EEA – Set of Indicators

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).

The indicator consists of the share of greenhouse gas emissions generated by installations covered under the EU Emissions Trading System (EU ETS), established by Directive 2003/87/EC, as well as emissions from all sectors not included in the ETS—namely small- and medium-scale industry, transport, residential and commercial buildings, agriculture, and waste. These non-ETS emissions were regulated under the Effort Sharing Decision (Decision No. 406/2009/EC) up to 2020 and, from 2021 onward, under the Effort Sharing Regulation (Regulation (EU) 2018/842).In 2020, emissions from the non-ETS sectors were below the national annual target of 37 MtCO₂eq. However, from 2021 onwards, emissions have not aligned with the annual reduction targets set under the Effort Sharing Regulation.

The indicator represents the historical series of national heavy metal emissions from 1990 to 2022, by source sector. Since 1990, a reduction in emissions has been recorded for all metals. In particular, emissions of cadmium, mercury, and lead are in line with the internationally set targets under the Aarhus Protocol, having decreased by -63%, -64%, and -95%, respectively, compared to 1990 levels.

The indicator represents the trend of national particulate matter (PM10) emissions by source sector from 1990 to 2022, showing a significant overall reduction over the years (-40.5%). The road transport sector, which contributes 10% to total emissions in 2022, shows a reduction of 65.6% over the entire period. Emissions from non-industrial combustion, on the other hand, have increased by approximately 37.6% during the same period, becoming the most significant sector in 2022, accounting for 45.3% of total emissions.

The Natura 2000 Network in Italy consists of 2,646 sites, covering a total area, net of overlaps, of 5,845,078 hectares on land, equivalent to 19.4% of the national territory, and 2,301,047 hectares at sea, corresponding to 6.4% of territorial waters (data updated to December 2023). A total of 643 Special Protection Areas (SPAs) and 2,364 Sites of Community Importance-Special Areas of Conservation (SCI-SACs) have been designated (of which 361 are SCI-SACs coinciding with SPAs). In December 2022, the sites numbered 2,639, with an increase of 7 units in the past year and an expansion of 163 hectares on land and 229,358 hectares at sea. The coverage percentages of the Natura 2000 Network vary across Italian regions and autonomous provinces, ranging from 12% to 36% on land and from less than 1% to 30% at sea.

The national coverage of the Network is significant in relation to the targets of the EU Biodiversity Strategy for 2030 (SEB2030), which calls for expanding protected areas in the EU to reach at least 30% of terrestrial and 30% of marine areas. The SEB2030 target includes all areas subject to protection measures, such as Natura 2000 sites, National and Regional Parks, and other protected areas. At the regional level, Abruzzo and Valle d’Aosta meet the SEB2030 target, with Natura 2000 sites covering 36% and 30% of their territories, respectively. Other regions approaching the target include the Autonomous Province of Trento (28%), Molise (27%), Campania (27%), and Liguria (26%). The protection percentages of Natura 2000 marine sites are lower, with only Puglia (30%) and Tuscany (27%) having protection levels close to the target.

The phenomenon of forest fires analyzed based on data collected from 1970 to 2023 by the State Forestry Corps, now CUFA (Carabinieri Forestry, Environmental and Agri-food Unit Command), shows a fluctuating trend, with peak years (1993, 2007, 2017, 2021) alternating with years of decline (2013, 2014, 2018). The presence of fires within Protected Areas is high, with exceptionally large burned areas recorded in certain years, such as 2021 and 2022, when 26,507 hectares and 11,101 hectares were affected by fire, respectively.

The incidence of intentional fires is very high, accounting for approximately half of all recorded events and exceeding 60% in some years (2012, 2014, 2015, 2016, 2020).

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 indicator illustrates the national emission trends of tropospheric ozone precursors—namely nitrogen oxides (NOx) and non-methane volatile organic compounds (NMVOCs)—disaggregated by emission source sector. A significant overall decline is observed between 1990 and 2022, amounting to -71% for NOx and -58% for NMVOCs, primarily driven by substantial reductions in emissions from the transport sector.

