Well, I think capitalism can be summed up as "optimize for one metric: capital". In a capitalist world, if you want to change what companies are doing, make it more expensive to do so (alternatively, less lucrative). So I guess tax and fine companies, like GDPR does. I wish there was a simple way to add more metrics like pollution, social impact, health impact, etc. But those are rather hard to measure, usually not immediately available, and can be hidden in some way or another. It might be doable, though, as we were more or less able to do so with capital (track monetary exchanges, etc); which is a completely artificial metric. Disclaimer: I know nothing about actual economy theories.
