TL;DR: A review of recent developments of LCA methods, focusing on some areas where there has been an intense methodological development during the last years, and some of the emerging issues.

TL;DR: Usetox as discussed by the authors is a scientific consensus model that contains only the most influential model elements and is used to calculate CFs for several thousand substances and forms the basis of the recommendations from UNEP-SETAC Life Cycle Initiative regarding characterisation of toxic impacts in life cycle assessment.

TL;DR: The presented method is useful for environmental decision-support in the production of water-intensive products as well as for environmentally responsible value-chain management.

TL;DR: In this paper, the authors reviewed a multitude of methods and indicators for freshwater use potentially applicable in life cycle assessment and identified the key elements to build a scientific consensus for operational characterization methods for LCA.

TL;DR: In this paper, the authors propose a framework to address this methodological limitation and to support further quantitative modeling of the cause-effect chain relationships of water use and provide a description of possible impact pathways for life cycle impact assessment (LCIA), including indicators on midpoint and endpoint levels that reflect different areas of protection (AoP).
