Resource Centre for PRTR Release Estimation Techniques (RETs)

Development of this site

This site has been developed by the OECD's Task Force on PRTRs (Pollutant Release and Transfer Registers), which is part of the Environment, Health and Safety Programme. Canada served as a lead country in the development of this website, which is currently maintained by Finnish Environment Institute SYKE.

Purpose of the Resource Center

The site provides a clearinghouse of guidance manuals and documents on release estimation techniques available from the principal pollutant release and transfer registries developed by OECD member countries. The manuals and documents include descriptive information on the sources of pollution and the pollutants that are released to the environment, as well as information on emission factors, mass balance methods, engineering calculations, and monitoring information. To assist countries in the development, implementation, and the improvement of PRTR programmes, links to PRTR guidance documents are also provided.
