There was a couple of The Guardian investigations, but it was mostly about another type of questionable carbon credit source, forest protection: https://en.wikipedia.org/wiki/Verified_Carbon_Standard#Controversies https://en.wikipedia.org/wiki/Verified_Carbon_Standard#Contr... And the fact that this article mentions Gold Standard as being much better with the cookstoves and it avoiding some of that forest credits makes me think it's the good carbon credit issuer. Anyone with access to the scientific article proper can tell who issued the carbon credits for cookstoves? edit: I also forgot where I read this but IIRC Verra has more corporate origins while Gold Standard comes from the NGO world may also be relevant.
