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

To ask the Secretary of State for Environment, Food and Rural Affairs, how many air pollution alerts were issued between March 2024 and March 2025 by his Department's UK-AIR alerts when thresholds within Air Quality Standards Regulations (2010) were exceeded; on which dates; and how many unique visitors accessed the Daily Air Quality Index forecast webpage during that period.

Air pollution alerts are issued when thresholds within the Air Quality Standards Regulations (2010) for Ozone, Sulphur Dioxide or Nitrogen Dioxide are exceeded. The last time one of these alerts was issued was September 2023. ~ 2000 unique visitors accessed the DAQI during that alert.

Visitors to UK Air can also sign up to receive email bulletins providing a summary of the last hour or 24 hour’s air quality measurement data; daily updated forecasts of UK air pollution concentrations and notifications if the Alert Threshold in an Air Quality Daughter Directive is exceeded.
