In 2021, the level of expenditure in the Italian economy for environmental protection amounted to 46.6 billion euros, equivalent to 2.6% of Gross Domestic Product (GDP). This ratio is the highest recorded since 2016, although it remained substantially stable between 2016 and 2021. Expenditure on environmental protection mainly concerns waste management and wastewater management. Other environmental protection purposes include, in order of importance, soil protection and remediation, groundwater and surface water protection; biodiversity and landscape protection; protection from radiation, research and development, other activities; air and climate protection; noise and vibration reduction (excluding workplace environmental protection).

The indicator analyzes the distribution of large and small dams in relation to the seismic classification of the national territory (Map of seismic zones OPCM March 20, 2003, n. 3274 and subsequent integrations), the Landslide Index of the IFFI Project (Italian Landslide Inventory), and the distribution of landslide-prone areas. For the year 2024, the indicator shows that the water surface of artificial and heavily modified natural lakes (the water perimeter for large and small dams) in areas with a null Landslide Index (IF) constitutes 71.6%, while only 1.8% falls in areas with a higher IF (IF>30). In terms of seismic activity, 7.4% of large dams and 2.2% of small dams are are located in the most dangerous area (seismic zone 1), while 20.6% and 11.9%, respectively, are in the least dangerous area (seismic zone 4). Due to incomplete data on the distribution of small reservoirs at the national level, the result is considered partial.

Territorial fragmentation is the process that leads to a progressive reduction in the area of natural and semi-natural environments and an increase in their isolation. This process, which transforms large land patches into smaller and more isolated parts, is primarily driven by urban expansion phenomena, which can take more or less sustainable forms, and the development of infrastructure networks aimed at improving connections between urbanized areas through linear works. In 2023, 42.34% of the national territory was classified as highly and very highly fragmented. The regions with the largest areas of very high fragmentation are Veneto (39.98%), Lombardia (33.57%), Emilia-Romagna (25.87%), and Campania (25.69%). This data confirms the strong correlation between fragmentation and urbanization density.

The analysis of the contribution of different primary energy sources to gross inland energy consumption shows that the dominant role of petroleum products is declining, while natural gas (37.9% of the total in 2022) and renewable sources (19.0% of the total in 2022) are increasing. Greater diversification and the growing role of renewables have a positive impact on Italy’s energy self-sufficiency level, which remains among the lowest in industrialized countries.

The indicator provides information about the landslide number and distribution in Italy. The recorded landslides exceed 635,000 (reference period 1116-2024) and affect an area of 25,004 km², accounting for 8.3% of the national territory.

The indicator provides information about the major landslide events caused fatalities, injuries, evacuations, damage to buildings, cultural heritage, and primary linear communication infrastructure or service networks in the national territory in the past year. The major landslide events occurred in 2023 were 192, with 11 deaths, 24 injuries, and damage mainly to the road network and buildings.

Internal Material Consumption (IMC) measures the apparent consumption of material resources within an economy. It is the main indicator derived from material flow accounts, used to assess a country's resource Productivity as part of policies on natural resource use. In 2023, Italy's Internal Material Consumption amounted to 498.4 million tonnes (-2.7% compared to the previous year), and Resource Productivity stood at 3.59 EUR/kg (+3.7% compared to the previous year).

During the 2007-2022 period, the majority of the assessed fish stocks are in a state of overexploitation: the fishing-induced mortality is higher than that necessary for a sustainable exploitation of the resources in the long term under average environmental conditions.

In the 2020-2022 triennium, the lowest values in the historical series were recorded, with approximately 60% of stocks classified as overexploited, indicating a relative improvement.

This indicator, based on internationally validated analytical stock assessments, reflects the overall trend in the exploitation status of commercially fished stocks, highlighting the condition of harvested resources. The indicator is also associated with the percentage coverage of landed fish stocks for which stock assessments are available. The analysis is conducted at both the national and subregional levels, following the geographic division defined by the Marine Strategy Framework Directive.

The indicator measures passenger transport demand (according to different modes) and compares its trend with that of economic growth and population. Transport demand is increasingly met by individual road transport (passenger cars and motorcycles), which, due to its growth and modal share (approximately 81% in 2023), remains dominant compared to other transport modes.