The indicator describes the trend of national emissions of acidifying substances SOx, NOx, and NH3, both at the total and sectoral levels, highlighting the decreasing trend from 1990 to 2022 (-72.3%). With reference to Directive 2016/2284 of the European Parliament and of the Council, concerning the reduction of national emissions of certain atmospheric pollutants, which defines the national emission reduction commitments relative to 2005, applicable from 2020 to 2029 and from 2030 onwards, sulfur oxides and ammonia have already reached the reduction target for 2020 by 2009; whereas nitrogen oxides reached it in 2014.

The indicator describes the status of the 42 Contaminated Sites of National Interest (SIN), which together cover 148,594 hectares of land surface (0.49% of the Italian territory) and 77,136 hectares of marine areas. This issue affects all Italian regions, except Molise. As of 30 June 2024, for 65% of the total area of the 36 SINs under consideration, information is available on the progress of the procedures: characterization has been completed for 59% of the soils and 55% of the groundwater, while remediation/safety measures have been approved by ministerial decree for 13% of the soil area and 17% of the groundwater. Procedures have been completed for 17% of the soils and 6% of the groundwater. The information provided by the indicator outlines a representative picture of environmental conditions and societal responses in relation to regulatory and sustainability objectives.

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.

In 2023, the total amount of municipal waste disposed of in landfills amounted to approximately 4.6 million tonnes, with 112 landfill facilities in operation nationwide. Compared to 2022, this represents a 10.8% reduction in the total quantity of municipal waste landfilled (equivalent to -559,000 tonnes) and a 4.3% decrease in the number of operational sites (-5 facilities).

National municipal waste (MW) generation in 2023 amounts to approximately 29.3 million tonnes, marking a 0.7% increase (approximately +218,000 tonnes) compared to 2022.

The indicator describes the trend of mean temperature in Italy.
The increase in mean temperature recorded in Italy over the last thirty years has often exceeded the global average over land. In 2023, the mean temperature anomaly in Italy, relative to the 1991–2020 climatological baseline, was +1.14 °C—higher than the global land surface anomaly of +0.86 °C. In Italy, 2023 ranked as the second warmest year in the entire annual time series starting from 1961. Since 2000, temperature anomalies relative to the 1991–2020 baseline have consistently been positive, except for four years (2004, 2005, 2010, and 2013).

The indicator is based on atmospheric PM10 concentration data measured in 2023 at monitoring stations distributed across the national territory, collected and archived by ISPRA in the InfoAria database, in accordance with Directive 2008/50/EC (and its national transposition, Legislative Decree 155/2010) and Commission Implementing Decision 2011/850/EU. A total of 573 monitoring stations reported PM10 data. Of these, 541 provided time series with sufficient temporal coverage for validation against reference thresholds. No exceedances of the annual limit value were recorded, whereas the daily limit value was exceeded at 63 stations (equivalent to 12% of cases). Furthermore, the vast majority of monitoring stations reported exceedances of both the WHO annual reference level (91% of cases) and the daily reference level (84% of cases).

The indicator is based on atmospheric concentration data of benzo(a)pyrene measured in 2023 at monitoring stations distributed across the national territory, collected and archived by ISPRA in the InfoAria database, in accordance with Directive 2008/50/EC (and its national transposition, Legislative Decree 155/2010) and Commission Implementing Decision 2011/850/EU. A total of 164 monitoring stations measured and reported B(a)P data. Among these, 159 provided time series with sufficient temporal coverage for the verification of reference values. Exceedances of the target value were recorded at 17 stations, corresponding to 10.7% of the cases.

