Comment réduire les émissions de CO2 du transport de fret en France ? Évaluation socio-économique de trois politiques publiques

subject

description

France must implement voluntarist policies in order to reduce CO2 emissions, which raises questions regarding the effectiveness of competing options and their costs, for both public finances and society. This paper estimates abatement costs of one ton of CO2 from three scenarios aimed at softening the environmental impacts of freight moved by trucks. Hybrid trucks may generate large CO2 savings (5.7 Mt/year in 2030), at a moderate discounted abatement cost (88 €/t). The option based on natural gas for vehicles leads to a similar abatement cost and to lower environmental gains (3.2 Mt/year in 2030). Whilst inducing small CO2 savings (0.2 Mt/year in 2030), megatrucks present a negative discounted abatement cost (-285 €/t), thus suggesting the existence of one potential double dividend. Latter result is uncertain, however, as stressed by some of the sensitivity tests proposed in this research.