Italy hosts a remarkable floristic heritage, both in terms of species and subspecies richness (2,815 lichens, 1,209 bryophytes, and 8,241 native vascular entities) and biogeographical value. Of the 8,241 Italian vascular plant,1,702 species (equal to 20.65%) are endemic, meaning they exist exclusively in the country. Among these, 1,128 species are regionally endemic, with their range restricted to a single Italian region (data updated to April 2024).

The indicator also highlights the IUCN risk status of 2,430 vascular plant entities (representing 29.5% of Italy’s vascular flora), identifying the main threats affecting them. Unfortunately, the overall conservation status cannot be considered satisfactory: 2.2% (54 species) of the 2,430 evaluated entities are extinct or likely extinct; 24.3% (590 species) are at risk of extinction.

Human-induced pressures related to land-use changes represent a major driver of plant species extinction risk. The Red List of vascular flora identifies the most critical pressures affecting species: Modification of natural systems (39% of the 2,430 assessed taxa are subject to this pressure);

Agricultural development (27%); Residential development (27%); Direct human disturbance in natural environments (20%).

In 2020, the share of energy from renewable sources in Italy reached 20.4% of gross final energy consumption, exceeding the national target of 17% set for 2020. In 2021, the share decreased to 18.9%, and in 2022 it slightly rose to 19.1%, recording an increase of 0.2 percentage points compared to the previous year.

The indicator provides an overview of the current presence of alien animal and plant species in Italy through quantitative data, showing the temporal trends of introduction in Italy over the last century, the average annual introduction rate (average number of new alien species introduced each year), the  pathways (according to CBD categories), and the distribution of invasive alien species of Union concern. The number of alien species in Italy is progressively and constantly increasing. Based on currently available data, nearly 3,800 exotic species have been introduced into our country, of which 3,659 are currently present in the territory. The average number of species introduced per year has increased exponentially over time, increasing from 6 species/year in the 1970s to 16 species/year in the last decade,reaching nearly 30 species/year in the current decade. The cumulative number of species introduced in Italy since 1900 also confirms this exponential trend, with an increase of over 500% in 120 years.

Comparison within the European Union highlights that Italy's primary and final energy intensity remains below the European average. This is largely due to historical lack of domestic primary energy sources, —which has fostered energy-saving behaviours, efficient infrastructure, and a relatively low energy-intensive production structure—as well as a high level of energy taxation (which has raised end-user energy prices above those in other countries), lower per capita income, and a relatively mild climate. Based on a ranking of countries by increasing primary energy intensity, Italy ranks 7th among European nations.

The indicator evaluates the pressures on the environment and the efficiency of resources used by the economy to generate wealth, as well as its progress toward achieving a circular economy. In 2022, the ratio of national waste production to gross domestic product (GDP) was slightly above the European average (66 kg/1,000€ vs. 60 kg/1,000€). Overall, the economic system still appears unable to limit waste production in relation to the wealth produced. 

The indicator refers to carbon stock, i.e., the amount of carbon stored in Italy across the different forest carbon pools, and to the variation in carbon stock (carbon sink), which accounts for both the carbon sequestered and the emissions released due to wildfires, harvesting, and natural mortality within national forest ecosystems.

Carbon stock and carbon sink are effective indicators for assessing the condition of a country’s forest resources, as they are influenced by forest productivity and, negatively, by both natural and anthropogenic disturbances (such as fires, logging, pests and pathogens, natural mortality, etc.).

Carbon stocks in Italian forests are increasing, indicating a net positive balance between greenhouse gas (GHG) emissions and removals (carbon sink). This trend is partially driven by conservation and forest protection policies and, on the other hand, by a decrease in harvested timber volumes due to complex economic and social factors.

Emissions from forest fires remain a significant concern. The trend of the national carbon sink over the period 1990–2022 has been heavily affected by a reduction in GHG removals associated with areas burned annually. The impact of biomass loss from large-scale wildfires in 1990, 1993, 2007, and 2017 is particularly evident in the carbon sink trend.

