课程名称：生命周期评估（Life Cycle Assessment） 课程概述：本课程将介绍生命周期评估（LCA）方法论，这是一种评估产品和系统在整个生命周期内（从摇篮到坟墓）的环境影响的工具。在讨论了定量LCA与其他评估工具的潜力和局限性后，我们将详细阐述并实践LCA的各个阶段。 课程大纲： 1. **面向产品的环境评估：引入LCA** - 本周探讨产品在整个生命周期内的可持续性表现，分析我们日常接触的大量化学产品，识别进行LCA的必要性及其相较于其他环境工具的动机。目标和系统定义阶段明确研究的目标和范围，包括产品功能、功能单位和产品系统及其边界。 2. **LCA目标定义** - 重复以上内容，强调LCA对产品生命周期全程的可持续性评估。 3. **生命周期清单第1部分** - 生命周期清单是第二阶段，量化穿过系统边界的各种资源提取和物质排放。学习如何构建生命周期清单并确定从摇篮到门的累积基本流。建立多个产品的能量和CO2平衡，识别生命周期中的主要阶段，并提供现有数据库概述。 4. **生命周期清单第2部分** - 引入两个特别重要的话题：共产品之间的排放分配以及利用投入-产出分配来补充过程LCA的方法。 5. **生命周期影响评估** - LCA的第三阶段。使用清单数据确定其环境影响并比较不同类型的影响。介绍LCIA原则和框架，并详细说明使用Impact World+方法的每个LCIA步骤。 6. **LCA解释** - 指导您解读结果，实施LCA于SIMAPRO软件，并对产品进行环境分类。讨论检查LCA结果的策略，以识别和讨论生命周期影响评估结果中的主要不确定性，并进行SIMAPRO的教程练习。 通过本课程，您将深入理解生命周期评估的原则和实践，掌握其在可持续产品设计中的应用。
Name:Product-Oriented environmental assessment : Introduction to LCA
Description:This week we take a look at the sustainability performance of products over their entire life cycle, from cradle to cradle. After analyzing the large number of products-chemicals we are in daily contact with, we identify the need for LCA, learn about the motivations to conduct LCAs versus other environmental tools. The goals and system definition step defines the goal and scope of the study, including the product function, functional unit, and the product system and its boundaries
Name:LCA Goal Definition
Description:This week we take a look at the sustainability performance of products over their entire life cycle, from cradle to cradle. After analyzing the large number of products-chemicals we are in daily contact with, we identify the need for LCA, learn about the motivations to conduct LCAs versus other environmental tools. The goals and system definition step defines the goal and scope of the study, including the product function, functional unit, and the product system and its boundaries
Name:Life Cycle Inventory Part 1
Description:The Life Cycle Inventory, the second LCA phase, quantifies the inventory of the various elementary flows of resource extractions and substance emissions crossing the system boundary. We first learn how to build the life cycle inventory and determine aggregated elementary flows from cradle to gate. We then establish the energy and CO2 balance for several products, identifying the dominant stages in the life cycle. This module then provide an overview of existing databases, describes in further detail the widespread ecoinvent database, illustrating the inventory via a simple car example.
Name:Life Cycle Inventory Part 2
Description:The chapter finally introduces us to two special topics of importance: the allocation of emission between co-products and the possibilities offered by Input-output allocation to complement the process LCA approach developed in detail in this chapter.
Name:Life Cycle Impact Assessment
Description:The life cycle impact assessment (LCIA) is the third phase of an LCA. It use the inventory data to determine their environmental impacts and compare different types of impacts. The impact assessment methods are simple to apply, though their development can be relatively complex. After an introduction to LCIA and various environmental impacts, we first present the LCIA principles and framework. The module then details and illustrates using the Impact World+ method each LCIA step, i.e. a) the classification of emissions into different impact categories, b) the characterization of midpoint impacts, c) the damage (end point) characterization and the optional d) normalization and e) weighting steps. The module finishes by an overview of the existing LCIA methods and the present research efforts to arrive to a global consensus method.
Name:LCA Interpretation
Description:This chapter aims to guide you in the interpretation of results, in the implementation of an LCA in the SIMAPRO software and in the environmental classification of products. After describing the main interpretation principles, we illustrate the interpretation steps using an example of desktop versus laptop computers. We then discuss strategies to check LCA results, and identify and discuss the main uncertainties in life cycle impact assessment results and illustrate it with the hands drying example. We then perform a SIMAPRO tutorial exercise, implementing the hand drying example in SIMAPRO. We finally discuss a simplified product classification and provide rules for sustainable design of products, also looking at reuse,recycling and (e-)waste strategies.
This course will introduce you to Life Cycle Assessment (LCA ) methodology, a tool to assess the environmental impact of products and systems over the whole product life cycle, from cradle to grave. After a discussion of the potentials and limitations of quantitative LCA compared to other assessment tools, we will detail and practice each of the LCA phases. 1) The goals and system definition phase defines the goal and scope of the study, including the product function, functional unit, and the
