To learn about sustainability control there are a number of blog posts here but also articles in the media and academic articles and book chapters that I have written.
Generally about sustainability control
Debate article in Norwegian daily Bergens Tidende, proposing two indicators of sustainability in the fashion industry and arguing that, using these indicators, the fashion chains are very far from sustainable: http://www.bt.no/btmeninger/debatt/Slutt-a-handle-hos-storkjedene-335211b.html
I was interviewed about how to identify a sustainable investment in no 2-2020 of Norwegian magazine Dine Penger.
But have also published in academic journals and books about the subject:
