The U.S. is still the worst as far as being responsible for the most pollution and contribution to climate change. Companies outsourced all the manufacturing to China and other countries, so there are fewer regulations and controls. Then there is the fuel expended for shipping the goods to the U.S. along with the U.S. Navy patrols that protect these shipments (per a Navy commercial a few years ago).
