提取和制造建筑材料产生的温室气体排放通常被称为“隐含碳”，是在建筑物被占用之前产生的，对实现全球气候目标的重要性比通常认为的要大。为了激励减少隐含碳，我们需要更好的数据和既定的基准。虽然生命周期评估（LCA）方法已被用于分析单个建筑物，但对建筑物隐含碳的数量级和变化范围尚未达成一致的理解。为了解决这一知识差距，最大的已知建筑隐含碳数据库进行了编译，规范化和分析。除了确定隐含碳值的范围外，本研究还确定了不确定性的来源，并提出了推进隐含碳基准实践的策略。
Greenhouse gas emissions from extracting and manufacturing building materials, often termed “embodied carbon,” are produced before buildings are occupied and are more critical to meeting global climate targets than commonly assumed. In order to motivate reductions in embodied carbon, we need better data and established benchmarks. Although Life Cycle Assessment (LCA) methods have been used to analyze individual buildings, there has not been an agreed-upon understanding of the order magnitude and range of variation of the embodied carbon of buildings. In order to address this knowledge gap, the largest known database of building embodied carbon was compiled, normalized, and analyzed. In addition to establishing the range of embodied carbon values, this research identified sources of uncertainty and proposed strategies to advance embodied carbon benchmarking practice.
