Green construction embodies the concrete implementation of green development concepts withinthe field of engineering and construction, serving as a pivotal means to achieve China’ s ‘dual carbon’targets and high⁃quality economic growth. This paper introduces the fundamental concept and richconnotations of green construction, following which it elucidates the current state of ten key greenconstruction technologies organized under four main developmental directions, low⁃carbonization,prefabrication, intelligentization, and lean construction. These includes green low⁃carbon designtechniques, eco⁃friendly building materials, resource recycling, and renovation of existing buildings.Through questionnaire surveys and expert interviews, the study analyzes common challenges faced byChina in the development of green construction technologies across areas, such as technological research,resource allocation, collaborative systems. Based on these findings, this paper offers targeted policyrecommendations including accelerating the R & D and promotion of key technologies, increasing policyand financial support, and strengthening the theoretical and technical framework for green construction.
