G7 countries have the clout to make life difficult for any nation that isn't a member, and they have the clout to help any nation that isn't a member as well... in this case, they were offering the latter - even if only as lip service - as the discourse taking hold throughout their own countries and the world is that a vital part of our eco-system is being allowed to burn, and quite possibly for corporate profit. It is what it is. I think you'd be naive to think that the worlds leaders wouldn't take an interest or if - as you've implied - you think they should just butt out and not take an interest at all. If their people worry about it, they will.
