Pollution inventory reporting
The pollution inventory provides information about releases and transfers of substances from regulated industrial activities.
The pollution inventory includes reporting on annual emissions of certain substances to air, controlled waters and land, and off-site transfers in wastewater and waste.
You must report to the pollution inventory if you:
- operate under a part A (1) environmental permit and have received a notice under Regulation 60 of the Environmental Permitting Regulations 2010
- operate a sewage treatment works with a capacity at, or over, 100,000 population equivalents
- dispose of radioactive waste to air, water or sewers covered by a permit issued under the Environmental Permitting Regulations 2010
- run an opencast mine or quarry with a surface area over 25 hectares, or an underground mine and related operation (no capacity threshold)
Returns must be submitted by 28 February of each reporting year. You can use the Environment Agency’s online reporting system, or complete and return a paper reporting form.
Resource efficiency
Operators no longer need to report resource efficiency data as part of their pollution inventory return. If you do submit data, it will not be used for any purpose.
For some sectors, there may be a specific benefit in continuing to collect resource efficiency information. Where this is the case, the Environment Agency will work with the relevant operators or trade associations to explore other options for collecting this data, for example through trade association corporate and social responsibility reporting schemes.

Pollution inventory: send an electronic return
This system will:
- check your information for mistakes
- automatically fill in standard fields
- allow you to look at information you have sent in previous years
The deadline for sending your pollution inventory data is 28 February each year.
If you think that some of the information you submit to the pollution inventory is confidential:
- tick the box in part 1 of PIEDC
- provide justification text for your claim
- tick the confidentiality box next to the appropriate lines of data
- send any supporting documents to your site inspector
The Environment Agency will make a decision on your claim for confidentiality within 20 days from the date of your application, or within a longer period if agreed.
If you do not enclose a written justification for each item included in the confidentiality claim, they are likely to reject it immediately.

Forms to report pollution inventory data. Use these forms if you cannot use the online PIEDC system.
