Article 10 — Communication and transparency

1. Transport and hub entities and data intermediaries shall disclose output data in a clear and unambiguous manner, whenever possible, prior to the provision of a transport service or the conclusion of a transport contract. When transport and hub entities and data intermediaries disclose output data, in the communication accompanying that disclosure they shall include the statement Greenhouse gas emissions calculated in accordance with Regulation (EU) 2026/1030 in at least one of the official languages of the institutions of the Union, and where possible, also in an official language of the Member State on the territory of which the service is performed. 2. Transport and hub entities and data intermediaries may choose to display visibly the following information: (a) whether their data is subject to the verification referred to in Article 12(1); (b) whether they have exclusively used primary data for their calculations of output data; (c) whether they have used the EU calculation tool referred to in Article 8. 3. Where output data are obtained and disclosed by a data intermediary which does not calculate emissions on the basis of separate arrangements, paragraph 1 of this Article and Article 9(3) shall apply. When disclosing output data, the data intermediary shall include a reference to the source of that output data. 4. Where primary data are used, transport and hub entities and data intermediaries shall be entitled to communicate that fact to any third party, provided that the use of primary data has been ascertained in accordance with the verification provided for in Articles 12 and 13. 5. Transport and hub entities and data intermediaries which calculate greenhouse gas emissions shall be able to provide evidence substantiating how the output data were established. That evidence shall be provided in accordance with the common methodology referred to in Article 3(1), and: (a) it shall serve as a basis for the verification carried out in accordance with Articles 12 and 13; (b) it shall be made available upon request of a competent authority designated under Union or national law, or another third party in so far as separate legal or contractual obligations apply; (c) where the verification is carried out in accordance with Articles 12 and 13, it shall include a reference to the proof of compliance referred to in Article 13(6), and the contact information of the conformity assessment body that drew up the proof of compliance; (d) where the output data are established through the use of an external calculation tool referred to in Article 9(2), it shall include a reference to that calculation tool. 6. The output data and the evidence referred to in paragraph 5 shall be established in a clear and unambiguous manner, in at least one of the official languages of the institutions of the Union. Where possible, they shall be made available in the form of a weblink, QR code or equivalent. 7. Personal data shall be processed in accordance with Regulation (EU) 2016/679 of the European Parliament and of the Council. 8. Any recipient of output data and of the evidence referred to in paragraph 5 shall take measures to ensure the confidentiality of relevant commercial data that are processed and communicated in accordance with this Regulation, and to ensure that such output data and evidence may be accessed, processed and disclosed only when authorised.
