Ammonia is a gas that is directly emitted from livestock and from manure and slurry.
It can directly damage vegetation and contributes to eutrophication and acidification of sensitive habitats. See 'Ammonia and nature conservation' under the factsheets heading on this page, for more information. Farms that are close to wildlife sites may have additional permit improvement conditions to produce an emission reduction plan to reduce ammonia emissions.

The following factsheets relate to how we assessed ammonia emissions for permits issued during 2007/2008 - they are not applicable for new applications or variations to expand existing permits. The emission factors in these documents have been revised and should not be used.

Workshops
We ran workshops for farmers with emission reduction improvement conditions in 2008. You can download the presentation we gave below.
