According to the LAEI 2019, there are 160 Air Quality Focus Areas in London. The Focus Areas are locations that not only exceed the EU annual mean limit value for NO2 but are also locations with high human exposure. They were defined to address concerns raised by boroughs within their Local Air Quality Management (LAQM) review process and forecasted air pollution trends. This is not...

The LAEI 2019 is the latest version of the London Atmospheric Emissions Inventory and replaces previous versions of the inventory. Emissions estimates of key pollutants (NOx, PM10, PM2.5 and CO2) by source type are included for the base year 2019 and forecast years 2025 and 2030. Emissions for previous years 2013 and 2016 have also been revised, using the latest data...

The LAEI 2016 has been superseded. Click here for the full list of releases. Emissions estimates of key pollutants (NOx, PM10, PM2.5 and CO2) by source type are included for the base year 2016. Emissions for previous years 2010 and 2013 have also been recalculated, using the latest data sources (emission factors, activity data, ...) and methodology. Emissions projected...

This study estimates the long-term health impacts of exposure to air pollution in London from 2016 to 2050. The study finds that by 2050 policies in the London Environment Strategy (including the central London Ultra Low Emission Zone and expansion to the North and South circular roads) will result in: almost 300,000 Londoners avoiding new diseases attributable to air pollution,...

(Minor update on 07/11/2019, following feedback from Hillingdon. Hillingdon Pump Lane Focus Area has been included in the Hayes Focus Areas) According to the LAEI 2016, there are 183 Air Quality Focus Areas in London. The Focus Areas are locations that not only exceed the EU annual mean limit value for NO2 but are also locations with high human exposure. They were defined to address concerns...

The data shows roadside and background average readings for Nitric Oxide, Nitrogen Dioxide, Oxides of Nitrogen, Ozone, Particulate Matter (PM10 and PM2.5), and Sulphur Dioxide. Measured in Micrograms per Cubic Meter of Air (ug/m3). The spreadsheet shows which Index level each reading falls in, and contains charts showing pollutant levels by time of day per month. Trend graphs of...

This is a dataset of air quality exposure data broken down by parliamentary constituency based on the current 2013 data from the London Atmospheric Emissions Inventory. The legal limit for NO2 is an average annual concentration of 40 ug/m3.

These new borough packages provide a set of maps, data and graphs for the updated LAEI 2013. Their aim is to facilitate the usability of LAEI 2013 data.   Modelling and emission data from the LAEI 2013 update has been used for NOx, NO2, PM10, PM10d and PM2.5.   All boroughs can download the following files:   Excel Tools - These tools are currently under construction and will be available...

Updated in Februrary 2017. Air quality in London has improved in recent years as a result of policies to reduce emissions, primarily from road transport. However, recently updated maps of pollution concentrations for 2013 (LAEI 2013) still show significant areas of exceedances of the annual mean NO2 EU Limit Values. Improvements are planned to address these, as recently announced in the...

There are 187 Air Quality Focus Areas in London. These are locations that not only exceed the EU annual mean limit value for NO2 but are also locations with high human exposure. The Focus Areas were defined to address concerns raised by boroughs within the LAQM review process and forecasted air pollution trends. This is not an exhaustive list of London’s...
