Lord Lewis of Newnham asked Her Majesty's Government:
Further to the Written Answer by the Lord Rooker on 9 October (WA 122-3), what are the percentages of the United Kingdom emissions of dioxins and furans from all sources.[HL7702]
The Minister of State, Department for Environment, Food and Rural Affairs (Lord Rooker): The UK National Atmospheric Emission Inventory (NAEI) provides a standard reference air emission inventory for a wide range of pollutants including dioxins emissions to air. The inventory can be found at www.naei.org.uk/.
The table below provides a summary of NAEI estimates of UK dioxin and furan emissions from each source category from 1990 to 2004. It also includes the estimated percent contribution from each source category to the total release of dioxins and furans to air for 2004, the most recent year for which statistics are available.
