As of July 1, only the so-called Worldwide harmonized Light vehicles Test Procedure (WLTP) may be used to calculate the amount of the bpm amount for new cars. Despite earlier promises about the budget-neutral introduction of this, this sometimes results in higher prices for new cars, according to a letter to parliament on Friday.

For bpm it is important how high the CO2 emissions of a car are. However, the new tables that the government wants to use for this cause an increase in the tax, the car sector believes, and that was not agreed.

TNO had calculated that it was not too bad, but a counter-investigation by KPMG (commissioned by the car industry) showed that an increase would take place. The House of Representatives therefore demanded an additional independent investigation, which was recently promised.

The problem is that new cars have become heavier and more powerful, resulting in higher CO2 emissions. It would have nothing to do with a change of calculation method, according to the letter from State Secretary Vijlbrief of Finance that went to the House of Representatives on Friday.

Increase for some models

He bases this on research recently conducted by Professor Koopmans of the Free University at the request of the House of Representatives. "For all cars sold together, the conversion has been budget neutral and the total bpm revenue is not expected to change as a result of the conversion," the letter said.

That study would show that the bpm amount for the ten best-selling cars falls by an average of 10 percent. The twenty best-selling models have an average decrease of 6 percent.

The Ministry of Finance is advised to include more flexibility in the bpm table, as there is an increase for some models. For example, the bpm on a Peugeot 3008 increases by 24 percent, but it drops by 17 percent for a Renault Clio.
