Monitoring and reporting the CO2 emissions of heavy-duty vehicles



Regulation (EU) 2018/956 — monitoring and reporting CO2 emissions from, and fuel consumption of, new heavy-duty vehicles


It aims to:

  • allow transport companies to make well-informed purchasing decisions by giving them access to standardised information on fuel consumption in order to compare different models of lorries, trucks and buses;
  • encourage manufacturers to develop more energy-efficient heavy-duty vehicles (HDVs);
  • enable public authorities to design and implement policies to promote more fuel-efficient heavy-duty vehicles, for instance through taxation and road-user charging.



The regulation applies to heavy-duty vehicles, which include lorries, buses and coaches.

Monitoring and reporting

  • From 1 January 2019, and for each subsequent calendar year, EU countries must monitor certain registration data for new HDVs registered for the first time in the EU.
  • From 2020, EU countries must submit such data to the European Commission each year in accordance with a standard reporting procedure.
  • Manufacturers must also monitor and report each year to the Commission the CO2 and fuel consumption values, as well as additional relevant data, ​​for each new heavy-duty vehicle, as determined in accordance with Commission Regulation (EU) 2017/2400 (known as the Certification Regulation).
  • The regulation sets out the starting years of monitoring and reporting by manufacturers for each category of HDV.

Central register

  • The data provided by EU countries and manufacturers will be set out in a publicly accessible central EU register.
  • Exceptions to public accessibility must be justified by the need to protect private data and to ensure fair competition.

On-road verification tests

  • The Commission will monitor, where available, the results of on-road tests, performed under Regulation (EC) No 595/2009 — Emissions from heavy-duty vehicles (Euro VI), which are meant to verify that the CO2 emission and fuel consumption values determined according to Commission Regulation (EU) 2017/2400 correctly reflect the performance of HDVs.


  • The Commission can impose a fine where it finds that the data reported by the manufacturer does not match the data determined in accordance with Regulation (EC) No 595/2009, or where the data are not submitted within the applicable deadline.
  • The fine must be effective, proportional and dissuasive and must not exceed €30.000 per heavy-duty vehicle concerned.


It has applied since 29 July 2018.
