In the era of stock development, urban renewal has become a key variable affecting the process of carbon peak and carbon neutralization of international cities. As a first-tier city in the world, Beijing has a large backlog of community renewal needs. Sustainable community construction is not only an important support to promote green urban renewal, but also the only way to explore low-carbon urbanization. Emergy analysis, as an internationally recognized evaluation method, can comprehensively evaluate the behavior of research systems. In this study, the concept and method of emergy analysis were introduced into community renewal. Taking 36 community units in Long ZeYuan sub-district, Beijing as the research object, the emergy system map was drawn, the index system was constructed, and the social benefits, economic benefits and environmental benefits of the sustainable development of the community were directly quantified, and carry out targeted sustainable design research through quantitative results. The results show that each community is in the consumption stage of non-renewable resources, which also leads to the limitation of the sustainable development capacity of the whole street in the future. Through the in-depth analysis of the community emergy calculation results, it provides a theoretical basis and development ideas for the follow-up green renewal.
