The proposal of the “dual carbon” goals has posed stringent emission reduction requirements for China’s port logistics industry. As an important energy export hub in the Bohai Rim region, Hebei Province faces significant challenges in reducing carbon emissions from its port logistics sector due to its large total emissions and complex structure, coupled with multiple constraints in its low-carbon transition. This paper first reviews the current status of energy consumption and carbon emissions in Hebei’s port logistics sector. It then identifies five major constraints to low-carbon development: reliance on fossil fuels in the energy structure, uneven coverage of shore power facilities, insufficient depth in the application of green technologies, the need for further improvement in the policy support system, and the necessity to enhance public awareness of low-carbon practices. Based on these findings, the paper proposes collaborative advancement paths from four dimensions—technology, industry, policy, and society—including optimizing carbon reduction technologies, accelerating the energy structure transition, increasing the utilization rate of shore power, improving green finance and carbon trading mechanisms, and strengthening public participation, to construct a support system for low-carbon development in port logistics. The research conclusions can provide references for formulating low-carbon policies for port logistics in Hebei Province and similar regions.
