Commission's first report on actual CO2 emissions of cars and vans using data from on-board fuel consumption monitoring devices

First data from a sample of 600,000 cars suggests that actual fuel consumption and CO emissions ₂ of diesel and gasoline vehicles on the road are approximately 20 % higher than the official values from the used standardized WLTP type approval test. for regulatory purposes. This discrepancy is in line with what the Commission expected.

In the case of plug-in hybrid electric vehicles, the actual CO emissions were ₂ on average 3.5 times higher than laboratory values, which confirms that these vehicles are currently not reaching their potential, mainly because they do not charge and drive fully electric. often as expected.

As the data set expands in the coming years and its representativeness of the evolving fleet improves, it will be possible to determine how the gap will develop and whether further steps should be taken to prevent it from widening. (More on climate.ec.europa.eu)
