If you ask, let's say, a football player: "How many goals did you score last season?" the guy would know the number. If you ask me as an investor, you know, what was being your performance last year, I would know that number, and if anyone mentioned sustainability in asking, "What's your CO2 footprint of your institution? Scope 1, 2 and 3, last year, accumulated and break me down and most importantly, which assumption did you use in order to calculate the number?" If he can't explain the workings, the math, then you know he's a liar. It's as simple as that.
