TL;DR: The LCA framework and procedure is introduced, how to define and model a product's life cycle is outlined, and an overview of available methods and tools for tabulating and compiling associated emissions and resource consumption data in a life cycle inventory (LCI) is provided.

TL;DR: LCA is evolving into LCSA, which is a transdisciplinary integration framework of models rather than a model in itself, which works with a plethora of disciplinary models and guides selecting the proper ones, given a specific sustainability question.

TL;DR: This article highlights how practitioners and researchers from many domains have come together to provide indicators for the different impacts attributable to products in the life cycle impact assessment (LCIA) phase of life cycle assessment ( LCA).

TL;DR: In this paper, three methods for defining the contents of the analysed system in this respect are described: process tree, technological whole system and socio-economic whole system, and examples are described in the application's multi-output processes and cascade recycling, and the authors concluded that system boundaries must be relevant in relation to the purpose of an LCA, that processes outside the process tree in many cases have more influence on the result than details within the process trees, and that different methods need to be further compared in practice and evaluated with respect to both relevance, feasibility and uncertainty.

TL;DR: In this paper, the International Reference Life Cycle Data System (ILCD) Handbook is criticised for its guidance to the choice between attributional and consequential modeling and for the choice of average and marginal data as input to the LCI analysis.
