Improving air quality is an important issue for the City Corporation.

Our current Air Quality Strategy 2015-2020 (2MB) outlines the steps we are taking to achieve better air quality in the Square Mile.

In 2001 the Square Mile was designated as an Air Quality Management Area. Due to its location at the heart of London and the density of development, the City of London has some of the highest levels of pollution in the country. Poor air quality can harm human health and increase the incidence of cardiovascular and lung disease.

Progress with actions within the current City of London Air Quality Strategy are detailed in annual Air Quality Reports together​ with long term air quality data.

Updated Air Quality Strategy to be released September 2019

The Air Quality Strategy is now under review to update the action plan for the next five years. Thank you for all the consultation responses. The updated Strategy 2019-2024 will be released in September 2019. It will outline actions to be taken to continue to improve air quality in the Square Mile, in 6 policy areas:

  • Air Quality monitoring
  • Leading by example
  • Collaborating with others
  • Reducing emissions from road transport
