DieselNet: Diesel Exhaust Emission Standards

1997 would have been the end of Tier 1. The standards for diesel passenger cars was NOx of 1.25 g/mi and PM of 0.1 g/mi on the FTP 75 test.

Heavy duty trucks are engine-certified (not vehicle-certified) on the FTP test. Current standards are 0.2 g/hp-hr for NOx and 0.01 g/hp-hr for PM. If you assume a typical cruise condition for a semi truck of 250 hp and 65 miles per hour that works out to be NOx of 0.77 g/mi and PM of 0.04 g/mi.

So your 15 year old passenger car puts out roughly double the emissions of a 2012 semi truck.
Your truck has roughly the aspect ratio of a billboard.

I remember driving into the LA basin in the 1960's. It was cars, bubba, that made it as nasty as it was.

People attending the Olympics in China often had to wear masks because the "air" was so "thick" at times...we just exported the "smog" along with the "jobs" to China.

Except they shut down industries and power plants ahead of the Olympics to let the polution clear out. So what was seen was polution mostly from cars.

I also saw other cities air clean up over the years even though they doubled in size during that time without any major manufacturing polution.

Green diesel is made from 100% organic matter!
Just like coffee only stronger.
We pay more for our diesel then gasoline because its fair trade diesel, to help increase the living standard of the country it was produced. Arabs for instance cannot afford grass or lakes and outdoor pools without our help.

...with all due reverence to the original French battle cry "...let them eat CAKE!" I think it should be changed to "...let them eat OIL!"
