Managing the LCIA (Impact Assessment) Phase of LCA – 2019
This course gives an overview of the life cycle impact assessment (LCIA) phase of LCA studies. The general framework, definitions and concepts will be presented from those of the ISO standards to the present state-of-the art. Practical exercises will focus on how to make appropriate choices when performing the LCIA phase in a study (choice of impact categories, characterisation models, when to apply normalization and/or weighting, relating to stakeholders) and on the differences between current LCIA methods.
- Description of the different mandatory and optional LCIA elements according to ISO 14040/14044 and other impact assessment frameworks.
- Definitions and concepts of LCIA, such as stressors, actual versus potential impacts, impact categories and pathways, environmental mechanisms, classification, fate, exposure, incidence, duration, linearity, steady-state vs. dynamic, marginal cause-effect modelling, thresholds, tipping points, severity, category indicators, midpoint and endpoint characterisation, areas of protection, normalisation, ranking, weighting.
- Selection of impact categories. Stakeholder views on environmental impact categories.
- Example of the impact pathway modelling of a common impact category: Describing the problem and the target, the borderline to inventory, how to handle incomplete inventory data. Correct application of characterisation factors.
- Simplifying LCIA: What characterises an adequate level of modelling?
- The role of normalisation in LCA studies. Methods for weighting: Distance-to-target versus preference-based methods. Advantages and limitations.
- Combinations of impact categories and ready-made LCIA methods: An overview of the most commonly used and most recent LCIA method packages: CML, EcoIndicator, Impact2002+/ImpactWorld+, Stepwise, ReCiPe, LIME, TRACI. Consistency in and between methods, illustrated with case examples.
- Interpretation and presentation of LCIA results, transparency, dealing with stakeholder interests.
- Exercise: Choosing and justifying the choice of an impact assessment method (impact categories, characterisation models, need for normalization and weighting) for a specific application context, applying it to an LCI result, calculating the LCIA result, interpretation and presentation of the result to a group of stakeholders.
