The main instrument here is the renewal of the existing fleet, i.e. the replacement of older diesel vehicles with higher nitrogen oxide emissions. These exchange premiums are offered by international manufacturers with great success.
According to the VDIK’s own calculations, more than 500,000 diesel cars complying with the Euro5 emission standards and worse have disappeared from the fleet in 2017 and 2018 as a result of these measures. Without the promotion of renewal of the existing fleet, a decline in Euro5 diesel cars and worse by around 1.5 million would have been expected in 2017 and 2018. In fact, however, the number of cars in circulation fell by just under 2 million and thus by around 500,000 units more than expected. This effect is attributable to the changeover premiums.
