Add life cycle assessment

[stap-m]

Description of the issue

For the study factsheet descriptors we need to add the term Life cycle analysis.
Use case: Describing a scenario study that contains a life cycle analysis.

Ideas of solution

Make it subclass of study¹.
Make LCA alternative lable.

Workflow checklist

• I discussed the issue with someone else than me before working on a solution
• I already read the latest version of the workflow for this repository
• The goal of this ontology is clear to me

I am aware that

• every entry in the ontology should have a definition
• classes should arise from concepts rather than from words

Footnotes

1. A study is a project with the goal to investigate something. ↩

[l-emele]

The more common term is life cycle assessment, see e.g. Google NGram Viewer.

Existing definitions/descriptions:

• Wikipedia: "Life cycle assessment or LCA (also known as life cycle analysis) is a methodology for assessing environmental impacts associated with all the stages of the life cycle of a commercial product, process, or service."
• EnArgus: "Die Ökobilanz ist eine Methode zur Abschätzung von Umweltwirkungen bei der Herstellung von Produkten oder der Durchführung von Prozessen und Dienstleistungen."

So I prose:

• life cycle assessment: A life cycle assessment is a methodology that assesses environmental impacts of the life cycle of a material entity or process.
• Alternative labels: life cycle analysis, LCA, Ökobilanz (de), Lebenszyklusanalyse (de)

[u-mueller]

I agree to your proposal.

[stap-m]

• life cycle assessment: A life cycle assessment is a methodology that assesses environmental impacts of the life cycle of a material entity or process.

In the sense of using other words than in the lable a slight adjustment: ... a methodology to calculate and analyse environmental impacts of the life cycle of a material entity or process. ?

@u-mueller do you want to implement?
