Climate change mitigation is a recurrent consciousness topic among society and policymakers. Actions are being adopted to face this crucial environmental challenge, with a rising concern with a big impact on the building sector. Construction materials have a high carbon footprint as well as an energy-intensive activity. To measure the environmental damage and effects, life cycle assessment (LCA) is the methodology most widespread. However, the LCA methodology itself and the assumptions done to carry it out leads to a generalized burden to compare the case studies outcomes. LCA method and for instance geographical location are incompatibilities also revealed in embodied energy and embodied carbon assessments. Urgent actions are needed to clarify the confusions arisen in the research, considering a detailed study on the embodied energy and embodied carbon values. From a material level point of view, this paper aims to illustrate the chronological overview of embodied energy and embodied carbon through keywords analysis. Moreover, to support and corroborate the analysis, an organized summary of the literature data is presented, reporting the range of embodied energy and embodied carbon values up to now. This systematic analysis evidences the lack of standardization and disagreement regarding the assessment of coefficients, database source, and boundary system used in the methodology assessment.

结构建筑材料的隐含能源和隐含碳：通过文献图分析的全球进展和障碍


减缓气候变化是社会和政策制定者经常关注的话题。人们正在采取行动应对这一严峻的环境挑战，人们越来越担心这会对建筑行业产生重大影响。建筑材料具有高碳足迹以及能源密集型活动。为了衡量环境损害和影响，生命周期评估（LCA）是最广泛使用的方法。然而，LCA 方法本身以及为执行该方法所做的假设会导致比较案例研究结果的普遍负担。 LCA 方法和地理位置等不相容性也在隐含能源和隐含碳评估中显现出来。考虑到对隐含能源和隐含碳值的详细研究，需要采取紧急行动来澄清研究中出现的混乱。本文旨在从物质层面出发，通过关键词分析来阐述隐含能源和隐含碳的时间脉络。此外，为了支持和证实分析，对文献数据进行了有组织的总结，报告了迄今为止的隐含能源和隐含碳值的范围。这种系统分析证明了方法评估中使用的系数评估、数据库来源和边界系统缺乏标准化和分歧。
