Overview of implications, targets and technical paths of carbon neutrality in building sector

In recent years, the global warming caused by greenhouse gas emissions has become more and more serious. In China, the carbon emissions in the construction and operation phase of building sector account for about 42% of the whole society’s carbon emissions. Therefore, the formulation of reasonable building emission reduction targets and policies has an important impact on the realization of China’s 2060 carbon neutrality. In order to promote the building carbon emission reduction work in China, this paper summarizes the implications of key terms related to carbon peaking and carbon neutrality in the building sector at home and abroad and the concepts related to low-carbon building and zero-carbon building, analyses the carbon emission reduction target policies and implementation technical paths in the building sector of some developed countries such as the United Kingdom, Canada, Singapore, etc., and summarizes China’s existing policies related to emission reduction work in the building sector and puts forward some suggestions. It aims to help the formulation of China’s building emission reduction policy and the early realization of the carbon peaking and carbon neutrality targets in the building sector.
