Type-approval authorities shall, without delay, report to the Secretary of State any deviations in the CO2 emission values of heavy-duty vehicles in service as compared to the values that are indicated in certificates of conformity or in the customer information file referred to in Article 9(4) of Regulation (EU) 2017/2400 , as it has effect in domestic law, and as that Regulation has effect in EU law as amended from time to time and by virtue of the Northern Ireland Protocol, as a result of verifications performed in accordance with the procedure referred to in Article 13 of this Regulation.\n2. The Secretary of State must take into account the deviations referred to in paragraph 1 and any other deviations from information provided by the manufacturer for the purpose of calculating the average specific CO2 emissions of a manufacturer and the reference CO2 emissions, but is not required to take into account such deviations if a recalculation of a manufacturer’s average specific CO2 emissions or the reference CO2 emissions results in a deviation of less than 0.1% from the original calculation. The Secretary of State must, where appropriate, amend the list referred to in Article 11(1).\n3. The Secretary of State may by regulations adopt detailed rules on the procedures for reporting such deviations and for taking them into account in the calculation of the average specific CO2 emissions. ...",
