To ask the Secretary of State for Transport what are the existing targets for acceptable noise levels of traffic in London; who is responsible for setting them; and if he will list those monitoring areas where they are being exceeded.

There are no such targets. However, the United Kingdom has recently secured EC agreement to lower limits for the noise standards to which individual vehicles are built; tighter standards for vehicles have reduced noise levels by up to 10 dB(A) over the last 10 years.