The indicator is based on nitrogen dioxide (NO₂) concentration data measured in 2023 at monitoring stations distributed across the national territory, collected and archived by ISPRA in the InfoAria database, in accordance with Directive 2008/50/EC (and its national transposition, Legislative Decree 155/2010) and Commission Implementing Decision 2011/850/EU. A total of 630 monitoring stations measured and reported NO₂ data. Of these, 600 provided data series with sufficient temporal coverage to verify compliance with reference values.

The hourly limit value was respected at all stations: no exceedance of 200 µg/m³ (hourly average) for more than 18 occasions was recorded. The WHO reference value, which does not permit any exceedances of 200 µg/m³, was exceeded at 8 stations (1.3% of those with sufficient data coverage). The annual limit value, set at 40 µg/m³ (annual mean), was exceeded at 13 stations (2.2%). The WHO guideline value for long-term human health protection, set at 10 µg/m³ as an annual mean, was exceeded at 450 stations (75.0%).

The indicator is based on atmospheric ozone (O₃) concentration data measured in 2023 at monitoring stations distributed across the national territory, collected and archived by ISPRA in the InfoAria database, in accordance with Directive 2008/50/EC (and its national transposition, Legislative Decree 155/2010) and Commission Implementing Decision 2011/850/EU. A total of 348 monitoring stations measured and reported ozone data. Of these, 326 provided data series with sufficient temporal coverage to assess compliance with threshold values and the long-term objective (LTO) for the protection of human health.

Suburban, rural, and background rural stations meeting the minimum data coverage required for the calculation of the long-term objective for vegetation protection (AOT40v) numbered 146. The LTO for human health was exceeded at 88.1% of stations. In 43.9% of the stations, this LTO was exceeded for more than 25 days.

The information threshold for health protection was exceeded at 34% of stations, while the alert threshold was exceeded at only 2 stations. The WHO reference level—set at 100 µg/m³ as the 99th percentile of daily maximum 8-hour mean concentrations—was exceeded at 313 stations (96% of those with sufficient data coverage). The long-term objective for vegetation protection (AOT40v) was exceeded at 93.2% of the stations.

The indicator is based on atmospheric PM2.5 concentration data measured in 2023 at monitoring stations distributed across the national territory, collected and archived by ISPRA in the InfoAria database, in accordance with Directive 2008/50/EC (and its national transposition, Legislative Decree 155/2010, as amended) and Commission Implementing Decision 2011/850/EU.

A total of 334 monitoring stations measured and reported PM2.5 data. Of these, 310 provided data series with sufficient temporal coverage to assess compliance with reference values. The annual limit value for PM2.5 (25 µg/m³) was met at all stations except one, corresponding to 0.3% of cases. However, the majority of monitoring stations (99.7%) exceeded the updated WHO annual reference value of 5 µg/m³ (previously set at 10 µg/m³).

Estimates of annual population-weighted exposure (PWE) to nitrogen dioxide (NO₂), aggregated at municipal level, were produced using an integrated approach combining measurements and statistical modelling. The resulting data, covering the period 2016–2023, allow for comparison of PWE across all municipalities and provide a comprehensive national overview of average exposure levels.

In 2023, 77% of the population was exposed to concentrations above the WHO air quality guideline (10 µg/m³).
The national average PWE was 11 µg/m³ (minimum–maximum range: 3–37 µg/m³).
Over the period 2016–2023, there was an average 28% reduction in exposure levels, mainly attributable to a decline in road traffic emissions.

Estimates of annual population-weighted exposure (PWE) to PM10, aggregated at municipal level, were produced using an integrated approach combining measurements and statistical modelling. The resulting data, covering the period 2016–2023, allow for comparison of PWE across all municipalities and provide a comprehensive national overview of average exposure levels.
In 2023, 96% of the population was exposed to concentrations above the WHO air quality guideline (15 µg/m³).
In the period observed, no decreasing trend in exposure levels was detected. The national average in 2023 was 20 µg/m³ (minimum–maximum range: 6–35 µg/m³).

