| Publication | 13 May 2026 |
| Entry into force | 5 September 2025 (date of the corrected standard) |
| Affected parties | Manufacturers of M1 vehicles (cars) and N1 vehicles (light vans), suppliers of OBFCM and OBM systems, type-approval authorities |
| Category | European Regulation |

| Legal basis | Regulation (EU) 2024/1257 of the European Parliament and of the Council |
Manufacturers of cars and light vans, together with their electronic component suppliers, must review the corrected technical requirements of the Implementing Decision (EU) 2025/1707. This correction, published on 13 May 2026, corrects technical and drafting errors in the original text published on 5 September 2025, without altering the regulatory substance.
The corrected standard implements Regulation (EU) 2024/1257 and establishes the methods, requirements and tests applicable to on-board fuel and energy consumption monitoring devices (OBFCM), on-board monitoring systems (OBM), driver warning systems and the Environmental Vehicle Passport (EVP).
What does this regulation establish?
The correction affects five distinct technical areas within Implementing Decision (EU) 2025/1707:
| Corrected area | Description |
|---|---|
| OBFCM devices | Specific methods, requirements and tests for on-board fuel and energy consumption monitoring devices |
| OBFCM compliance limits | Correction of compliance limits applicable to these devices |
| OBM systems | Requirements and tests for on-board monitoring systems |
| Driver warning systems | Characteristics, performance and evaluation methods for driver warning and alert system operation |
| Environmental Vehicle Passport (EVP) | EVP format and data, and EVP data transmission methods for M1 and N1 vehicles |
The correction does not introduce new obligations or modify the regulatory scope. Its function is to ensure that the text published on 5 September 2025 correctly reflects the intended technical specifications, eliminating possible drafting or transcription errors that could generate incorrect interpretations during type-approval and verification processes.
Economic and operational impact
Although this is a technical correction without change in regulatory substance, the operational impact for manufacturers and suppliers is real: any type-approval, certification or audit process that has been initiated using the original text of 5 September 2025 as reference must be verified against the corrected text.
The main operational impact areas are:
- Technical documentation review: Type-approval files that include OBFCM or OBM specifications must be compared with the corrected text to detect possible discrepancies.
- EVP data systems update: The format and transmission methods of the Environmental Vehicle Passport have been corrected. EVP data generation and transmission systems must be adjusted to the final text.
- Compliance limits verification: Compliance limits for OBFCM devices have been subject to correction. Engineering and type-approval teams must confirm that their systems comply with the corrected values, not those in the original text.
- Coordination with suppliers: Vehicle manufacturers must communicate the changes to their OBFCM and OBM system suppliers to ensure the conformity of supplied components.
Who does it affect?
- M1 vehicle manufacturers: Cars and passenger vehicles with up to 8 seats in addition to the driver.
- N1 vehicle manufacturers: Light vans and goods transport vehicles with a maximum mass of up to 3,500 kg.
- OBFCM system suppliers: Companies that develop or supply on-board fuel and energy consumption monitoring devices.
- OBM system suppliers: Companies that develop or supply on-board monitoring systems.
- Type-approval authorities: Entities responsible for the verification and certification of M1 and N1 vehicles in the European Union.
Practical example
A car manufacturer (M1 category) that in October 2025 initiated the type-approval process for a new model, basing its technical documentation on the original text of Implementing Decision (EU) 2025/1707 published on 5 September 2025, must now review whether the compliance limits of its OBFCM devices and the format of the EVP data it has configured in its systems correspond to the corrected text or the original text.
If the corrected errors affect, for example, the numerical values of compliance limits or the EVP data scheme, the manufacturer will need to update both its type-approval documentation and its system parameters before the vehicle passes the technical inspection of type. Ignoring the correction and working with the original text could generate non-conformities in the type-approval process.
What should companies do now?
- Download the corrected text: Obtain the corrected version of Implementing Decision (EU) 2025/1707 from the EU Official Journal and compare it with the original text of 5 September 2025.
- Identify specific changes: Locate which technical specifications have been modified in the five affected areas: OBFCM methods, compliance limits, OBM systems, driver warning systems and EVP format.
- Review ongoing type-approval files: Verify that technical documentation submitted or being prepared to type-approval authorities reflects the corrected text, not the original.
- Update EVP data systems: Confirm with engineering teams that the format and transmission methods of the Environmental Vehicle Passport data comply with the corrected specifications.
- Communicate with affected suppliers: Communicate the changes to OBFCM and OBM system suppliers so they can verify the conformity of their components with the final text.
- Document the review: Record internally that verification of conformity with the corrected text has been carried out, as evidence for possible audits or
