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

To ask the Secretary of State for Environment, Food and Rural Affairs, how many people have signed up to receive his Department's UK-Air email updates; and what the average engagement rate is for Tweets made from the @DefraUKAir Twitter account.

There are currently 309 subscribers to the UK-Air email bulletin service.

The UK-Air Twitter account currently has 6,697 followers. The average engagement rate for Tweets made from the Defra UK-Air Twitter account between 1 November 2016 and 31 October 2017 was 0.7%.

A five day forecast of predicted air pollution levels is continually updated on the UK-Air website, along with advice from Public Health England to allow members of the public, particularly those who are most likely to be affected by air pollution, to plan and take action.

Defra also issues email alerts to the health charity network during periods of elevated air pollution. These alerts provide full details of the nature of the air pollution episode along with links to further information, including specific health advice relevant to the episode.
