If you believe the media right now it's China just for the shear number of people doing wrong and the lack of green initutives but they are getting better. The US is a great polluter..mostly I think it's the attitude of bigger and better. Every one seems to need a bigger faster car and huge houses. I live in the US and one of the questions I most often ask people is that if the speed limit on the interstate in most places is 60-70 miles an hour why do you need a car that goes 145 MPH ?or even 90 MPH ? I guess I would have to say the US with China a very close second but that is personal opinion and not a statement of fact.
From what I understand, I think that the United States is probably the biggest polluter. For such an advanced nations, we sure are stupid about some things.
