Make your local map by either entering in a postcode or
zooming in from the map of England & Wales.
After you click on the large map of England and Wales, the next screen you see is a smaller map showing major roads and urban areas. The RED DOTS show the locations of authorised processes.
Clicking on a red dot takes you to the list of industries and the authorisation numbers. Click on one of these to look at the data for annual emissions (releases). The data is organised by medium (air, land or water), year (1992, 1993 & 1994) and substance.
Much more detailed information, such as the authorisations issued to the industrial sites, under the system of "Integrated Pollution Control" (IPC), is available from Her Majesty's Inspectorate of Pollution.
