To ask the Secretary of State for Transport, if he will publish the Government's data
on the level of NOx emissions and other pollutants produced by an (a) diesel and (b)
petrol car registered before 2005 driving at (i) 5mph, (ii) 10mph, (iii) 15mph, (iv)
20mph, (v) 25mph, (vi) 30mph, (vii) 40mph, (viii) 50mph, (ix) 60mph and (x) 70mph.
<p>The Government does not possess this specific data.</p><p> </p><p>The Vehicle Certification
Agency (VCA) has developed databases listing most of the cars and new vans available
for sale in the UK. These databases are available online and inform buyers about the
impact of the vehicle on the environment by giving fuel consumption information or
identifying those that use alternative fuel types; in the car database, identifying
the vehicle excise duty on individual vehicles based on their CO2 emissions; and in
the van database, helping buyers to choose the correct vehicle for their requirements.
The car database also provides information on the air quality pollutants and noise
levels recorded as part of type-approval process but these only confirm that the car
meets the required emissions standard and are not suitable for comparative purposes.</p><p>
</p><p>All national air quality monitoring data is available on the Government’s UK-Air
website, which provides in-depth information on air quality and air pollution in the
UK. A range of information is available, from the latest pollution levels, pollution
forecast information, a data archive, and details of the various monitoring networks.
This website is hosted and maintained by Ricardo Energy & Environment on behalf
of Defra and the Devolved Administrations.</p>
To ask the Secretary of State for Transport, whether he has made an assessment of
the potential merits of allocating departmental funding to support the development
of technology to filter toxic particles from vehicle exhausts at source to reduce
air pollution.
<p>No assessment has been made of funding options to meet exhaust emission requirements
as the technology to filter toxic particles from vehicle exhaust systems at source
has already been developed. New diesel vehicles in the UK are fitted with a Diesel
Particulate Filter (DPF) and have been for several years.</p>
