Losing derogation could force one in eight families out of dairying

The assessment concluded that the loss of derogation would result in a €45bn cumulative loss in economic output between 2026 and 2035.

Industry figures warn that losing the nitrates derogation could cost the Irish economy €45bn, devastating rural communities, and forcing up to one in eight dairy farming families to quit the industry.
