1、目标与范围定义(Goal and Scope Definition) (1)目标定义:首先,需要明确为何进行LCA以及结果将如何使用。这可能包括改进产品设计、支持市场营销声明、指导政策制定或者提供消费者信息等。目标定义还应该说明对哪些利益相关方报告和他们的信息需求。 (2)功能单位:一个衡量标准,所有数据收集和影响评估都围绕它展开,例如...
Goal and scope definition As depicted in Fig. 1, the analysis was divided into two stages. In the first stage, the LCI for cell production was compiled using 1 unit (1 cell unit = 1p) as the functional unit (FU). The material and energy flows for infrastructure assembly were then...
As shown for the electricity sector, version 2 had a European perspective even for datasets with supposedly global scope, whereas version 3 includes both local and global supply chains. Through the introduction of the global activity coverage, version 3 has thus made an important step towards ...
At level 1 few differences exist: both tools use essentially the same fate and effect models, including their coefficients and data. At level 2 distinctive differences emerge: regional or life-cycle perspective, emission pulses or fluxes, scope of chemicals and types of impacts, use of ...
datasets cover the same scope. Therefore, the influence of data or systematic changes can be identified more easily. The draw- back is, of course, that such comparisons cannot speak for the whole database. In order to implement the matched sample approach, func- tionally identical processes ne...
目标与范围定义(Goal and Scope Definition):明确LCA的目标、研究范围和深度,以及所需的数据详细程度。 生命周期清单分析(Life Cycle Inventory, LCI):收集和计算产品系统输入(如原材料、能源)和输出(如废物、排放)的数据。这是LCA研究的核心环节,也是研究最成熟的一个阶段。

Environmental, 2006) that define the following phases: 1) Goal and scope definition; 2) Life Cycle Inventory (LCI) analysis; 3) Life Cycle Impact Assessment (LCIA); 4) Life Cycle Interpretation. In particular, all data collected and used for the LCI were loaded into SimaPro v.8.3 (è-...
break down the consumption among services considering the electricity demand, taking into account the energy needs, the seasonal efficiencies, and the electrical demand for controlled mechanical ventilation, artificial lighting, and vertical transport (services reported by CENED but out of scope of this...
We previously reported that reactivity towards the Suzuki cross-coupling reaction of 3-iodoimidazo[1,2-a]pyridines substituted at C(2) is largely influenced by the nature of this 2-substituent. Hence, with the aim to expand the scope of this coupling process to the 6-position of this ...
