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 NO_x, NO₂, PM₁₀ and PM_2.5 emissions and ground level NO_x, NO₂ and PM concentrations already published as part of the LAEI 2019. It includes the following datasets, which can be downloaded below:

• 2019 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 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 and 2019, for NO_x, PM₁₀, PM_2.5 and CO₂
• Charts and tables of emissions by source type at borough level for NO_x, PM₁₀, PM_2.5 and CO₂, as reported in the dashboard of emissions. Additionally, a more detailed split of emissions for 2019 is provided in alternative charts.

Forward projections for 2025 and 2030 for all of the above will be available shortly.
