The LAEI 2013 is the latest version of the London Atmospheric Emissions Inventory and replaces the previous versions.
The LAEI 2013 was published in 2016. However, due to revised road transport emission factors (COPERT 5) the data has been further updated in April 2017 (see 4.1 and 6.1)
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.
