What is CO2MPAS?¶
CO2MPAS is backward-looking longitudinal-dynamics CO2 and fuel-consumption simulator for light-duty M1 & N1 vehicles (cars and vans), specially crafted to estimate the CO2 emissions of vehicles undergoing NEDC testing based on the emissions produced WLTP testing during type-approval, according to the EU legislations 1152/EUR/2017 and 1153/EUR/2017 (see History section, below).
It is an open-source project (EUPL 1.1+) developed for Python-3.6+. It runs either as a console command or as a desktop GUI application, and it uses Excel-files or pure python structures (dictionary and lists) for its input & output data.
The European Commission has introduced the WLTP as the test procedure for the type I test of the European type-approval of Light-duty vehicles as of September 2017. Its introduction has required the adaptation of CO2 certification and monitoring procedures set by European regulations (443/2009, 510/2011, 1152/EUR/2017 and 1153/EUR/2017). European Commission’s Joint Research Centre (JRC) has been assigned the development of this vehicle simulator to facilitate this adaptation.
The European Regulation setting the conditions for using CO2MPAS can be found in the Comitology Register after its adoption by the Climate Change Committee which took place on June 23, 2016, and its 2nd vote for modifications, in April 27, 2017.
