Review: Commission Implementing Regulation (EU) 2026/1787 on Heavy-Duty Vehicle Emissions Monitoring
Commission Implementing Regulation (EU) 2026/1787 establishes a mandatory, standardized protocol for the empirical monitoring of CO2 emissions from heavy-duty vehicles by utilizing existing roadworthiness testing infrastructure. The regulation shifts emission verification from theoretical modeling to the collection of actual, real-world operational data.
Core Operational Requirements
- Data Collection Scope: Starting 1 July 2028, entities conducting roadworthiness tests are required to extract specific data points from vehicle on-board monitoring devices, specifically the Vehicle Identification Number (VIN), total odometer reading, test date, and lifetime fuel/energy consumption values.
- Reporting Cycle: Member States must aggregate and submit this data to the European Environment Agency (EEA) on an annual basis, with the first reporting deadline set for 30 November 2029.
- Technical Standards: Testing facilities are required to implement diagnostic tools compliant with Implementing Regulation (EU) 2025/2161 to ensure uniform data extraction across the Union.
Data Governance and Privacy
The regulation classifies the VIN as personal data and imposes strict data minimization and retention protocols:
- Retention Periods: Local testing bodies are mandated to delete the collected datasets within six months following their transmission to the EEA. The EEA is permitted to retain the data for a maximum of 20 years for longitudinal analysis.
- Transparency Obligations: Testing bodies acting as data controllers are legally required to provide vehicle owners with formal notice regarding the processing of their data, in full compliance with Articles 13 and 14 of the GDPR.

Commission Implementing Regulation (EU) 2026/1787 of 23 July 2026 laying down rules for the application of Regulation (EU) 2019/1242 of the European Parliament and of the Council as regards the detailed procedure for collecting real-world data relating to CO2 emissions from heavy-duty vehicles
Commission Implementing Regulation (EU) 2026/1787 establishes a standardized procedure for the collection of real-world fuel and energy consumption data from heavy-duty vehicles. By integrating this data collection into existing periodic roadworthiness tests, the Regulation aims to monitor the actual CO2 emission performance of vehicles throughout their operational lifetime. This framework ensures that the European Commission receives accurate, representative data to evaluate the effectiveness of emission standards while maintaining strict data protection protocols.
### Structure and Main Provisions
The Regulation is structured into four articles, supported by references to existing EU frameworks on roadworthiness and data protection. It functions as an implementing act under Regulation (EU) 2019/1242, specifically detailing the “how-to” of data retrieval.
* **Scope and Definitions:** It defines “real-world data” as the lifetime and static accumulated values extracted from on-board monitoring devices.
* **Collection Mechanism:** It mandates that, starting 1 July 2028, bodies performing roadworthiness tests must read out specific data—including the Vehicle Identification Number (VIN), odometer reading, and consumption data—during inspections.
* **Reporting:** Member States are required to transmit this aggregated data to the European Environment Agency (EEA) annually by 30 November, starting in 2029.
* **Data Protection:** The Regulation explicitly addresses the status of the VIN as personal data, assigning controller responsibilities to testing bodies and the EEA, and setting specific retention periods (6 months for local entities, 20 years for the EEA).
Compared to previous frameworks, this Regulation formalizes the transition from theoretical emission modeling to empirical, real-world verification, utilizing the existing infrastructure of roadworthiness testing to minimize administrative burdens.
### Key Provisions for Practical Application
For stakeholders and authorities, the following provisions are critical:
1. **Mandatory Data Points:** Testing centers must collect four specific data points: real-world consumption data, the VIN, the odometer reading, and the date of the test.
2. **Timeline:** While mandatory collection begins 1 July 2028 for vehicles registered from 1 July 2027, Member States have the option to begin voluntary collection as early as 1 January 2028.
3. **Technical Requirements:** Testing bodies must be equipped with tools capable of reading the on-board monitoring devices as specified in the related Implementing Regulation (EU) 2025/2161.
4. **Data Retention Limits:** The Regulation imposes strict “data minimization” rules. Local testing bodies and national authorities must delete the collected data six months after transmission to the EEA, ensuring that personal data is not stored longer than necessary for the reporting cycle.
5. **Transparency:** Controllers (testing bodies) are legally obligated to inform vehicle owners about the processing of their data in accordance with GDPR requirements (Articles 13 and 14).
**:** As this Regulation applies to the registration and roadworthiness testing of heavy-duty vehicles within the EU, it has direct implications for the transport and logistics sectors operating across the Union, including those involving Ukrainian carriers or vehicles registered in the EU by Ukrainian entities. Compliance with these technical and data-handling standards will be a prerequisite for the continued circulation and testing of heavy-duty vehicles within the European market.
