US emissions standards versus EU
Since the topic came up in another thread and I did not get a chance to explain myself before it was closed. As you can see in the links below, US emissions standards are more lenient towards GHG v...

Shinerbock, I don't know what other thread you are talking about, or what point you exactly are trying to make?
According to those links, US engines pollute less, are required to be tested for compliance more often, and have better and longer lasting emission control equipment on them.
From the ICCT link:
"Compliance and enforcement is the most critical aspect of all regulations and the key to success of US and CA policies. US/CA programs are both more complex and more rigorous while providing more flexibilities to manufacturers."
That is actually what I've read/heard over the years regarding US vehicles.
Hopefully Europe will catch up to the USA regarding pollution controls?
A certain member from Australia, who absolutely hates the US and North America in general, kept saying that the EU has stricter diesel emissions regulations and the thread(which was about an EU diesel) was closed before I can prove it so I decided to start a new thread specifically about US versus EU emissions to clarify.
The EU is actually stricter than the US regarding gasoline vehicles emissions from new vehicles, but are far more lenient that the US with diesel emissions. This is a major reason why we see more gasoline vehicles in the US versus diesel, and more diesel vehicles in the EU versus gas/petrol. However, as you pointed out, once these vehicles are sold, regulation is hardly enforced depending on the country and the EU emissions systems are not required to last as long as they are in the US.
Also, there have been some here that seem to believe that emissions from diesel pollute have more effect on the the atmosphere than gasoline emissions which is false. Gas engines emit more gasses that effect the atmosphere while diesels emit gases and PM that is more hazardous to human health over time. These gases are mainly hazardous in highly populated areas(especially in hot climates) and will dissipate into the atmosphere where they become good for the atmosphere(since it is an ozone gas) in less populated areas. Although, ironically, gas emissions will kill you quicker than diesel emissions would in a closed space since they emit more CO2.
