The per capita argument is a strawman. Yes, we 300 million Americans produce more pollution per capita than the 1.2 billion Chinese. We also produce more pollution per capita than the Indian population. When you look at the big picture, however, you realize that China DOES produce more pollution than the US. The pollution that China is producing is on the rise, while the US is declining in pollution and has been for decades. It is ALSO true that the US is producing more CO2 now, but that is not pollution. It IS a greenhouse gas, but not pollution. The fact of the matter is that the U.N. wants the U.S. to pay money to other countries AND to reduce our use of energy. If we work less, produce less, etc. we will have less money to work on environmental progress, since the clean answers are a lot more expensive than the old, dirty way of working. If it were JUST a commitment to reduce our greenhouse gases and particulate pollution, I'd be all for it. It isn't. It's about the U.S. having hard to reach targets with financial penalties, while paying others, who have no commitments at all, money to compensate them for our having "polluted" the world with out presence.
