Welcome to Ireland’s Pollutant Release and Transfer Register (PRTR).

The PRTR provides a publicly accessible and searchable database which members of the public can use to search for installations in Ireland that

  • release any of the 91 PRTR pollutants in excess of specific thresholds or in excess of specific thresholds or
  • make off-site transfers of non-hazardous and hazardous wastes that are above specified weight thresholds 

The register also fulfils requirements of the Aarhus Convention, as a simple means of giving access to information about the biggest producers of environmental emissions and waste movements.

The PRTR Register is updated annually. The current release shows data up to 2020.


The EPA maintains the PRTR database which lists in excess of 400 facilities that engage in environmentally hazardous activities, as defined in the E-PRTR Regulation, (EC) No 166/2006.

Each year, each concerned operator submits environmental reports to the Environmental Protection Agency (EPA). Every company that is the subject of information in the register has a licence, permit or registration for its activities and emissions.

The reporting of emissions and waste transfers through PRTR does not imply that a facility is causing environmental pollution, only that its activity belongs to a relevant PRTR sector.  EPA licensed operations, for example, are regulated and monitored by the EPA's Office of Environmental Enforcement in accordance with licence conditions, in a manner that is independent of PRTR.

The facility operators that are subject to reporting are required to assure the quality of the information that they report. The EPA then carries out detailed quality checks on the submitted data before reporting the required portion, as set out in the PRTR regulation, to the European Commission.

The EPA continually works to make the data reporting task more efficient for operators and to improve our data analysis and validation process to ensure all future data is as robust and accurate as possible.

Public information

The PRTR is intended to make it easier for citizens to gain information about emissions to the environment. Over the course of time, we will be adding more information and links.
