Question to the Department for Environment, Food and Rural Affairs:

To ask the Secretary of State for Environment, Food and Rural Affairs, what steps his Department is taking to reduce concentrations for pollutants in ambient air once the relevant limit value has been achieved.

Under the Air Quality Standards Regulations 2010 where levels of pollutants are below the set limit values, they must continue to be maintained. We have also set a Population Exposure Reduction Target for PM2.5, which will continue to reduce peoples’ average exposure across the country.

The Government is committed to working with local authorities and stakeholders to continue reducing air pollution and its harmful effects.