Estimates of annual population-weighted exposure (PWE) to PM2.5 aggregated at municipal level, were produced using an integrated approach combining measurements and statistical modelling. The resulting data, covering the period 2016–2023, allow for comparison of PWE across all municipalities and provide a comprehensive national overview of average exposure levels.
In 2023, 100% of the population was exposed to concentrations above the WHO air quality guideline (5 µg/m³).

The national average in 2023 was 12 µg/m³ (minimum–maximum range: 4–25 µg/m³).

Between 2016 and 2023, the national average decreased from 15 µg/m³ in 2016 to 12 µg/m³ in 2023, corresponding to a reduction of 20%.

n 2023, organic farming in Italy covered 2,456,020 hectares, involving approximately 94,400 organic operators. Organic agriculture accounted for 7.4% of all farms and 19.8% of the utilised agricultural area (UAA), according to the 2021 ISTAT Census, falling 5.2 percentage points short of the 25% UAA target for organic farming. 

Over the past 33 years, the trend has been upward in both the number of operators and cultivated area, countering the long-standing decline in utilised agricultural area in Italy.

 At the European level, Italy ranks among the most virtuous Member States.

The indicator describes greenhouse gas (GHG) emissions (CH₄, N₂O, CO₂) released into the atmosphere by the agricultural sector, mainly due to livestock management and fertilizer use. It allows for the assessment of the sector’s contribution to total national emissions and the achievement of emission reduction targets.

Since 1990, greenhouse gas emissions from the agricultural sector have shown a decreasing trend; however, further mitigation measures will be necessary to meet the targets established under the United Nations Framework Convention on Climate Change (UNFCCC), the Kyoto Protocol, and relevant European directives.

Specifically, Italy’s target for 2030 under the Effort Sharing Regulation (Regulation (EU) 2023/857) is a -43.7% reduction in total GHG emissions from agriculture, buildings, transport, waste, and industrial installations not covered by the EU Emissions Trading System (EU-ETS), compared to 2005 levels.

In 2022, GHG emissions from agriculture accounted for a relatively small share (11.2%) of total emissions from sectors covered by the Effort Sharing Regulation, while emissions from agriculture decreased by 12.2% compared to 2005.

The indicator measures the energy consumed by end users and the total energy consumed by the country. Since 1990, there has been a general upward trend in the energy available for final consumption, reaching a peak in 2005. This was followed by a reversal, with consumption declining to a minimum in 2014. From then until 2018, a recovery in final consumption was observed, followed by a decrease in 2019 and a sharp drop in 2020 due to the lockdown of economic activities aimed at containing the spread of the SARS-CoV-2 pandemic. Consumption then rebounded in 2021, before declining again in 2022. In 2022, the energy available for final consumption—calculated according to the methodology adopted by Eurostat—amounted to 112.0 Mtoe, a 6.9% decrease compared to 2021.

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 "chlorophyll" parameter is the only direct indicator of phytoplankton biomass available and has taken on the role of a metric for classifying ecological status according to the Biological Quality Element (BQE) – Phytoplankton in coastal waters (Ministerial Decree 260/2010). Chlorophyll is particularly sensitive to changes in trophic levels determined by nutrient (N and P) inputs from catchment basins flowing into the coastal area.
In 2020, high status was recorded in 71.4% of cases, good status in 12.3%, and sufficient status in 16.2%. A general improvement in status was observed in Campania and Marche, while Emilia-Romagna and Sardinia saw a worsening. Marche, Liguria, and Abruzzo maintained all stations at high status.

Descriptor 8 of the Marine Strategy Framework Directive 2008/56/EC (MSFD), in order to achieve good environmental status of marine waters through the gradual elimination of pollution, specifically requires the assessment of the presence of chemical contaminants and their effects in environmental matrices. During the 2021–2023 period, ISPRA conducted monitoring of the Adriatic Sea Subregion (MAD), Ionian Sea and Central Mediterranean Subregion (MIC), and Western Mediterranean Subregion (MWE). The data were processed and integrated with those provided by regional agencies and experimental zooprophylactic institutes.

