Air quality summary statistics
Data for London air quality monitoring sites showing whether annual monitoring objectives were met for different species of pollutant. Data for 2016 includes the first two months of the year only so this is an indicative outlook. This data was accessed using the London Air API.
For some species, all monitoring sites taking measurements have met the monitoring objectives over the last decade. Note that the total number of sites measuring a given species changes from year to year. Here all sites are grouped together regardless of their type (e.g. roadside, suburban, industrial) or geographic location.
For other species, 60-100% of the monitoring sites taking measurements have met annual objectives over the last decade. All reportable sites are now compliant with the PM10 objective.
The percentage of sites meeting annual nitrogen dioxide monitoring objectives has shown relatively little change but there have been improvements in recent years.
The percentage of sites meeting annual monitoring objectives for ozone has fluctuated widely in the past but in recent years has increased.
