# Regulation (EC) No 2327/2003 of the European Parliament and of the Council of 22 December 2003 establishing a transitional points system applicable to heavy goods vehicles travelling through Austria for 2004 within the framework of a sustainable transport policy, Division 1: The following documents must be submitted by the driver of a heavy goods vehicle each time it crosses the Austrian border (in any direction):

Extent: E+W+S+N.I.

(a) a document showing the COP value for NOx emissions from the vehicle in question;
(b) a valid points card issued by the competent authority.
Concerning (a):
in the case of EURO 0, EURO 1, EURO 2, EURO 3-standards heavy goods vehicles registered after 1 October 1990, the document showing the COP value must be a certificate issued by the competent authority giving details of an official COP value for NOx emissions or the type-approval certificate showing the date of approval and value established for type-approval purposes. In the latter case the COP value will be the type-approval value plus 10 %. Once such a value has been determined for a vehicle it cannot be changed during the vehicle's life.
In the case of heavy goods vehicles registered before 1 October 1990 and heavy goods vehicles for which no certificate is submitted, a COP value of 15,8 g/kWh will be set.
Concerning (b):
the points card/ecotag contains a certain number of points and is endorsed as follows on the basis of the COP value for the vehicles in question:
1.. each g/kWh of NOx, calculated according to point (a), counts as one point;
2.. NOx emission values are rounded up to the next full point if the decimal is 0,5 or more, otherwise they are rounded down.
