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.
