Environmental Policy and Economics

I think this guy had some good ideas. Alot of them were reflected in the text. I dont disagree with his ideas but I wonder who would oversee these types of policies. Including the cost of pollution in the production sounds really good but what if the companies production and output of pollution changes from one month to the next? How do you regulate something like that? How do you keep that cost from being passed on to the consumer? Creating property rights sounds like a good idea because it gives someone responsibility but wouldnt it also give the person or entity who owns it the right to do what if pleased with the property? It seems we always run into trouble when we start to put a dollar value on things that should be priceless. It is interesting that there are painting and artifacts that are deemed priceless but we managed to come up with a dollar value for the very air we breathe!
