Pursuant to Articles 18 and 26 of Directive 2007/46/EC of the European Parliament and of the Council of 5 September 2007 establishing a framework for the approval of motor vehicles and their trailers, and of systems, components and separate technical units intended for such vehicles2, a manufacturer must ensure that each new light commercial vehicle placed on the market in the Union is accompanied by a valid certificate of conformity and a Member State may not register such a vehicle unless it is accompanied by such a certificate. In accordance with Annex II to Regulation (EU) No 510/2011, data collected by a Member State to monitor the manufacturer’s compliance with Articles 4 and 11 of that Regulation are to be consistent with a certificate of conformity and based on this document only.

Regulation (EC) No 443/2009 of the European Parliament and of the Council of 23 April 2009 setting emission performance standards for new passenger cars as part of the Community’s integrated approach to reduce CO₂ emissions from light-duty vehicles3 requires the Member States to use the certificate of conformity as a data source but allows for the use of other documents providing equivalent accuracy for the monitoring and reporting of CO₂ emissions from passenger cars. In order to ensure cost-efficient and accurate monitoring and reporting of CO₂ emissions data for light commercial vehicles, it is appropriate in the short-term to allow Member States to use the same procedure and data sources for the monitoring and reporting under Regulation (EU) No 510/2011 as those used for reporting under Regulation (EC) No 443/2009. Therefore, Annex II to Regulation (EU) No 510/2011 should, where duly justified, allow for the use of other data sources providing equivalent accuracy for CO₂ monitoring and reporting purposes. The Member States should put the necessary measures in place to ensure adequate accuracy in the monitoring procedure.
