In the background of “carbon emission peak and carbon neutrality”, the coexistence of multiple electricity-carbon policies and markets has brought about the problem of repeated rewards and punishments for the environmental rights and interests of electric power. To solve this problem, this paper proposes a green electricity-Chinese certified emission reduction (CCER) mutual recognition method based on emission reduction equivalence, uniformly assigns the environmental rights and interests of green electricity to the user side, and the building entity is taken as the research object to verify the mutual recognition method. Firstly, according to the difference of emission reduction characteristics, the buildings are divided into mandatory buildings, emission-reducing buildings and zero-carbon buildings, and the building virtual power plant (BVPP) is used as the agent of CCER mutual recognition. Secondly, aiming at the internal CCER distribution problem of BVPP, a distribution method based on Shapley value method is proposed to ensure the fairness and rationality of the distribution. Then, an electricity-carbon double-layer collaborative trading mechanism based on the principle of energy sharing is proposed for the electricity-carbon collaborative decision-making problem faced by the building entity, and a double-layer decision-making model is constructed based on Stackelberg game theory. The model is convex by combining the concept of supply-demand ratio. Finally, the feasibility of the mutual recognition method and the effectiveness of the electricity-carbon double-layer collaborative decision-making mechanism are verified by the case simulation.
