LAEI 2019 - Borough Air Quality Data for LLAQM

Following the release of the latest London Atmospheric Emissions Inventory (LAEI) 2019, additional data has been produced at Borough level, to assist London boroughs with their LLAQM (London Local Air Quality Management) duties.

The data below is based on the NOx, NO2, PM10 and PM2.5 emissions and ground level NOx, NO2 and PM concentrations already published as part of the LAEI 2019. It includes the following datasets, which can be downloaded below:

• Maps of ground level concentrations across each borough for NOx, NO2, PM2.5 (annual mean), and PM10 (both annual mean and number of daily means over 50µg/m3) for years 2019, 2025 and 2030. Maps are provided as JPG and PDF files, and in two versions: one with an OS base map included (Conc2) and one without it (Conc1).
• Dashboards of emissions at borough level (tables and graphs) by source type for 2013, 2016, 2019, 2025 and 2030, for NOx, PM10, PM2.5 and CO2
• Charts and tables of emissions by source type at borough level for NOx, PM10, PM2.5 and CO2, as reported in the dashboard of emissions. Additionally, a more detailed split of emissions for 2019, 2025 and 2030 is provided in alternative charts.

Update 25 04 2023: Emissions and Concentration Maps for forecast years 2025 and 2030 have been added.
