    Default Are my CO2 emissions correct? MOT Test

    I was just looking over my MOT test results, and noticed the CO2 emissions from the 'MOT Exhaust Emissions Test Results'.


    FAST IDLE
    Engine speed: 2500-3000rpm manual check - PASS
    CO: max 0.200% actual - 0.096 - PASS
    HC: max 200ppm actual - 47 - PASS
    Lambda: 0.970-1030 actual - 0.998 - PASS

    NATURAL IDLE
    Engine speed: 450-1500rpm manual check - PASS
    CO: max 0.300% actual - 0.108% - PASS

    OVERALL RESULT
    Exhaust Emissions Test - PASSED






    I am looking at the CO result, and seeing the 0.096 and 0.108.
    Are these the CO2 emissions which are mentioned in a Car's specs?

    I thought the new Fiesta has low emissions at 98..

    From that I asume that these have nothing to do with CO2 emissions?
    I'm just wondering if I'm paying the correct Road Tax based on CO2 emissions, as it's a bit annoying when I pay £265/year when my friend pays about £25/year...

    CO = Carbon Monoxide
    CO2 = Carbon Dioxide

    Two different beasts.

    As nick_s said, CO and CO2 are different -

    CO is determined by condition of various elements within the engine and exhaust.

    CO2 is a figure calculated by the vehicle manufacturer and declared to DVLA to determine taxation band in the UK.

    Funny thing is, carbon monoxide is more likely to kill you than carbon dioxide.....and we get taxed on the less lethal of the gasses. Go figure

    Pigs me off a fair bit when they go on about cars with big engines polluting more .... I remember one particular MoT on my old K plate 3.0 24v Senator.....
    HC - Max 1200ppm ... Actual 0006ppm

    Sod getting some dinky little toy car with a lawnmower engine that's running at 100% at all times.... I'll stick with my 3.2 that's running at 50-70% most of the time... (and about 95% when I feel like a little fun ).


    Rant over.
