What does the PRTR (Pollutant Release Transfer Protocol) cover?

The register contains annual data reported within the following 9 industrial sectors:

  • energy
  • production and processing of metals
  • mineral industry
  • chemical industry
  • waste and waste water management
  • paper and wood production and processing
  • intensive livestock production and aquaculture
  • animal and vegetable products from the food and beverage sector, and
  • other activities.

Data is provided in the register for 102 pollutants falling under the following 7 groups:

  • Greenhouse gases
  • Other gases
  • Heavy metals
  • Pesticides
  • Chlorinated organic substances
  • Other organic substances
  • Inorganic substances.

A facility has to report data under PRTR if it fulfils the following criteria:

  • the facility falls under at least one of the 65 PRTR economic activities listed in Annex I of the Regulation and exceeds at least one of the PRTR capacity thresholds
  • the facility transfers waste off-site which exceed specific thresholds set out in Article 5 of the Regulation.
  • The facility releases pollutants which exceed specific thresholds specified for each media - air, water and land - in Annex II of the PRTR Regulation.

The data to be reported annually by each facility for which the applicable thresholds are exceeded are the following:

  • Releases to air, water and land of any of the 102 PRTR pollutants;
  • Off-site transfers of any of the 102 PRTR pollutants in waste water destined for waste-water treatment outside the facility;
  • Off-site transfers of waste (reported as tonnes per year) for recovery or disposal. For transboundary movements of hazardous waste outside the reporting country, details of the waste receivers have to be provided.

The reported releases include any introduction of any of the listed pollutants into the environment as a result of any human activity, whether deliberate, accidental, routine or non-routine, at the site of the facility.

PRTR also contains information on releases from diffuse sources into water which will be upgraded and extended gradually.

How are the data reported?

Data are reported by individual facilities to the relevant competent authorities on an annual basis. The respective authorities in the countries compile and check the quality of the reported data. The data are then provided to the Ministry of Environment and State Ecological Inspectorate for compilation and dissemination on this PRTR website. Detailed information on the reporting procedures and content is available in the PRTR Guidance Document .

In a first step, detailed feedback was provided to operators concerning the quality of the PRTR data. The checks covered an evaluation of the number of facilities and release reports, amounts of releases and transfers reported, confidentiality claims, accidental releases, etc.

As second step, the PRTR data were put into context with data reported under the Convention of Long Range Transboundary Air pollution, United Nation Framework Convention on Climate Change. The aims is to highlight differences and potential inconsistencies between data reported under different reporting obligations on the basis of which reporting operators can correct their deliveries whereas errors are found.
