Pollutant release and transfer register

Useful databases: Pollutant Release and Transfer Register


OECD has developed three databases in order to encourage governments and other stakeholders to share PRTR data and technical information.   



This website provides a global portal to Pollutant Release and Transfer Register (PRTR) information and activities from countries and organisations around the world. The website aims to assist countries in the development, implementation and improvement of PRTR programmes.

It has been developed and is maintained by the Task Force on Pollutant Release and Transfer Registers (PRTRs), in cooperation with the United Nations Economic Commission for Europe (UNECE) and the United Nations Environment Programme / GRID-Arendal.


Centre for PRTR Data

The Centre for PRTR Data presents national PRTR Data from OECD countries at one Internet location. The purpose of this database is to share PRTR data as widely as possible within the OECD area, consistent with the OECD Council Recommendation C(96)41/Final, as amended by C(2003)87. The purpose is to include PRTR data from as many OECD countries as practicable and feasible. PRTR data included in this database is compiled on a national or regional level. The database does not include PRTR data of individual sites of facilities. This database will be updated on a regular basis to include additional and new data that has been made available. Users can create a report of PRTR data according to years, countries, regions, industry sectors, chemicals, types of release sources, and types of releases and transfers.  Japan served as a lead country in the development of this website.


Resource Centre for Release Estimation Techniques

This online centre provides information on available release estimation techniques, overarching documents and general information among OECD countries for estimating releases from various sources.  Canada served as a lead country in the development of this website, which is now maintained by Finnish Environment Institute, SYKE.
