Alas the USA collapsed the deal then and it is on its way to trying to collapse the Paris agreement now. The oil companies are fully aware of this and have been as long as we the people have been since the science was settle 5 decades ago. They can't be sued for our collective choice to not do anything, that isn't fair.
It will increase the potential costs they consider the next time a major industry has to choose between ending human civilization and their quarterly profits.
It will punish shareholders who supported this behaviour.
It's not the only answer but I don't see any way that it hurts.

So the lawyer is saying that if a company spends tens of millions on advertising, that it has no effect on the economy that he is arguing is causing global warming?
The only purpose of the advert is to make people buy from Chevron instead of their competitors, but the same amount of oil is getting sold either way.
