Research on carbon emission reduction based on responsibility of four participants with consideration of circular economy factors in China

The complex relationship between carbon emissions and economic development has become a global issue. In China, the pressure to reduce carbon emissions is very great because the responsibility of four participants for economic activities has not been able to break away from the linear economic model of 'produce-consume-discard'. In this paper, four categories of participants, namely extractors/producers, manufacturers, consumers and recyclers, are classified according to the life cycle framework, and the impact of their activities on carbon emission reduction is analysed taking into account circular economy factors. The results of the study show that during the rapid development of China's economy from 2005 to 2021, there is a significant correlation between carbon emission reduction and the activity behaviour of the four participants with consideration of circular economy factors. In particular, the activity behaviours of the extractors/producers, manufacturers and consumers have a very strong correlation with the carbon emission reduction. Our findings indicate that China should continue to exert efforts in the existing circular economy model to achieve the double carbon goals.
