The first thing I would do is go over the investor-state dispute settlement chapter and make it crystal clear that you're not reducing the regulatory space of states to take action on climate change and other things. The other thing I would do is get a good environmental lawyer, of which there are many in this country, and have them redraft the text to make the text go from this nice language of motherhood and apple pie to actual stuff that has legal content. I'm sure that as people who draft the laws that we now are under, you understand the difference between “should” and “shall”, for instance.
I'm sorry that I can't give you a whole range of specific actions. That's not really my expertise in terms of legal drafting.
