Risk Assessment ISV 2025 according to Commission Implementing Regulation (EU) 2025/35
Article 13 of Regulation (EU) 2019/1242 requires Granting Approval Authorities (GAA) to verify, based on appropriate and representative vehicle samples, that the CO2 emission and fuel consumption values recorded in the customer information files of heavy vehicles match those actually occurring inservice. Commission Delegated Regulation (EU) 2024/1127 sets out the guiding principles and criteria for defining the procedures for these verifications, while Commission Implementing Regulation (EU) 2025/35 determines the verification procedures. In-Service Verification (ISV) testing includes several types of tests: the Verification Testing Procedure (VTP) tests, air drag tests, tyre Rolling Resistance Coefficient (RRC) tests, mass tests, and dedicated tests to verify the presence of Artificial Strategies (AS).
Article 3 of (EU) 2025/35 requires the Commission to set out a risk assessment methodology and each year to publish a report containing a list of VTP families, air drag families, Computational Fluid Dynamics (CFD) families, and tyre families with the highest risk of a deviation in the CO2 emission values. The Joint Research Centre’s (JRC) task is to perform the risk assessment analysis on behalf of the Commission. When assessing the risk, at least the elements mentioned in Article 3(2) of the Implementing Regulation need to be considered, when available. The GAAs must use the Commission’s risk assessment as a basis for selecting the families for their in-service verification.
This is the first annual report describing the methodology used for the risk assessment, and the main findings. The risk assessment methodology described is based on a Composite Risk Index (CRI), which combines the probability and severity of a specific occurrence. Probability levels are determined based on the total number of new vehicles, or tyres, that have been placed on the European Union market. Severity levels are determined based on the data collected pursuant to Reg. (EU) 2019/1242 and Article 22 (2) of Reg. (EU) 2017/2400.
This report presents the outcome of the ISV risk assessment for the VTP, air drag, and tyre families, identifying those with the highest risk of including vehicles with deviations in CO2 emissions values. Based on the assessment, 35 tyre families, 17 air drag families, 13 engine VTP families, and 4 transmission VTP families have been classified as high risk. No specific families have been identified for mass and AS tests, as there were no relevant indicators to consider in the risk assessment for these parameters. Nevertheless, these tests are still required within the scope of the HDV ISV. Vehicles selected for air drag and VTP testing can be used for the mass tests as well, while AS tests should be performed on vehicles selected for VTP testing. In addition, CFD family selection remains out of scope for the 2025 ISV, as this certification pathway is not yet in force.
To support the GAAs in the planning and selection of vehicles, components, and tyres for the 2025 ISV campaign, each identified ISV family is accompanied by its certification number and key technical specifications, that can assist authorities in sourcing the relevant vehicles, components, and tyres.
