In the United States, for instance, the US Environmental Protection Agency (EPA) maintains the National Emissions Inventory (NEI), which contains estimates of emissions of 187 hazardous air pollutants, with information collected from state and local agencies down to the facility level (see EPA website: www.epa.gov/ttn/chief/net/2011inventory.html). The European Environment Agency (EEA) maintains the European Pollutant Release and Transfer Register (E-PRTR), which collects emissions data for 91 pollutants and also down to the facility level (http://prtr.ec.europa.eu/#/home).
