Average CO2 emissions per km from new passenger cars (2000-2023)

The Regulation (EU) No 2019/631 requires Countries to record information for each new passenger car registered in its territory. 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. Since 2021, the emissions are measured with a new test procedure (Worldwide harmonized Light vehicles Test Procedure WLTP), compared to the New European Driving Cycle (NEDC) procedure used until 2020. The WLTP aims to reflect better real driving conditions and WLTP values are systematically higher than NEDC values. This change leads to a break in time series between 2020 and 2021.

Statement

EU average specific CO2 emissions are calculated as the average emissions (as recorded in the certificates of conformity, based on type approval values) of all new passenger cars first registered in the EU in a particular year. For calculating manufacturers/pools’ average emissions, eco-innovation savings and super-credits (for 2020-2022) are also taken into account.

For the purpose of EU SDG statistics, the NEDC emissions values for the years 2017, 2018 and 2019 have been converted into equivalent WLTP ones, using the 2020 dataset, which contains both values (NEDC and WLTP) for all individual vehicles. From 2021 only WLTP values are reported.

In the monitoring for cars and vans, emissions data are reported using NEDC protocol until 2019, using both protocols NEDC and WLTP in 2020 and only WLTP protocol from 2021. In this table, from 2020, 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.
