Modern technology has made modern diesel as clean or even cleaner burning than gas in many angines. This is especially true for any gas engine that is burning gas with ethanol.

The laws of physics have not been repealed. When ethanol is added to gasoline, as is required in some states, the result is that more gasoline is burned in that engine per mile driven along with the ethanol burned. Burning more gasoline results in more emissions per mile no matter how much ethanol is burned along with the gas. Burning the ethanol also results in more emissions from the ethanol also. Ethanol produces less energy per volume than gasoline so when added to gasoline more total volume of the mixture of gas and ethanol is required to produce measured energy.

Modern diesel engines have been improved to be cleaner fuel burning that even most gas cars today. Our newer diesel tractors and trucks now require the addition of DEF to the exhaust system. After the DEF law was passed, Cummins engines were able to have an exemption for a few years since DEF actually has no effect on the combustion of diesel fuel in an engine. Adding DEF to the exhaust system of any diesel engine actually has no reduction of any exhaust of burning diesel. DEF added to the exhaust of a diesel engine does increase pollution, adding Nitrous Oxide to the atmosphere that we breath.

I want some of what you've been smoking. :)
