This site has been developed by the OECD's Task Force on Pollutant Release and Transfer Registers (PRTRs). The purpose of this database is to share PRTR data as widely as possible within the OECD area by including 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 and not at the level 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. Due to differences between different PRTRs, such as the number and type of pollutants, sectors that are subject to reporting and the reporting thresholds, users are cautioned that it may be misleading to compare or rank countries based on the PRTR data presented in this database. Japan served as a lead country in the development of this website.
