Global Inventory of Pollutant Releases

Useful databases: Pollutant Release and Transfer Register


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


Centre for PRTR Data

The Centre for PRTR Data presents national PRTR data from OECD countries at one Internet location. The purpose is to include PRTR data from as many OECD countries as practicable and feasible on a national or regional level, but does not include PRTR data of individual sites of facilities. 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 the lead country in the development of this website. Download all data in the Database for 2001-2010 and for 2011-2019.


Resource Centre for Release Estimation Techniques

This online centre is a web-based clearinghouse of guidance manuals and other documents. It 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.

This website provides a global portal to 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 OECD, in cooperation with the United Nations Economic Commission for Europe (UNECE) and the United Nations Environment Programme / GRID-Arendal.
