Your air quality strategy clearly states that "Road transport is the dominant source of PM10 emissions in central London, contributing 83 per cent in 2006" and "Private vehicles ... are responsible for approximately 65 per cent of London's PM10 and NOx emissions." However, although tailpipe emissions may fall thanks to cleaner cars and increased numbers of electric vehicles, "tyre and brake wear emissions between 2006 and 2015 are not projected to decrease, due to the technical difficuties of tackling this source of emissions." Would you therefore like to see a reduction in the absolute numbers of private vehicles on London's roads?

The absolute number of vehicles in central London has already been reducing owing to ongoing initiatives like the Congestion Charging zones and TfL's continued promotion of smarter travel to encourage a shift to cleaner modes of transport. However, emissions of air pollutants on a per car basis are comparatively low, which is why some of the major proposals in the draft Air Quality Strategy, such as the Low Emission Zone, are focused on more individually polluting vehicles such as HGVs, coaches and buses.

The challenge going forward is to manage the tyre and brake wear emissions from all vehicles in London and that is why I am keen to work with central Government and the European Union to reduce emissions of PM by supporting the development of new technologies.
