EU: Heavy-duty vehicles – specifications on reporting and treating additional data 

 

The EU Commission published a new legislative initiative which follows up on the inclusion of new vehicle sub-groups and technologies in the amended Regulation (EU) 2019/1242 which sets CO2 emission standards for heavy-duty vehicles. 

It aims to add certain additional data needed to fully reflect the broadened scope in the monitoring and reporting obligations under the Regulation. 

This Delegated Act revises Annexes IV and V to Regulation (EU) 2019/1242 to ensure that Member States, manufacturers, and other stakeholders report additional data, that sensitive information is safeguarded from public disclosure, and that certain aspects of the reporting process for technical services are clarified. 

The amendments primarily reflect the extension of the Regulation’s scope to additional categories of motor vehicles and trailers under Regulation (EU) 2024/1610, as well as related updates to Commission Regulation (EU) 2017/2400 (as amended by Regulation (EU) 2025/2584) and the forthcoming revision of Implementing Regulation (EU) 2022/1362, which will incorporate new heavy-duty vehicle technologies. 

In particular, some changes are needed to properly establish reference emissions for trailers and buses based on monitoring data from the 2025 reporting period (covering 1 July 2025 to 30 June 2026), in support of the implementation of Regulation (EU) 2019/1242. 

The Act also introduces requirements to report information on manufacturers of certain vehicle components, which is necessary for risk assessment in the verification of in-service CO₂ emissions from heavy-duty vehicles. 

While Regulation (EU) 2024/1610 already allows technical services to report on behalf of manufacturers under certain conditions, this Delegated Act further defines key elements of that reporting process. 

Additionally, it introduces new monitoring parameters only for selected vehicle types, ensuring their proper inclusion while keeping reporting obligations proportionate and streamlined. At the same time, certain data points are excluded from publication to protect sensitive information. 

Finally, the Act includes targeted textual corrections to Regulation (EU) 2019/1242 to improve clarity and facilitate more efficient reporting.
