The European Commission has introduced a single EU-wide rulebook for large pig and poultry farms under the Industrial and Livestock Rearing Emissions Directive. Known as UCOL, it sets common minimum environmental standards for ammonia emissions and nitrogen and phosphorus excretion, while giving farmers flexibility to choose their own techniques. The rules will apply at farm level between 2030 and 2032 depending on farm size, and they cover roughly 30% of the EU's pig and poultry farms. For farmers, the main changes are operational rather than structural. Better manure handling, feeding strategies, and housing improvements are prioritized because they are seen as cost-effective ways to cut pollution. Member states can also validate alternative techniques with equivalent environmental performance, which leaves room for innovation. The practical test will be how these standards are enforced and whether the flexibility leads to real emission cuts or just variations in reporting.
