The LAEI 2016 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 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 forward to 2020, 2025, and 2030 will be available soon.
The area covered by the LAEI includes Greater London (the 32 London boroughs and the City of London), as well as areas outside Greater London up to the M25 motorway.
These emissions have been used to estimate ground level concentrations of key pollutants NOx, NO2, PM10 and PM2.5 across Greater London for year 2016, using an atmospheric dispersion model. Air pollutant concentration maps and associated datasets are available for download.
Due to the size of the LAEI database, datasets have been zipped and need to be downloaded in several parts.
Key GIS geographies and road traffic flows and vehicle-kilometres for 2010, 2013 and 2016 for each vehicle type. Data are provided in Excel and GIS formats.
Grid Emissions Summary
This dataset includes emissions of NOx, PM10, PM2.5 and CO2 in tonnes/year for 2010, 2013 and 2016 for each source category at a 1km grid square resolution, including summary tables for London boroughs and London zones (Central / Inner / Outer London). Data are provided in Excel and GIS formats.
Detailed Road Transport
Road transport emissions in 2010, 2013 and 2016 by vehicle type and also by pollutant. This data is presented at link level for major roads and at grid level for minor roads and cold start emissions. Data are provided in Excel and GIS formats.
This dataset includes modelled 2016 ground level concentrations of annual mean NOx, NO2, PM10 and PM2.5 in µg/m3 (microgramme per cubic metre) at 20m grid resolution. For PM10, it also includes the number of daily means exceeding 50 µg/m3.Data are provided in Excel, GIS and PDFs formats.
This dataset includes estimations of the number of Londoners and number of schools in London exposed to an annual average NO2 concentration above the Air Quality Strategy objective of 40µg/m3, based on the modelled 2016 ground level concentrations. A comparison with previous 2013 concentrations modelled for the LAEI 2013 inventory is also provided.
