LCA methodology description

Introduction My previous post identified how a process specification perspective can be applied to provide some structure and semantics for methodology description and execution, taking the Life Cycle Assessment (LCA) methodology as example. In this article, we'll apply this perspective and expose a well-rounded ontology that captures the full Life Cycle Assessment (LCA) methodology description. To keep the core structure of the ontology within context, we'll reuse the four basic notions provided by the Process Specification Language (PSL) ontology (ISO18629-1:2004). These ... Read more

A process specification perspective on LCA

Introduction Life Cycle Assessment (LCA) is a methodology for studying a product system, from a sustainable engineering viewpoint, and quantifying and evaluating the environmental burden of that product system during its entire lifecycle. By objectively understanding the environmental profile of a product system, it becomes possible to propose and evaluate alternative product systems with potentially lesser environmental impact, where the results of the study are used to drive decision making. LCA considerations are highly important and should be factored into any ... Read more
