The Municipal Noise Mitigation Plan is legally established as a fundamental tool for managing and resolving noise pollution issues within a territory. This plan follows the primary municipal requirement: the Noise Zoning Plan. The Noise Mitigation Plan must be coordinated with all other urban planning tools and must incorporate the content of noise containment and reduction plans for transport infrastructure. As of 2023, this planning instrument remains scarcely implemented at the national level: only 66 out of 5,097 municipalities with an approved Noise Zoning Plan have also adopted a Noise Mitigation Plan, maintaining a percentage slightly above 1% over the years.

The management of noise pollution generated by airport infrastructures is carried out through the implementation of obligations set by current regulations. These include the approval of the acoustic characterization of the airport surroundings, a key territorial planning measure that regulates land use compatible with noise levels produced by the airport. Additionally, noise mitigation procedures are applied to minimize aircraft noise impact, along with the implementation and management of an airport noise monitoring system. To date, these obligations remain unfulfilled in many airports across the country. As of 2024, the acoustic characterization of the airport surroundings has been approved in 24 out of 42 airports handling national and international air traffic, 39 of which have been identified by ENAC as "airports of national interest", , marking a fundamental and priority step in the management of airport noise pollution.

The Noise Zoning Plan is the primary municipal planning tool for managing noise pollution. This plan involves dividing the municipal territory into acoustically homogeneous areas, each assigned specific noise limits. Its goal is to provide an essential tool for urban development planning and territorial protection from noise pollution.

As of 2023, the Noise Zoning Plan has been approved in 64% of municipalities nationwide. However, significant regional disparities persist in the application of this planning instrument.

The monitoring of hydrogeological risk mitigation projects funded from 1999 to December 31, 2023, by various administrations across the national territory is carried out by ISPRA through the ReNDiS platform (the Italian Repository of Hydogeological Mitigation measures). A total of 25,539 projects are recorded in ReNDiS, with a total funding amount of €19,207 million. Of these, the projects under the jurisdiction of the Ministry of the Environment and Energy Security (MASE) account for just over 26% (6,750) of the total, corresponding to approximately 41% (€7,819 million) of the total resources allocated by the other public funding administrations listed in ReNDiS. These include the Ministry of the Interior, the Civil Protection Department, the Casa Italia Department of the Presidency of the Council of Ministers, the Ministry of Agriculture, Food Sovereignty and Forests (MASAF) and the Calabria Region.

Specifically, projects under the jurisdiction of the Ministry of the Interior, the Civil Protection Department, the Casa Italia Department, MASAF and the Calabria Region represent over 73.5% (18,789) of the total number of projects, with funding exceeding 59% (€19,207 million).

Regarding the implementation status of all funded projects, 8,813 (approximately 34%) have been completed, 12% (2,951 projects) are under execution, 19% (4,836 projects) are in the design phase, while nearly 34% (8,703 projects) have yet to be started or have no reported data. The indicator also provides data on the regional distribution of projects and their classification based on the type of hydrogeological failure. Additionally, it presents data on funding requests submitted by Regions/Autonomous Provinces to MASE and the Casa Italia Department for the implementation of new hydrogeological risk mitigation projects, totaling 1,542 requests for a total project funding amount of approximately €4,440 million.

The indicator provides an overview of current regional planning activities relating to seven types of plans and the status of the associated Strategic Environmental Assessment (SEA) processes.
As of 31 December 2023, 129 plans out of 147 planned have been completed, achieving 88% coverage. In the same period, the total number of complete and in-force plans with SEA amounts to 103, representing 70% of all planned complete plans (147) and 80% of currently completed ones (129).

The indicator, referring to the 25 National Parks established as of 08/31/2023, represents the implementation status of Park Plans under Article 12 of Law 394/1991 within the complex process of drafting - adoption - approval by the competent authorities. Compared to 2020, the number of active plans has increased by one unit (Pollino National Park), reaching a total of 12. However, a general delay persists, particularly regarding plans pending approval. Considering the legal timeframe for the entry into force of a Park Plan, all National Parks (NPs) should have had an active plan by now. Instead, an average delay of 21 years in the approval process has been recorded.

This indicator focuses on the evolution of seismic classification and seismic regulations in Italy, with particular reference to seismic microzonation (MS). Regarding seismic classification, although it has not been the regulatory reference for seismic design since 2006—where reference is now made directly to the Technical Standards for Construction (Ministerial Decree of January 17, 2018)—it continues to serve as a reference for technical and administrative controls. The latest update provided by the Civil Protection Department, as of April 2021, classifies the territory into four main classes and sixteen subclasses, based on proposals from each region for its municipalities.

Regarding regulations governing seismic microzonation studies, the Civil Protection Department, in collaboration with the Conference of Regions and Autonomous Provinces, defined general guidelines and criteria in 2008. In subsequent years, some regions issued specific technical regulations adapting the general guidelines to their territories based on their particular vulnerabilities, concerning seismic amplification issues and, in some cases, surface fault rupture hazards. The seismic sequence that affected Central Italy starting on August 24, 2016, spurred the implementation of Level III seismic microzonation studies in all 140 affected municipalities. These studies were validated by a working group established by the Special Commissioner for Reconstruction in Central Italy. Various in-depth studies on active and capable faults within the Level III microzonation framework are ongoing and are expected to be completed by the end of 2021.