This highlights the critical role of wildfires in shaping the contribution of national forests to the global carbon cycle.

The indicator represents the historical series of national greenhouse gas emissions from 1990 to 2022, broken down by sector. The data analysis shows a significant reduction in emissions in 2022 compared to 1990 (-21%), which can be explained by the economic recession that has slowed consumption in recent years, as well as by an increased use of renewable energy, leading to a reduction in CO2 emissions from the energy sector (-20% compared to 1990).

Statistical information on environmental taxes can be broken down by tax category, paying units, environmental activity class, and revenue destination. In Italy, environmental tax revenues amounted to €41.5 billion in 2022 (a decrease of 24.4% compared to the previous year). In 2022, environmental taxes accounted for approximately 5% of the total tax and social contribution revenues and about 2% of Gross Domestic Product (GDP).

The European Commission has adopted the European Biodiversity Strategy for 2030 (SEB 2030, COM(2020) 380 final), which sets the objective for Member States to protect at least 30% of their national territory and 30% of their seas, with at least one-third of these areas being strictly protected. These objectives are also incorporated into the National Biodiversity Strategy for 2030 (SNB 2030).

The indicator integrates spatial data from the main biodiversity protection systems existing in Italy (protected areas and the Natura 2000 Network), calculating the current protected surface both on land and at sea. It evaluates the variation from 1991 to 2023 and highlights the gap between the percentage of protected land and marine areas and the 30% target set by SEB 2030. The data used to calculate the extent of the protected area come from CDDA and the Natura 2000 database. Other Effective Area-based Conservation Measures (OECM) are not included, as the types of areas that may fall within this category have not yet been defined.

As of today, the total national coverage of protected areas, after accounting for overlaps between protected areas and Natura 2000 sites, is approximately 4,068,476 hectares at sea, equivalent to 11.62% of Italian territorial waters and the Ecological Protection Zone (ZPE), and about 6,532,341 hectares on land, covering 21.68% of the national territory. The extent of overlapping areas, i.e., those falling within both a protected area and a Natura 2000 site, has increased over time, reaching 862,631 hectares at sea and 2,447,046 hectares on land in 2023. The trends indicate that the percentage of protected national surface has stabilized since 2006 for marine areas and since 2011 for land areas. To meet the 30% target set by SEB 2030, an additional 18% of marine areas (approximately 6,600,000 hectares) and 8% of land areas (approximately 2,500,000 hectares) still need to be protected.

The circular material use rate measures the share of material resources reused by an economy. In the period 2004–2022, Italy's circular material use rate increased from 5.8% to 18.7%.
 

The number of areas and the extent of protected marine surface have steadily increased over time. Currently, Italy has 39 Marine Protected Areas (MPAs), established in 10 Italian regions; of these, 29 are Marine Protected Areas (AMPs). Sicily and Sardinia are the regions with the highest number of marine protected areas, both in terms of quantity and protected marine surface.

Between 2012 and 2019, the national surface area of MPAs increased by 1.9%, thanks to the establishment in 2018 of two Marine Protected Areas: Capo Testa - Punta Falcone in Sardinia and Capo Milazzo in Sicily.

The indicator provides the percentage of groundwater monitoring stations divided into quality classes based on the average nitrate concentration recorded over a four-year monitoring period (2016–2019). Specifically:

• 68.1% of stations show an average nitrate concentration below 25 mg/L,
• Only 12.6% of monitored points recorded an average concentration equal to or above 50 mg/L.

Additionally, an analysis comparing the trend over the last four years (2016–2019) to the previous four years (2012–2015) reveals predominantly stable nitrate concentrations, a decrease in average concentration at 37.9% of common stations between the two periods, and an increase at only 22.7% of the same stations.

In Italy, as of today, 843 terrestrial protected areas (including those with a marine component) have been established, covering a total protected surface of over 3 million hectares, which corresponds to approximately 10.5% of the national terrestrial area. Analyzing the historical series (1922-2019), it is possible to observe, especially from the mid-1970s onward, a positive trend in terms of both the number and surface area of terrestrial protected natural areas. However, since 2008-2009, there has been a certain stabilization in the growth trends.
