Dear Mariëtte,Thank you for a good question and proposal. We have relied on Rawls theories so far but UNGP is definitely an excellent source. Will look at it. Yours Eero
Certainly UNGP framework is certainly an excellent source. However the other theoretical concepts used for different projects also need to be integrated.
In this context I would like to bring out the clarification of UNGP as United Nations Guiding Principles of Business and Human Rights.
Interestingly there is another concept and framework also called UNGP: Un Guiding Principles of Reporting Framework. I would submit to researchers to integrate this princilpe too.
