Monitoring reports

Every year Greater Manchester publishes an Annual Status Report, which:

  • Outlines the strategies to improve local air quality and any progress made.
  • Gives a summary of local monitoring/modelling air quality data.
  • Reports on significant new developments that might affect local air quality.

See the latest status reports below.

EMIGMA is the Greater Manchester Emissions Inventory. The inventory contains information on the emissions of pollutants identified in the UK's Air Quality Strategy from all identifiable sources in the area. The emissions sources are grouped into three broad categories:

  • Stationary point sources - predominantly industrial processes.
  • Mobile line sources - road, rail and air transportation.
  • Area sources - other influential sources, such as domestic emissions, for which it is not practical to resolve to point or line representations but which are nevertheless collectively significant. These sources are essentially population based and include, for example, combustion and solvent usage related emissions from domestic houses.

The EMIGMA database covers an area of 1272 km2 encompassing the ten administrative districts of Greater Manchester.

The database allows the magnitude and spatial distribution of emissions across Greater Manchester to be investigated and enables the relative importance of different sources of air pollution to be examined.

The emissions data has a further role in providing the basis for dispersion modelling exercises and air quality management planning.

In conjunction with transport models it also provides the basis for forecasting air quality and determining the effects of changes in land use planning and transportation policies.
