Recital (16)

Attention should be paid not to deviate from the methodological choices of the EN ISO standard, in order to avoid inconsistencies in the calculation of greenhouse gas emissions from transport services on the market, especially in the context of international transport chains. However, it is appropriate for the Commission to assess the need for a possible adjustment of the EN ISO standard from the perspective of Union policies, including upcoming legislation. If the Commission’s assessment concludes that an amendment to the standard or a component thereof creates a manifest risk of incompatibility with the objectives of this Regulation or other applicable Union law, in particular with Regulation (EU) 2021/1119, the Commission should adopt the necessary delegated acts, to prohibit the application of that amendment. If that assessment shows a risk that an amendment to the standard or a component thereof could create undue imbalances in calculating greenhouse gas emissions from transport services in specific market segments or lead to discrepancies between that standard and the objectives of this Regulation or those of other applicable Union law, the Commission should be able to adopt the necessary implementing acts, to request the European Committee for Standardization to revise the standard accordingly.
