Mr. Allan Roberts

To ask the Secretary of State for the Environment how many times carbon monoxide levels in London's air have exceeded World Health Organisation guidelines in the last 12 months; what steps he is taking to ensure that guideline breaches will not increase in the next 12 months; and what actions are in process to ensure that London's air does not exceed World Health Organisation guidelines for carbon monoxide or nitrogen dioxide levels during the next four years.

Mrs. Virginia Bottomley

The air quality monitoring data for London are being analysed to answer the hon. Member's specific question. I will provide a substantive answer when this analysis is completed.
