  "heading": "Certification of CO2 savings",
  "text": "1. The Secretary of State shall ensure that CO2 savings achieved from the use of the innovative technology have been determined using the methodology set out in the Annex.\n2. Where a manufacturer applies for the certification of the CO2 savings from the use of the innovative technology in more than one 12 volt motor-generator in relation to one vehicle version, the Secretary of State shall determine which of the 12 volt motor-generators tested delivers the lowest CO2 savings. That value shall be used for the purpose of paragraph 4.\n3. Where the innovative technology is fitted in a bi-fuel or flex-fuel vehicle, the Secretary of State shall record the CO2 savings as follows:\n(a) for bi-fuel vehicles using petrol and gaseous fuels, the CO2 savings value with regard to LPG or CNG fuels;\n(b) for flex-fuel vehicles using petrol and E85, the CO2 savings value with regard to petrol.\n4. The Secretary of State shall record the certified CO2 savings determined in accordance with paragraph 1 and 2, and the eco-innovation code referred to in Article 5(1) in the relevant type-approval documentation.\n5. The Secretary of State shall record all the elements considered for the certification in a test report and keep that together with the verification report referred to in Article 3(2) ....\n6. The Secretary of State shall only certify CO2 savings, if the Secretary of State finds that the innovative technology complies with the conditions set out in Article 1, and if the CO2 savings achieved are 1 g CO2/km or higher, as specified in Article 9(1)(a) of Implementing Regulation (EU) No 725/2011 in the case of passenger cars, or as specified in Article 9(1)(a) of Implementing Regulation (EU) No 427/2014 in the case of light commercial vehicles.",
