Description of the issue

The project "Conversions" was created. Please add respective issues to it.

Ideas of solution

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
• I added this issue to the Project 'Issues'. If suitable, I add it to further Projects.
• The goal of this ontology is clear to me

I am aware that

• every new entry in the ontology should have an annotation
• classes should arise from concepts rather than from words

Two of the terms are covered by #420.

We discussed today that concepts from the conversion papers are the core of the 1.2 release.

Which terms do we need to cover? A list of concepts to be covered would be nice.

So far in issues we discuss(ed) the following concepts:

• CO2 equivalents (Include "CO2 equivalents" and "global warming potential" #420, currently open)
• global warming potential (Include "CO2 equivalents" and "global warming potential" #420, currently open)
• gross domestic product (Add gross domestic product #454, already implemented)

What else do we need?

The concepts CO2 equivalent, global warming potential and gross domestic product are covered by the OEO. Do we need further concepts from the briefings? Else we could/should close this issue.
