 [Monitoring of CO2 emissions from passenger cars – Regulation (EC) No 443/2009]
Hello,
I have a question concerning the provisional 2018 CO2 data of passenger cars which I downloaded from here:
https://www.eea.europa.eu/[…]/co2-emissions-cars-2018-provisional

As a total average CO2 value I get 120.6 g CO2/km NEDC when I discard the cells without CO2 value (Enedc (g/km)). In the press release it says the average CO2 value is 120.4 g CO2/km:
https://www.eea.europa.eu/[…]/average-co2-emissions-from-new

Including the empty CO2 cells - which are then counted as Zeroes - I get an average of 117.5 g/km.

Is there an explanation why there is a difference? By the way the total new registrations in the file (including Iceland) amount to 15,273,273 units. Without the empty CO2 fields the total is only 14,876,238.

When I look at the petrol registrations, they amount to (excl. empty CO2 fields) 8,847,862 units and the average CO2 value is 123.6 g CO2/km, in the press release it is only 123.4 g CO2/km.

The Diesel average CO2 is 121.5 g CO2/km in the press release and in my calculation using the file.

Do you have any explanation for this?

Thank you.

Dear M. 'Alexib',

Thank you for contacting the European Environment Agency (EEA).

Having verified our calculations, we can confirm the numbers included in the press release. Please note that missing Enedc values should not be considered as zeros. Zero values are only valid for electric vehicles. Furthermore, there are vehicles that are considered as out of scope when it comes to the calculation of the average CO2 emissions, e.g. duplicates, national small series, individually approved vehicles are excluded from the calculation of average CO2 emissions.

We hope that this information may be useful for you.

With kind regards,
EEA Enquiry Service
