London Atmospheric Emissions Inventory 2013

 Created 1 year ago, modified 2 months ago

The LAEI 2013 is the latest version of the London Atmospheric Emissions Inventory and replaces the previous versions.

Estimates of key pollutants (NOx, PM10, PM2.5 and CO2) are included for the base year 2013 and projected forward to 2020, 2025, and 2030. Emissions for previous years 2008 and 2010 are also provided, to allow comparison with previous versions of the LAEI.

The LAEI area covers the 32 London Boroughs and the City of London and up to the M25 motorway

Due to the size of the LAEI database this dataset has been zipped and needs to be downloaded in several parts.

0 - Documentation (.ZIP - 17.8 MB)

LAEI 2013 Methodology - NEW

1 - Supporting Information (.ZIP - 678.1 MB)

Key GIS geographies and road traffic flows and vehicle-kilometres.

2 - Grid Emissions Summary

Emissions by 1km grid square and source, for each inventory year as well as pivot tables to calculate borough and zone level statistics. Data is in Excel, Mapinfo and ArcGIS format.

  • Excel Files (.ZIP - 131.8MB) - 14/04/16 Update - Please note that the Excel files have been updated, and now include an additional Pivot Table providing a summary of Road Transport emissions by Borough. 26/01/2017 Update - Please note that Emissions Summary for other pollutants has now been added to this section.
  • GIS (Mapinfo) Files - (.ZIP - 212.5 MB) - 21/11/2016 Update - Please note that the Road Transport files for PM10 Major Roads have been updated.

3 - Detailed Road Transport

Road transport emissions by vehicle type at link level for major roads and grid level for minor roads and cold start emissions.

4 - Concentrations (.ZIP - 1.6 GB)

Modelled 2013, 2020, 2025 and 2030 concentrations of NO2, PM10 and PM2.5 at 20m grid level. 01/07/16 - Please note that future concentration files have now been included

Due to the size of this database we recommend working on a local drive rather than over a network.
