WHAT IS EMIT USED FOR?

EMIT is an Emissions Inventory Tool. EMIT can be used to store, manipulate and assess emissions data from a variety of sources. Emissions data held in EMIT can be used for:

• Local air pollution studies of toxic pollutants;

• Greenhouse Gas emissions inventories;

• Estimating emissions for use in IPPC applications; and

• Road traffic noise mapping studies.

The data used in all these environmental assessments must be consistent and traceable – EMIT can help to do this.

EMIT is particularly useful for emission-reduction scenario testing, for example to investigate the effect of Low Emission Zones and Home Zones in urban areas, and ways of reducing Greenhouse Gas emissions as a step towards meeting Agenda 21 or Kyoto targets.

Source Types
EMIT can store emissions data from a variety of sources. These broadly fall into two categories. Firstly there are the explicit sources such as:

• major roads,

• rail and

• industrial sources (point and area).

Secondly, EMIT can hold data from sources that may be too small to be considered explicitly, and instead are treated as average emissions on a 1 km² grid, such as:

• minor road,

• commercial, and

• domestic sources.
