A Pollutant Release and Transfer Register (PRTR) is a publicly accessible database or inventory of chemicals or pollutants released to air, water and soil and transferred off-site for treatment. It brings together information about which chemicals are being released, where, how much and by whom. PRTRs provide a rich source of data for multiple uses and purposes. For facilitating better uses of PRTR data, this document compiles good practices of the data uses and tools for their presentation, which were gathered from member countries. It could illustrate the varied uses of PRTR data and encourage additional audiences to access PRTR data.
