The information provided in the application demonstrates that the conditions and the criteria referred to in Article 12 of Regulation (EC) No 443/2009 and in Articles 2 and 4 of Implementing Regulation (EU) No 725/2011 have been met. Moreover, the application is supported by a verification report established by an independent and certified body in accordance with Article 7 of that Regulation. As a consequence, the efficient generator function of the 12 V i-StARS belt-driven starter-alternator proposed by the applicant should be approved as an eco-innovation.

It is therefore appropriate to generally acknowledge and, in accordance with Article 12(4) of Regulation (EC) No 443/2009, attest the capacity of this innovative technology to reduce CO₂ emissions and provide a generic testing methodology for the certification of the CO₂ savings from the use of the generator function of efficient 12 V motor-generators.

The manufacturer should, in order to have the CO₂ savings from efficient 12 V motor-generators certified, provide a verification report from an independent and certified body confirming the compliance of the motor-generator with the conditions specified in this Decision together with the application for certification to the type approval authority.

If the type approval authority finds that the motor-generator presented by the manufacturer does not satisfy the conditions for certification as specified in this Decision, the application for certification of the savings should be rejected.

It is appropriate to determine the reduction in CO₂ emissions from efficient 12 V motor-generators using the testing methodology set out in the Annex.

In order to determine the CO₂ savings it is necessary to define the baseline technology against which the efficiency of the efficient 12 V motor-generator should be compared as provided for in Articles 5 and 8 of Implementing Regulation (EU) No 725/2011. On the basis of the experience gained, it is appropriate to consider a 12 V alternator with 67 % efficiency as the baseline technology.

In order to facilitate a wider deployment of efficient 12 V motor-generators in new vehicles, a manufacturer should also have the possibility to apply for the certification of the CO₂ savings from several different 12 V motor-generators by a single certification application. It is however appropriate to ensure that where this possibility is used a mechanism is applied that incentivises the deployment of only those 12 V motor-generators that offer the highest efficiency.
