Abstract: The freight transport sector is a critical sector for achieving carbon peak and carbon neutrality targets. However, there are many uncertainties regarding the e-commerce development, promotion speed of low-carbon measures, and freight transport technologies. Existing research lacks considering the multiple uncertainties on the low-carbon technological pathway for freight transport. Consequently, a bottom-up National Energy Technology-Transport (NET-Transport) model is developed based on the principle of cost minimization for optimizing the low-carbon transition pathway of the freight transport. The study comprehensively evaluates the sustainable technological pathway, energy saving and carbon emission reduction of various measures, including shifting to low-carbon transport modes, improving transport energy efficiency and promoting clean energy. Results show that the freight transport demand will reach 24.1–60.5 trillion ton-kilometers by 2060. CO2 emission would peak at 0.8–1.0 billion tons in 2030–2041 if the breakthrough technologies are not developed on a large scale. Carbon neutrality in the freight sector is difficult to achieve by relying on the low-carbon transition of the energy system alone, with 57–555 million tons of remaining CO2 emissions in 2060. The advanced technologies have significant effects on energy saving and emission reduction. The research, development, and application of hydrogen-fueled heavy trucks should be accelerated.
