2.1 Theoretical basis
Decarbonization theory: decarbonization generally refers to the use of more efficient energy use and social functioning to promote sustainable urban development through technological advances and changes in social systems in the process of socioeconomic development [14]. In this paper, the main study is the decarbonization of rural residential buildings.
Sustainable development theory: is the replacement of used resources with resources of equal or greater value to maintain the world’s productivity without degrading or endangering natural ecosystems. Sustainable development links concerns about the carrying capacity of natural systems to the social, political and economic challenges facing human society. Its development has evolved from academic research to international attention to a broad consensus among major countries around the globe. Sustainable development is a way of organizing society that can endure in the long term and implies taking into account the importance of both the present and the future, such as the conservation of the environment and natural resources, social and economic equity [15, 16].
