新能源重卡生命周期碳减排的影响因素与发展路径研究OA

Heavy-duty trucks are a key link in achieving carbon emission reduction in road freight.The life-cycle carbon reduction benefits of different technology pathways vary significantly,and no single pathway can adequately accommodate diverse transportation scenarios.This paper systematically reviews the policy background and development trends of new energy heavy-duty trucks.From three perspectives—vehicle fuel cycle,vehicle life cycle,and integrated freight network—it summarizes the key parameters and mechanisms influencing carbon reduction of mainstream technology pathways,and assesses the applicability of each pathway in typical scenarios.The findings indicate that fuel decarbonization,powertrain upgrading,and freight network optimization are key influencing parameters for enhancing life-cycle emission reduction;improving refueling infrastructure can enhance the economic substitutability of low-carbon technologies;and tailoring strategies to local conditions—considering both transport scenarios and resource endowments—facilitates the practical deployment of low-carbon heavy-duty trucks.On this basis,policy implications are proposed from four aspects:key technology standards,refueling infrastructure development,differentiated deployment pathways,and demand-side policy incentives,aiming to provide a reference for the low-carbon transition of new energy heavy-duty trucks.
