Average CO2 emissions per km from new passenger cars

The indicator is defined as the average carbon dioxide (CO2) emissions per km by new passenger cars in a given year. The reported emissions are based on type-approval and can deviate from the actual CO2 emissions of new cars. In the monitoring for cars and vans, emissions data are reported using the ‘New European Driving Cycle’ (NEDC) protocol until 2019, using both protocols NEDC and the ‘Worldwide harmonized Light vehicles Test Procedure’ (WLTP) in 2020 and only WLTP protocol from 2021.

In this table, from 2020, reported WLTP data are shown; for the period 2017-2019 a conversion factor, calculated using 2020 data in NEDC and WLTP, is used to show data in WLTP; before 2017, NEDC data are shown.
