| Embodied carbon is one of the key metrics that an LCA quantifies, since every step in a product's or building's life cycle generates carbon emissions. Historically, concrete has had high levels of embodied carbon because of the emissions associated with making portland cement. |
隐含碳是LCA量化的关键指标之一，因为产品或建筑生命周期的每个步骤都会产生碳排放。从历史上看，混凝土具有很高的隐含碳，因为制造硅酸盐水泥产生的排放。 |
| Strategies include: reducing the total amount of materials used through sufficiency, circularity, and material-use optimization; purchasing materials locally; selecting materials with lower embodied carbon. |
策略包括：通过充足性、循环性和材料使用优化减少使用的材料总量；本地采购材料；选择隐含碳较低的材料。 |
| Ecological conservation and restoration: Sustainable or regenerative forestry and farming practices can help ensure the lowest possible embodied carbon for plant-based materials while balancing the needs of local ecosystems. |
生态保护与恢复：可持续或再生林业和农业做法可以帮助确保植物基材料的最低隐含碳，同时平衡当地生态系统的需求。 |
