The Italian National Environmental Protection Agency Network (SNPA) has published updated guidelines titled "Emissioni Odorigene: Elementi di Riferimento e Approcci Metodologici per il Monitoraggio" (Odour Emissions: Reference Elements and Methodological Approaches for Monitoring). This technical document, approved in January 2025, replaces the 2018 framework and introduces cutting-edge solutions to address one of Italy's most persistent environmental challenges: odour pollution.
Developed by specialists from 20+ regional environmental agencies (ARPA) and ISPRA, the guidelines reflect Italy's most comprehensive odour management strategy to date. Because this guideline is written mainly by regulators, it has an extensive chapter on the diferent regulations related to odour management nationwide and also at a regional and a local scale. There you will see Italy's fragmented regulatory landscape, with regions adopting different approaches to odour management ranging from composting regulations (Lombardy) to integrated prevention measures (Basilicata). The SNPA 2025 guidelines aim to harmonize these framework.
