Question to the Department for Transport:

To ask Her Majesty’s Government whether they have made an estimate of the number of people in the UK who may die as a result of diesel emissions from VW cars above the regulatory limit; and if not, whether they will do so.

We are unable to estimate accurately the air quality impacts resulting from Volkwagen’s actions as we cannot quantify the additional emissions of the affected vehicles under all conditions of operation.

However we have made a comparison of the old software to the new ‘fix’ software under test track conditions. The results from tests on two Skoda vehicles indicate 30-40% lower NOx emissions with the new ‘fix’ software.
