This press release announces the European Commission's publication online of the first consolidated European inventory of pollution from small, scattered sources such as cars, airplanes, ships, household boilers and small farms. The inventory of EU-wide data on 'diffuse' pollution brings together for the first time information currently held in a range of different inventories. Until now detailed EU-wide emissions data have been compiled only for major industrial sources like factories and power stations. The inventory of diffuse pollution represents an important step towards the development of a future European Pollutant Release and Transfer Register (European PRTR).
