The OECD brings you publications and data on Pollutant Release on Transfer Registers (PRTRs) and presents a tool to explore trends in global releases.
Exploring data from multiple PRTRs simultaneously provides input on the global picture of pollutant releases. Use the filters above the set of figures below to explore PRTR data by country, pollutant, or sector. Note that this beta presentation of the data includes air and water release data from seven PRTRs and 14 pollutants; it does not include all PRTRs, all pollutants reported to these PRTRs, or releases to land.
The data presented in the charts below can be downloaded by clicking on the CSV button under the figures.
To access the full datasets from each of the PRTRs, including all reported chemicals, sectors, and release pathways, go to the PRTR Data Centre via Internet Explorer or Firefox or download all the data in Excel here.
The purpose of the PRTR Data Centre is to share PRTR data as widely as possible within the OECD area. 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.
Most of the PRTR systems established to date were designed to meet the needs of a specific country or region, with less attention being given to the comparability of the data among different PRTRs. Consequently, PRTRs have differing reporting requirements. Their respective differences confound integration of data across PRTRs and hamper comparative analyses of the data. When compiling and analysing data across multiple PRTRs, users must consider the impacts of these differences on the results. The most significant differences are in the reporting thresholds, sectors or activities covered, and pollutants covered by each PRTR.
See OECD’s Using Pollutant Release and Transfer Register (PRTR) Information to Evaluate Progress Towards the United Nations’ Sustainable Development Goal 12 for more information on these factors to consider when reviewing these data.
The Centre for PRTR Data presents national PRTR data from OECD countries at one Internet location (IE & Firefox are recommended). Users can create a report of PRTR data according to years, countries, regions, industry sectors, chemicals, etc. Japan, as a lead country, maintains this website. All data in the Database can also be downloaded from the ‘Access the data’ section above.

This online centre is a web-based clearinghouse of available guidance documents on release estimation techniques among OECD countries. Users can filter the list of documents by countries, target sectors, languages, etc. The OECD maintains this website.

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 is maintained by the OECD, in cooperation with the UNECE.

The OECD examined the sectors covered by PRTRs around the world to develop a harmonised list of the reporting sectors that are common to most PRTRs. The findings are presented in the Harmonised List of Sectors. It describes the methods used and resulting lists and provide the harmonised sector lists in a format that others can use for developing their own pollutant lists or for conducting multi-country analyses. The new pollutant list is currently being reviewed and will be posted soon.

The OECD has developed publications to assist countries in developing, implementing, and improving PRTRs, and to provide guidance to stakeholders in understanding and applying PRTR data. A number of OECD Council acts in force are dedicated to chemical safety including two Council Acts on PRTRs.
