The US is by far the greatest emitter of greenhouse gases compared to other industrialized nations. The US comprises about 4% of the earth's population, but emits about 25% of the total global greenhouse gases.

The chart shows that US carbon dioxide emissions, at over 20 tons per person annually, are over six times that of the global average (ignoring the US).
When compared to 1.3 billion people of China, the 290 million people in the US emit over seven times as much, per person. Viewed in aggregate, the 290 million Americans emit 65% more carbon dioxide annually than the 1.3 billion Chinese do in total. And when compared to the 1.1 billion people of India, the 290 million Americans emit over 20 times as much, per person. Again, looked at in aggregate, the 290 million Americans emit 5.5 times the amount of carbon dioxide that the entire Indian nation of 1.1 billion people does in total.
