• Well, I got my Certificate of Conformity from Porsche to try to register my old 911 for the ULEZ.

    Got it in the post this morning - apparently the 'Abgasverhalten' for Nox + HC is 0.187g/km, and Nox alone is 0.035g/km. I'm not actually sure which the ULEZ measures, but the figure to beat for a petrol car is, I believe, 0.25g/km. So either way it should be compliant.

    On to the TFL side of the operation, which I suspect will be less simple...
