The Government recognises that short-term exposure to elevated levels of PM2.5 can impact health, particularly for vulnerable groups. This is why we provide alerts and advice during air pollution episodes to ensure people can access the information and health advice they need in order to minimise impacts. We are also taking action to increase public awareness about air pollution, including through an expanded £8 million funding pot which will be made available to local authorities through the Air Quality Grant scheme.

Under the Environment Bill, the Government will have a duty to bring forward a target for PM2.5 by October 2022. In setting our air quality targets, we have sought advice from the Committee on the Medical Effects of Air Pollutants (COMEAP) on whether the priority aim should be long-term exposure rather than short-term. COMEAP advised that a focus on long-term average concentrations of PM2.5 is most appropriate to deliver public health benefits. This advice has been published and can be accessed via this link: https://www.gov.uk/government/publications/fine-particulate-air-pollution-pm25-setting-targets.

The two air quality targets that we plan to set will focus on reducing the long-term exposure to PM2.5 and its associated health impacts, actions taken to achieve these targets will contribute to reducing average daily concentrations of PM2.5.
