Where to find Industrial Pollution (Pollution Inventory) data

What's in your Backyard service closing

As part of this decommissioning the Industrial Pollution (Pollution Inventory) data will be removed on Thursday 27 July 2017.

 

The Pollution Inventory data is available to download under an Environment Agency Conditional Licence from DATA.GOV.UK 

How to download and use data

 

 

The Pollution Inventory (PI) provides information on emissions of chemical pollutants from industrial sites in England regulated by us.

We record pollution released into the environment by industrial sites under the EC Integrated Pollution Prevention and Control Directive (IPPC).

Operators must measure or make an estimate of the amount of emissions of each controlled substance every year. They must also specify notifiable releases in a year. Notifiable releases are where there has been an emergency, mis-management, accident or plant failure which has caused pollutants to be released. 

Where the emissions exceed a set threshold for a substance, the operator must report this. If the emission falls below the threshold level this is indicated by “< (less than) threshold value”.

Since 1998, the data has been collected systematically on an annual basis to include all emissions of a specified list of pollutants. Emissions to air, water and sewers are reported. Data is also collected on wastes that are transferred off-site to a disposal or recycling facility.

Data from major industry such as power stations, chemical works and the metal and mineral industries has been collected since 1998. Data from landfill sites and waste transfer stations started being reported in 2002. Data from sewage treatment works was first collected in 2000, but only from the largest works for a limited number of substances. In subsequent years, data for smaller sewage treatment works has been collected for the full list of Pollution Inventory substances.

Sites that dispose of radioactive substances began reporting their radioactive emissions in 2000, but reporting only became compulsory in 2004. These organisations include nuclear power stations, universities and hospitals.

The data is supplied each year by the industrial operator as a legal requirement. We then verify and audit it to confirm that it is correct, prior to publication on this website.  

Why do we monitor pollution in this way?

Pollution from industry is controlled under a number of EC directives, one of the most important is the Integrated Pollution Prevention and Control Directive (IPPC). The aim of this legislation is to reduce pollution consistently across Europe.. In England and Wales IPPC is implemented at through the Environmental Permitting Regulations 2008, which were made under the Pollution Prevention and Control Act 1999.

These regulations divide polluting industry into various parts depending on how much of a polluting impact the industry could have. We regulate the Part A1, more polluting industries.

These include:

  • Fuel and power production
  • Metal production and processing
  • Mineral industries
  • Chemical industries 
  • Waste landfill sites 
  • Waste treatment, transfer and storage sites 
  • Other industries such as paper, pulp and board manufacturing and tar and bitumen activities

These are the industries that will submit their emissions report to the Pollution Inventory. The inventory also includes emissions from sewage treatment works and sites which use radioactive materials.

Local authorities regulate Part A2 and Part B, less polluting industries and the Pollution Inventory does not contain data for these.
