I know what AdBlue does, but that is just another chemical burning, so other harmful gasses get out of your exhaust, they don't want to know about right now.
And as I use less diesel when travelling than the old NEDC, I will also have less CO2 and other gasses than one who consumes more diesel.
Good luck finding yourself a "California" where you have the same, or let's say more freedom to travel like you do now with "bad" non-bio fuel.
Don't forget that that bio in your B7 isn't that bio, considering the demolishing of precious nature for growing infertilizating plants for your bio.
Bio isn't that bio.
And as Belgium is planning to ban second hand ICE vehicles in the very near future, I will keep on burning fossilized plants and organisms from the past, that contains a lot of CO2 and other gasses from long time ago. In fact, burning fossile fuel is more CO2 neutral than burning plants that didn't take up that much CO2 before they were being cropped. And this in the first EURO 5 engine from the T5.1 (october 2009, long before it was obligatory to have EURO 5 engines in commercial vehicles, and no, I don't have cheat software in my California!).
And that is all I want to add in this conversation, because this is going nowhere.
