Exploring the potential of emergency measures to reduce air pollution during air pollution episodes

Air pollution episodes are defined as periods of a few hours or a few days when air pollution concentrations rise well above the normal range.

Emergency measures are ways in which a city can respond to air pollution episodes. They are used by many cities across Europe and further afield. This series of reports looks at the current evidence for the effectiveness of emergency measures and considers this in the London context.

This review includes four technical reports and an overview report which draws together the findings:

• Overview Report
• Report A – Health Effects of Short-Term Exposures to Air Pollution With Particular Reference to the Concentration Range on High and Very High Days
• Report B – Health Impacts of Air Pollution Episodes in London 2009-2017
• Report C – Effectiveness of short-term (emergency) actions to control urban air pollution – review of schemes
• Report D – Forecasting Accuracy for Emergency Measures
