proving carbon emmisions
kp - 28/8/12 at 09:34 PM

I got my locost registered in Ireland (republic of) back in May, happy days. Except that they have classified the car as category G for purposes of road tax. Which means I'm liable to pay 2100euro per year in road tax!!

The reason for this was because I didn't produce a manufacturers european certificate of conformity, so they put me in the highest tax bracket by default. (it's a 1.6l petrol engine BTW)

What they need is 'proof' of my of my carbon emissions in co2 g/km

Any idea how I could document/prove my carbon emissions?


I did find this formula in some EU documentation;

quote:

Petrol engine and manual gearbox:
CO2 = 0,047 m + 0,561 p + 56,621

Where: CO2 is the combined mass of CO2 emissions in g/km, "m" is the mass of the vehicle in running order in kg and "p" the maximum engine power output in kW.




But the authorities here said that it didn't apply to my car (it only applies to californian imports!).

can an mot station not do it?

couldn't you have them measured by an MOT station or something similar

could you maybe write to the engine manufacturer quoting engine numbers, model, as much info as you can from the original car it was in (if possible) and ask for a letter detailing the official figures from when it was new
ok, maybe older engines wouldn't have really had this info before everyone got all worked up about the greenhouse gasses myth, but i suspect they'll only take the manufacturers word for it?
same way that here we often have to proove engine age, and IVA and DVLA like to see letters from the likes of Ford, or Vauxhall confirming the age etc

Afraid it can't be done... well not cheaply!

"co2 g/km" depends upon the whole car package, not just the engine, so the figures from the car the engine came from have no relevance to yours.

How are classic cars (ie. ones made before the figures were declared for cars) tax bands worked out there in Ireland?

I though that the Carbon emissions figure is a theoretical calculation based on a number of factors s with most carbon figures. Have a look at the Carbon Trust to see if they show you how its worked out.

There are two road tax schemes in ireland. Cars registered pre-2008 cars pay motor tax based on their engine size (cc). All cars registered on or after 2008 are on the co2 emissions scheme.

My car is new (registered 2012) because it has a new chassis (even though the engine & running gear are from a 1989 sierra).

As far as I know, emissions are calculated similar to the old MPG figures, which takes in to account aero resistance, rolling resistance, motorway & city driving etc, etc, Not a simple exhaust measurement. Anyone know how a small manufactures calculate emmissions?

or try the government!!

Link to Direct.gov

ETA: or failing that, get the emissions conformity certificate from the original car that the engine belongs to, then prove that some elements are BETTER, such as weight and acceleration.

MakeEverything,

I've been in constant contact with our department of transport nd department of finance (who oversee car registration). They say that the only evidence they know of is a conformity certificate.

Conformity certificates and co2 emission figures were not required nor were they produced for cars in the 80's (my donor car was 1989)
