Here's what I think is going on. So let's say you're an influential shareholder at a big company, this company has been successful because it did a few things well, and there are a bunch of other shareholders with their own agendas. Meanwhile you are a human being just like any other so fundamentally you're making decisions about what you're going to do with your own life, which is the only thing you really control. Now, you're concerned about climate change. Does it really make sense to try to lasso this big company into doing something about climate change, if it has no experience in that field, and no one there joined in order to work on climate change? More likely you would put some of your own (presumably considerable) resources into some other project that's focused on climate change. Because that's going to have a better chance of success than trying to sequester resources away from BigCorp for something that BigCorp fundamentally isn't committed to. The point is you are an investor and it just doesn't make sense to invest resources into X with the goal of doing Y's job. You would invest in Y instead. Put another way if you own an all-star basketball team and you want to win an ice hockey championship you don't tell them to start playing hockey on the weekends, you use the money they made to go buy a hockey team.
