    London Average Air Quality Levels

    King's College London
    The data shows roadside and background average readings for Nitric Oxide, Nitrogen Dioxide, Oxides of Nitrogen, Ozone, Particulate Matter (PM10 and PM2.5), and Sulphur Dioxide. Measured in Micrograms per Cubic Meter of Air (ug/m3). The spreadsheet shows which Index level each reading falls in, and contains charts showing pollutant levels by time of day per month. Trend graphs of Nitrogen Dioxide and Particulate Matter PM2.5 are on the ...

    London Atmospheric Emissions Inventory (LAEI) 2010 Air Quality Focus Areas

    Greater London Authority (GLA)
    The LAEI 2010 has since been superseded. Click here for the full list of releases. There are 187 Air Quality Focus Areas in the Capital. These are locations that not only exceed the EU annual mean limit value for NO2 but are also locations with high human exposure. The Focus Areas were defined to address concerns raised by boroughs within the LAQM review process and forecasted air pollution trends. This is not an exhaustive list of Lon...

    Noise Pollution in London

    Department for Environment, Food and Rural Affairs
    This dataset maps noise pollution in London. Data is available for noise pollution from road and rail sources. The following shapefiles are available to download below: LAeq,16h: indicates the annual average noise levels for the 16-hour period between 0700 – 2300. Lden: indicates a 24 hour annual average noise level with separate weightings for the evening and night periods. Lnight: indicates night time annual average noise level ...

    London Energy and Greenhouse Gas Inventory (LEGGI)

    Greater London Authority (GLA)
    The London Energy and Greenhouse Gas Inventory (LEGGI) shows greenhouse gas emissions and energy consumption from homes, workplaces and transport within the Greater London area. It is produced on an annual basis to measure progress against the Mayor's carbon reduction targets for London. The LEGGI uses sub-regional energy (electricity, gas and other fuels) and carbon dioxide equivalent (CO2e) data published by the Department of Busines...

    Analysing Air Pollution Exposure in London

    Greater London Authority (GLA)
    Updated in Februrary 2017. Air quality in London has improved in recent years as a result of policies to reduce emissions, primarily from road transport. However, recently updated maps of pollution concentrations for 2013 (LAEI 2013) still show significant areas of exceedances of the annual mean NO2 EU Limit Values. Improvements are planned to address these, as recently announced in the Mayor’s package of air quality measures. The U...

    London Atmospheric Emissions Inventory (LAEI) 2006 Modelled Annual Mean Concentration NO2 2006 Values

    Greater London Authority (GLA)
    The LAEI 2006 has since been superseded. Click here for the full list of releases. Modelled NO2 annual mean concentrations in London for the year 2006. Calculations are based on the 2006 London Atmospheric Emissions Inventory (LAEI) and use three different meteorological scenarios (2003, 2004 and 2006). This dataset can be mapped in a Geographic Information System (GIS) using the corresponding 20m grid or point datasets also available...

    London Atmospheric Emissions Inventory (LAEI) 2006 Modelled Concentration Grid Points

    Greater London Authority (GLA)
    The LAEI 2006 has since been superseded. Click here for the full list of releases. Point locations at 20 metre grid spacing, used for mapping modelled concentration values for LAEI-2006 datasets. Points represent the centre of a 20m by 20m square and can be linked to modelled vales datasets using GRID-ID field. Due to the detailed nature of this dataset and the resulting large file size, the download file has been compressed (approx ...
