> Take climate change. If every corporation took a carbon negative stance like Stripe and Microsoft, that would make a big dent in carbon emissions.

But then some corporation would move away from that, get extra money and eat competition who is more green/moral/etc.

Competitive economy maximizes profits in the space allowed by regulations. That's a feature, not a bug. But it also means that expecting some sectors/inputs to become unfashionable and die out is very close to wishful thinking.
