COPERT is the EU standard vehicle emissions calculator.


COPERT is the EU standard vehicle emissions calculator. It uses vehicle population, mileage, speed and other data such as ambient temperature and calculates emissions and energy consumption for a specific country or region.

Furthermore, COPERT is:

  • Internationally recognised — used by many European countries for reporting official emissions data.
  • A research tool — calculate emissions at a national, regional or local scale, and for annual to daily estimates.
  • Technologically advanced and transparent — COPERT’s methodology is published and peer-reviewed by experts of the UNECE LRTAP Convention.
  • Includes all main pollutants: greenhouse gases, air pollutants and toxic species.

The development of COPERT is coordinated by the European Environment Agency (EEA), in the framework of the activities of the European Topic Centre for Air Pollution and Climate Change Mitigation. The European Commission’s Joint Research Centre manages the scientific development of the model. COPERT has been developed for official road transport emission inventory preparation in EEA member countries. However, it is applicable to all relevant research, scientific and academic applications.

The COPERT methodology is part of the EMEP/EEA air pollutant emission inventory guidebook for the calculation of air pollutant emissions and is consistent with the 2006 IPCC Guidelines for the calculation of greenhouse gas emissions. The use of a software tool to calculate road transport emissions allows for a transparent and standardized, hence consistent and comparable data collecting and emissions reporting procedure, in accordance with the requirements of international conventions and protocols and EU legislation.
