Measurement of CO2 emissions

[Rowland2094]

The CO2 emssions of a car are measured whilst the car is on a rolling road and carrying out a driving cycle that simulates various driving conditions. What is this cycle? Are there any figures as for mpg, for example CO2 at 70 on motorway, at 60 at et., etc., It seems that the present figures don't really tell a true story and the CO2 figures, tax allowances and scrappage schemes are designed to revive an industry rather than reduce co2 production. For example I have a peugeot 205 1.8 diesel. It does 70mpg if driven at 60mph - does it pollute less than a fast large saloon doing only 25-30mpg at 70 on the motorway. How can I find the co2 figures for my car? Bashing Google has produced few results does anyone know the facts?

Hi, unless its the car makers rolling road, run of the mill one will not give out proper figures, age of car, miles it has done, type of fuel used, type of service that car / van has had, type of driving conditions, rain, wind, snow,ice, speed bumps, tyres,+wheels ( Alloy Metal) & many other conditions, Example in my own case, if the road is rough I take my time. I hope this enlightens you a bit more.

Thanks for taking the time to answer me. I am not really sure you understood the question - I am looking for sources of information that may give me definitive answers on the cycle and existence of fuel consumption/co2 production figures.
