LAEI 2016 - Borough Air Quality Data for LLAQM

Following the release of the latest London Atmospheric Emissions Inventory (LAEI) 2016, 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 NO_x, NO₂, PM₁₀ and PM_2.5 emissions and ground level concentrations already published as part of the LAEI 2016. It includes the following datasets, which can be downloaded below:

Borough-specific data files containing:

• 2016 Maps of ground level concentrations across each borough for NO_x, NO₂, PM_2.5 (annual mean), and PM₁₀ (both annual mean and number of daily means over 50µg/m³). Maps are provided as JPEG 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 2010, 2013 and 2016, for NO_x, PM₁₀, PM_2.5 and CO₂

London-wide data files:

• A Source Apportionment (Excel) tool, providing a summary table and chart of emissions split by source at a chosen location (1km² resolution) and at borough level
• A summary table providing key borough level statistics in relation to population exposed to NO₂ concentrations above the Limit Values (40µg/m³ annual mean and 60µg/m³ annual mean as a proxy for the hourly mean Limit Value)
