Overview
SIST-TP ISO/TR 14047:2008, titled Environmental management - Life cycle impact assessment - Examples of application of ISO 14042, is an informative standard that delivers practical examples for carrying out a life cycle impact assessment (LCIA) following the methodology set out in ISO 14042. As part of the broader family of ISO 14000 environmental management standards, this technical report is designed to enhance understanding and facilitate the correct implementation of LCIA within the life cycle assessment (LCA) framework. By presenting real-world case studies, the standard illustrates different approaches and best practices in applying LCIA methods, supporting organizations in evaluating and improving the environmental impacts of products, services, or systems.
Key Topics
-
Illustration of LCIA Practice
The document provides a variety of examples showcasing current practices, reflecting key elements of the LCIA phase as specified by ISO 14042.
-
Mandatory and Optional LCIA Elements
Examples address both mandatory LCIA steps-such as selection of impact categories, assignment of inventory results, and calculation of category indicators-and optional elements like normalization, grouping, and weighting of results.
-
Application of Characterization Models
Several scenarios demonstrate how to use different characterization models to translate inventory results into environmental impact indicators for categories such as climate change, acidification, and resource depletion.
-
Data Quality and Interpretation
Some examples highlight techniques for assessing data quality and interpreting LCIA results, supporting more reliable environmental decision-making.
-
Multiple Approaches to LCIA
The standard emphasizes there is no single way to conduct an LCIA and promotes understanding of alternative methodologies that can still conform to ISO guidelines.
Applications
-
Product and Process Environmental Evaluation
Organizations performing life cycle assessments can use this report to better understand and implement the LCIA phase, helping them identify and quantify the environmental impacts of their products or processes.
-
Comparative Environmental Assessments
The examples support users in making meaningful comparisons between alternative products, technologies, or materials-such as comparing the impacts of different gas pipeline materials or refrigerant gases.
-
Supporting Eco-design and Sustainable Choices
By understanding LCIA methodology through practical examples, organizations can make informed decisions in eco-design, product development, and supply chain management to reduce environmental footprints.
-
Training and Capacity Building
Environmental professionals, auditors, and corporate sustainability teams can use the standard as a teaching tool to illustrate LCIA best practices in line with ISO environmental management standards.
