As one of the important tools to promote low-carbon development，the establishment of an implementation effect assessment system is necessary to judge the effectiveness of the carbon label system. The adoption of a suitable method to evaluate the implementation effect of carbon label can influence the design of carbon labels，the formulation of low-carbon policy system and the assessment of whether carbon reduction targets can be achieved. This report constructs the assessment system，applicable conditions and policy implications of carbon label implementation effectiveness from the perspectives of carbon label system design，stakeholder response and economic linkage effects. With interviews，questionnaires and experimental methods，the report analyzes the problems arising from the implementation of carbon label in the electronics and electrical appliances industry in terms of accounting database，policies，enterprises，consumers and third-party certification bodies. And suggestions are made to strengthen the awareness of low-carbon development，enhance the training of low-carbon talents，and actively carry out international cooperation. The future senario of a reasonable and effective carbon label system is envisioned through the concerted efforts of relevant parties from the government，associations，enterprises and consumers.
