Implementation path of dual-carbon in Xiguan historical and cultural district of Guangzhou：A case study on changhua street

In the context of ecological civilization construction, cities are the main source of greenhouse gas emissions and thus they are key areas for dual-carbon construction. The dual-carbon community is the basic unit of the dual-carbon city and is essential for the promotion and construction of beautiful China. Guangzhou, as a historical and cultural city, is actively exploring the micro-renewal path of historical and cultural neighborhoods. In this paper we explore the micro-renewal process of the dual-carbon community and the Guangzhou Xiguan historical and cultural district, as well as their mutual relationship. In particular, we take the historical and cultural district of Guangzhou Xiguan Changhua Street as an example and explore its carbon emission characteristics based on the Intergovernmental Panel on Climate Change (IPCC) inventory compilation method. The carbon emission of this community in 2022 was determined as 3774670 kg, indicating the characteristics of low carbon emissions per capita but high energy consumption. Changhua Street provides a dual-carbon micro-renewal strategy and suggests a dual-carbon implementation path for the Guangzhou Xiguan historical and cultural district in the micro-renewal process.
