Article 8 — EU calculation tool

1. By 2 June 2030, the Commission shall adopt implementing acts, to ensure that a user-friendly, free of charge, simplified EU calculation tool facilitating calculations based on primary data and enabling the use of default values for greenhouse gas emission intensities, where available and relevant, and of default values for greenhouse gas emission factors, in accordance with Article 4(3), points (a) and (b), respectively, is made publicly accessible to transport operators and is designed to support particularly micro, small and medium-sized transport operators. That EU calculation tool shall be updated periodically. Those implementing acts shall be adopted in accordance with the examination procedure referred to in Article 18(2). 2. Where transport operators use the EU calculation tool for the establishment of output data, the verification referred to in Article 12(1) shall not be required to address the correctness of the calculation performed as referred to in Article 13(2), point (c). 3. To foster the widespread application of the EN ISO standard by transport operators, and in particular by SMEs, the EU calculation tool shall be accompanied by a manual, helping SMEs with the implementation of this Regulation and clearly explaining how to use the functionalities of the EU calculation tool. That manual shall be available in all official languages of the institutions of the Union.
