A globally regionalized method for life cycle impact assessment (LCIA)
IMPACT World+ is a globally regionalized method for life cycle impact assessment (LCIA), integrating multiple state-of-the-art developments as well as damages on water and carbon areas of concern within a consistent LCIA framework. Most of the regional impact categories have been spatially differentiated and all long-term impact categories have been subdivided into shorter-term damage (the first 100 years after the emission) and long-term damage categories.
It is based on a midpoint-damage framework with four distinct complementary viewpoints to present an LCIA profile (see Methodology for more details):
- midpoint impacts,
- damage impacts,
- damages to human health and ecosystem quality,
- damages to the water and carbon areas of concerns (not yet operationalized).
IMPACT World+ enables the practitioner to account for spatial variability and to identify the elementary flows to be regionalized as a priority to increase the discriminating power of LCA.
