No, if anything the US is lagging behind most other developed countries in this area, and as the US is the largest producer of carbon emissions of any country (by a long way), its lack of action and bad example is upsetting the rest of the world.
Cars. Back in 1976 it was mandated that all US cars have catalytic converters to transform the carbon monoxide (CO) to carbon dioxide (CO2). Was that a good thing or bad?..you decide
It depends on which country you are talking about. In Australia the carbon tax will only be paid by large emitters of carbon dioxide. This will encourage them to reduce their emissions. Compensation will be paid to most people to cover any rises in prices arising from the carbon tax.
Carbon Monoxide is the most common gas emitted from a car.
passing laws requiring reduction in emissions
The country that produces the most carbon dioxide emissions is China, which is responsible for over 20 percent of carbon dioxide pollution. The overall most polluted city in the world is Ahvaz, located in the country of Iran. Lastly, the country considered the most polluted is Mongolia, which is heavily polluted due to a complete lack of modern energy efficiency and an abundance of outdated technology.
Some examples of pollutants include carbon monoxide (carbon emissions into the air) and lead emissions into water sources. Most of the lead and metallic substances that end up in the river streams are from industrial processes.
Carbon dioxide is a gas most present in the greenhouse gases. If carbon dioxide emissions aren't reduced, they will continue to live on in the atmosphere destroying the ozone layer and resulting in detrimental climate changes.
Carbon emissions
This is a complex question. If we are talking about countries the per capita emissions of the top twenty countries the answer is Australia according to the Union of Concerned Scientists (as of 2008). If we are talking about total per capita emissions of any country regardless of the size or total output, the answer is Qatar. See links below.
