The imbecile in the first link I posted, Alexandria Ocasio-Cortez is a congresswoman that has absolutely zero credibility about anything she talks about and yet she is the new darling of the Democratic party. Really a horrific thing that the lunatic left supports her.
When asked why she thought President Trump should be impeached, she said that there are just to many reasons to list but could not give even one example.
I think VOC's (Volatile Organic Compounds) are completely miss represented in the scheme of things. When VOC's are quoted for gasoline, the VOC's for refining, transporting and storage are completely ignored. If you look at the complete picture for VOC's, Diesel total emissions for VOC's are substantially less than for gasoline.
A little nugget that completely relates to VOC evaporation: The flash point is a descriptive characteristic that is used to distinguish between flammable fuels, such as petrol (gasoline in the US), and combustible fuels, such as diesel.
Diesel vehicles don't even need an evaporative system like gasoline cars do because Diesel's evaporation rate is close to non existent at normal temps a vehicle would encounter. Yup. Completely ignored by the EPA.
