A properly designed system for verifying the compliance of greenhouse gas emissions output data disclosed on the market and underlying calculation processes with the requirements laid down in this Regulation, should substantially increase trust in the reliability and accuracy of those data. Specifically, it should lay down detailed conditions governing the verification, irrespective of whether a one-off or regular service is concerned, including the appropriate frequency of checks, and procedural arrangements, taking due account of the nature and scale of the transport services concerned and the necessity of avoiding disproportionate administrative burdens. Transport and hub entities and data intermediaries that have successfully undergone the conformity assessment should be entitled to obtain a proof of compliance, to be commonly recognised across the Union. Where primary data were included, the proof of compliance should acknowledge its inclusion, especially to incentivise the collection and use of primary data by any entity concerned by this Regulation. The verification of output data should include the comparability of such output data, including in relation to the calculation of distance, where deviations from the great circle distance and shortest feasible distance should be checked for their consistency with the EN ISO standard.
