That holds true when you need proxies for the thing you really care about. You can't just tell VPs, departments, etc to just make more money, which of course is

That holds true when you need proxies for the thing you really care about. You can't just tell VPs, departments, etc to just make more money, which of course is what most KPIs are going to seek to do in one way or another. So we construct measurements that should reasonably result in increased profits for the company. And these then become gamed whereby the measurement goes up, but the profits do not. Carbon is actually interesting because we don't actually need proxies. Put a global cap on emissions and enforce it like the existential threat it is, and then let the market trade around it. Auction off the allowances to fund/subsidize other things.
