What’s Required

Legislative Decree 46/2014 transposes the EU Industrial Emissions Directive (IED) into Italian law. It regulates emissions to air, water, and soil from large industrial installations and integrates pollution prevention through Best Available Techniques (BAT).

Operators of in-scope installations must:

  • Obtain and maintain a valid Integrated Environmental Authorisation (AIA).

  • Apply BAT conclusions and comply with emission limit values.

  • Monitor and report emissions according to permit conditions.

  • Update installations when BAT conclusions are revised.

Important Deadlines

  • Continuous compliance once AIA is granted.

  • BAT-related permit updates are typically required within 4 years of new BAT conclusions.

Current Status

Fully in force and actively enforced. AIA compliance is a key focus of inspections, especially for energy, chemicals, waste treatment, and heavy industry.

Penalties for Non-Compliance

  • Administrative fines for permit breaches.

  • Suspension or revocation of AIA.

  • Criminal liability in cases of serious pollution or environmental damage.

Examples of Known Violations

  • Operating without an updated BAT implementation.

  • Exceeding emission limit values.

  • Failure to submit monitoring data.
