The European Commission's estimation from 2016 that around 18% of pig farms and 15% of poultry farms would fall under the requirements of the Industrial Emissions Directive (IED) has proven to be significantly off. The latest data from 2023 reveals a stark contrast, with over 60% of pig farms and 58% of poultry companies now falling under the directive's scope. In response to this discrepancy, the European Commission has decided to revise the proposal, after which it will be sent for review to the Member States and the European Parliament.
