About the Air Quality Strategy

Levels of nitrogen dioxide and fine particles are higher than health targets, so the Square Mile has been designated as an Air Quality Management Area. Poor air quality can harm human health and increase the incidence of cardiovascular and lung disease.

The City of London Corporation’s Air Quality Strategy outlines the steps we are taking to achieve better air quality in the Square Mile. Progress with actions in the Strategy are detailed in the annual Air Quality Reports together​ with long term air quality data.

The main aim of the Strategy is for over 90% of the Square Mile to meet the targets for nitrogen dioxide by 2025.

In 2020, 93% of the Square Mile was within Nitrogen dioxide annual air quality limits, compared to 67% in 2019 and 30% in 2018.

"“These plans will lead to a significant improvement in the Square Mile’s air quality. Londoners demand clean air. We are determined to ensure that the City Corporation continues to play a leading role in the UK’s drive to meet air quality standards. Our work is already having a positive effect, and we will continue to push for change, embracing new and ambitious approaches to tackling this health crisis.”"
