With the gradual progress of China’s“dual carbon”work, the carbon emission verification of residents has become increasingly important. In order to solve the problems of large analysis granularity and low verification accuracy in resident carbon emission verification, a resident carbon emission verification method based on carbon flow tracking is proposed. First, smart home is used to collect the energy consumption of residents’roof photovoltaic, energy storage and various energy consuming devices. Second, carbon flow tracking technology is adopted to realize the positive tracking of carbon emissions of household energy equipment, the reverse tracking of carbon emissions of roof photovoltaic and reverse power storage, and the two-way carbon flow allocation of loss. On this basis, the carbon emissions of residents are verified. Finally, a case study is conducted in a city in southern China, and the results show that：the proposed method can effectively improve the particle size of residents’carbon emission verification and the accuracy of carbon emission verification.
