§ Sue Doughty
To ask the Secretary of State for Environment, Food and Rural Affairs what the annual dioxin emissions produced by(a) on-farm drum incinerators, (b) on-farm carcass incinerators and (c) waste oil burners were in each year since 1998. 
§ Mr. Morley
[holding answer 30 June 2003]: UK emission estimates are contained in the National Atmospheric Emissions Inventory and are published annually. Full NAEI data is available at the NAEI website www.naei.org.uk. UK dioxin emissions were estimated at 1,184 grammes (international toxic equivalent, I-TEQ) in 1990, and to have reduced from 424 grammes in 1998 to 357 grammes in 2001, the latest date for which data are available. The NAEI does not contain data at the level of detail requested. As regards on-farm drum incinerators, the total emissions from all small-scale waste burning are estimated at 50g per year I-TEQ, but this figure includes both agricultural and non-agricultural waste burning and is subject to considerable uncertainty. The total emissions from all small animal carcase incinerators are estimated at 0.25g per year I-TEQ. These figures have all remained constant between 1998 and 2001. There are no data on emissions from waste oil burners.
