Online maps published by the  European Pollutant Release and Transfer Register (E-PRTR), allow users to pinpoint the key environmental data and the main sources of air pollution from industrial facilities across Europe. The European Pollutant Release and Transfer Register (E-PRTR) is the a Europe-wide register that provides easily accessible key environmental data from industrial facilities in European Union Member States and in Iceland, Liechtenstein, Norway, Serbia and Switzerland. It replaces and improves upon the previous European Pollutant Emission Register (EPER). The register contains data reported annually by some 28,000 industrial facilities covering 65 economic activities across Europe. The interactive map shows where certain pollutants are released from individual industrial plants. . The Europe-wide register aims to help Europeans actively engage in decisions affecting the environment. The map search option provides a geographical approach to the E-PRTR data. The map can even be viewed here in maximized version.
