Core Components of ISO TR 14047 2003
The technical report breaks down the LCIA process into manageable components, offering
clarity on each aspect. While it does not impose strict requirements, it serves as a
valuable reference for best practices.
Impact Category Selection
One of the first steps in environmental performance evaluation is choosing the impact
categories relevant to the product or system under study. ISO TR 14047 2003 advises on
selecting categories that reflect significant environmental concerns associated with the
life cycle stages. Common categories include:
Climate change (global warming potential)
Ozone layer depletion
Photochemical ozone creation (smog formation)
Acidification
Eutrophication
Resource depletion
Human health effects
Selecting the appropriate categories ensures the assessment captures meaningful
environmental trade-offs and prevents “data overload” from irrelevant indicators.
Characterization Models and Factors
After selecting impact categories, the next step is applying characterization models to
convert inventory data into quantified impacts. ISO TR 14047 2003 discusses various
scientific models that relate emissions to potential effects. For example, greenhouse gas
emissions may be converted into carbon dioxide equivalents using global warming
potential factors.
These characterization factors are critical because they standardize different substances
and allow for aggregation within categories. The report emphasizes the importance of
using scientifically sound and regionally relevant models to increase accuracy.
Normalization and Weighting
ISO TR 14047 2003 also elaborates on normalization, which involves comparing impact
category results to a reference value, such as total emissions within a region or per capita
impacts. This step helps contextualize the significance of each impact.
Weighting follows normalization and involves assigning relative importance to various
impact categories based on stakeholder values or policy priorities. While weighting
introduces subjectivity, the report recommends transparency in methods and assumptions
to support informed decision-making.
