Показать описание
Life cycle impact assessment (LCIA) is the phase of an LCA where the evaluation takes place of the potential environmental impacts stemming from the elementary flows (environmental resources and releases) obtained in the LCI. LCIA consists of the following steps:
1. Selecting of impact categories
2. Classification: assigning the elementary flows to the impact categories
3. Characterisation: modelling potential impacts using conversion factors obtaining an indicator forthe impact category
4. Normalization: expressing potential impacts relative to a reference
5. Grouping: sorting or ranking the impact indicators
6. Weighting: relative weighting of impact categories and evaluation and reporting
