Some countries are doing more than others, which is why Kyoto was such a bust. The signatory countries have all but admitted that there is no way they can meet the protocol.The biggest reasons Kyoto was a failure out of the starting block is that they set limits to low for any country to reasonably reach, there was no enforcement mechanism, and the countries that are the biggest polluters (China and India) were not required to abide by the restrictions whether they were signatories on the treaty or not.

Yes, the US uses more energy per capita than most other countries, but we also produce energy in cleaner ways than most countries, the sole exception being the old (not all, just the truly ancient) coal fired plants that were grandfathered under the clean air act. The US doesn't send brown clouds across the ocean to other countries (China and India both do), it's damned near illegal to burn lignite in the US (China's main source of coal is lignite) and chemical dumping is completely illegal in the US. Most of the current chemical pollution in the US is due to accidental spills or residue from chemical spills and dumping in earlier times when the results were not known and not monitored.
