Abstract: The"dual carbon"goal is a major strategic decision put forward by the Chinese government, that is, to achieve carbon peak and carbon neutrality to cope with the global climate change challenge.As a pillar industry of the national economy, the construction industry accounts for a relatively large proportion of carbon emissions, so promoting the green and low-carbon development of the construction industry is one of the important ways to achieve the "double carbon" goal.As a new type of construction, prefabricated building has the characteristics of high efficiency, energy saving and environmental protection, and is one of the important directions of green and low-carbon development.
