Life Cycle Assessment and Tools

This chapter offers an overview of Life Cycle Assessment (LCA) as a crucial tool for evaluating the environmental impact of products, processes, and systems. The chapter begins by discussing the benefits of using LCA and its potential to inform decision-making processes and identify opportunities for improvement. The chapter then covers the different types of LCA available and provides guidance on how to choose the appropriate type of LCA for a particular study. The steps involved in LCA are presented in detail, including goal and scope definition, inventory analysis, life cycle impact assessment, and interpretation of results. Specific aspects of LCA are also discussed, such as linear model life cycle inventory and inventory modelling. The chapter emphasizes the importance of data availability and integrity, including the temporal, geographic, and technological coverage of datasets and the use of open-source and subscription databases. Additionally, materials inflow and outflow analysis are presented as an essential aspect of LCA. The chapter concludes by highlighting the standards for LCA and Materials Circular Economy (MCE), providing readers with a comprehensive guide to LCA and its role in promoting sustainable practices.
