So I ordered CRIR' Air for the van, Euro 6 petrols from 2017 get the purple 1 pass allowing them everywhere. Same class as hybrid, electric, lpg..... I'm pleased but it's still puzzling that it comes into that category, guess it's low particulates not low co2.
I offset the co2 from growing summer fruit and salad so my conscience is clear..
