diesel trucks more expensive as their energy efficiency potential reaches its technical limit.
