This document discusses Pollutant Release and Transfer Registers (PRTRs) and their benefits. A PRTR is a central database that stores, manages, and validates pollution data provided by industries and governments. It disseminates this information to the public. PRTRs benefit governments by increasing efficiency and capacities, and benefit civil society and industry by empowering the public and involving industries. The document provides examples of PRTR legal frameworks and discusses how PRTR data can be presented through searchable databases, maps, trend graphs, and rankings to facilitate access to environmental information.
