9.5 Emissions of CO2, PM10 and NOx from ground-based transport <strong>in</strong><br />
<strong>London</strong><br />
Introduction<br />
This section provides provisional updated estimates of the trends <strong>in</strong> key<br />
greenhouse gas and local air quality pollutants from ground-based transport <strong>in</strong><br />
<strong>London</strong> between 2008 and 2013.<br />
The data reflect early results from TfL’s update to the <strong>London</strong> Atmospheric<br />
Emissions Inventories, which is currently near<strong>in</strong>g completion. The data <strong>in</strong> this<br />
section are therefore presented on a provisional basis. Full details of the updated<br />
<strong>in</strong>ventories will be published dur<strong>in</strong>g 2016, and the data made available to air quality<br />
practitioners.<br />
What is the LAEI?<br />
The LAEI provides estimates of the annual emissions of a wide variety of pollutants<br />
<strong>in</strong>clud<strong>in</strong>g NO x , PM 10 and CO 2 , from many different sources with<strong>in</strong> <strong>London</strong>. These<br />
sources <strong>in</strong>clude ground-based transport (road transport, shipp<strong>in</strong>g, rail and aviation),<br />
along with other emissions from domestic and commercial gas use, <strong>in</strong>dustrial<br />
sources, and Non-Road Mobile Mach<strong>in</strong>ery (NRMM) related to construction<br />
activities.<br />
The LAEI2013 provides Excel and GIS files of emissions over grids, which represent<br />
the GLA and areas roughly with<strong>in</strong> the M25. The emissions for the years 2008, 2010,<br />
2013, 2020, 2025 and 2030 are <strong>in</strong>cluded. Emissions from each source can be<br />
