CO2 Model for PAssenger and commercial vehicles Simulation

CO2MPAS is used to analyse the correlation between the CO2 emissions from the Worldwide harmonized light vehicles test procedure (WLTP) and the New European Driving Cycle (NEDC) test procedures. The WLTP is a new test procedure developed at the UN/ECE level that the Commission has introduced (in the place of the NEDC) for the type-approval of passenger cars and light commercial vehicles starting on September 1st, 2017 (EU Regulation 1151/2017).  The CO2MPAS model is used by vehicle manufacturers and type-approval authorities during the WLTP phase-in (2017-2020), to calculate the equivalent NEDC CO2 emissions for vehicles tested on the WLTP. In this way, the CO2 emission targets set by Regulation (EU) 2019/631 can remain unchanged in spite of the introduction of the new procedure.

Commission Implementing  Regulations 2017/1152 and 2017/1153 provide for the use of CO2MPAS during the vehicle type-approval process.

An extended version of CO2MPAS has been used in the Impact Assessment for the “Review of Regulations setting emission performance standards to establish post-2020 targets for cars and vans" (see [1]) in order to calculate the baseline 2015 CO2 emissions from the European fleet of new passenger cars under WLTP conditions.

CO2MPAS to the Commission Roadmap:

• Primary:
  • CO2MPAS can also be used to provide “Data, analysis and intelligence for the Energy Union: initiative pooling and making easily accessible all relevant knowledge in the Commission and Member States”
• Secondary:
  • CO2MPAS can be used in the “Master Plan for the deployment of Cooperative Intelligent Transport Systems”. In particular CO2MPAS can serve as a reference simulation platform, for testing optimization of transport and logistics system in specific cases [2].

The model has been already presented to several international conferences and the results from its use published in different scientific journals and JRC reports.