This monitoring revealed that, although the data coverage for the study of contaminant concentrations varied across matrices and subregions, there was an overall improvement. This allowed for the assessment of GES (Good Environmental Status) for the sediment matrix in two MRUs and for the biota matrix in the Adriatic MRU.

The ecological status of surface waters reflects the quality of the structure and functioning of aquatic ecosystems. Directive 2000/60/EC (transposed in Italy with Legislative Decree 152/2006) mandates the achievement of "good" quality status for water bodies, which is determined by the assessment of both ecological and chemical status. The indicator provides an evaluation of the ecological status of surface water bodies—specifically inland waters—based on classification data from the WISE 2022 Reporting related to the 3rd Water Management Plan. At the national level, comparing the ecological quality status data between the 2nd and 3rd Management Plans shows a reduction in water bodies with unknown status, from 18% to 10%, though they are still present. In general, the ecological status has not significantly changed from the previous management cycle, except for the percentage of lakes in good status, which has increased from 17% to 35%.

The tide is a periodic phenomenon of rising and falling sea levels caused by the gravitational attraction exerted by the Moon, the Sun, and other celestial bodies on the Earth's water masses, and secondarily by meteorological disturbances. Data from the National Tide Gauge Network (ISPRA) were used to characterize the amplitude of the astronomical component of the tidal signal along Italian coasts. As well known, astronomical tides vary significantly across the different Italian seas, reaching their maximum range in the Northern Adriatic and Venice Lagoon, being strongly influenced by the basin's configuration.

The 12-month Standardized Precipitation Index (SPI) maps provide a nationwide and large-scale assessment of hydrological drought conditions, obtained using precipitation data collected and published by regional hydro-meteorological services and autonomous provinces and those of the suppressed National Hydrograph and Tire Service (SIMN, now merged into ISPRA) of the Department for National Technical Services. The 12-month aggregation timepiece chosen for the SPI assessment is the one that best describes the effects of drought (precipitation deficit) on the flow rate of rivers, recharging reservoirs and water availability in the aquifers.

In 2024, the 12-month SPI maps (SPI12) showed extreme and moderate drought conditions for the territories of central Italy and for the South and the major islands. The months from June to August 2024 were the most characterized by extreme drought conditions on the 12-month time scale (SPI12 –2.0), as a result of the precipitation deficit found in the second half of 2023 and then in 2024, particularly on southern Italy. The maximum extent reached by this condition was observed in June (16.1% of the Italian territory). From May 2024 until the end of the year, there was also an increase in areas characterized by severe or moderate drought on the 12-month time scale (–2.0 SPI12 –1.0). In this period, with the exception of October and December, the percentage of Italian territory subject to these conditions was always more than 20%, with a maximum in May (28.5%) and a minimum in September (21.6%).

The intensity and persistence of these conditions in 2024 had effects on the availability of water resources in different areas of Italy, resulting, consequently, in environmental and socio-economic impacts related to the use of water.

The indicator evaluates the demand for freight transport (also in relation to economic growth) and the evolution over time of modal split. The transport demand is increasingly met by road freight transport, which continues to dominate other transport modes in terms of growth and modal share (approximately 62% in 2023).

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.

The indicator allows for the assessment of emissions of the main air pollutants produced by the transport sector. In Italy, harmful emissions from road transport have significantly decreased in recent years, thanks to the introduction of catalytic converters, particulate filters, and other technologies installed in vehicles. From 1990 to 2023, road emissions of non-methane volatile organic compounds decreased by 87.6%, nitrogen oxide emissions by 71.3%, and fine particulate emissions by 69.9%. Sulfur oxide emissions, now almost absent in road transport, remain significant in maritime transport. Air pollutant emissions are monitored at the national level to verify compliance with reduction commitments set by the European Union, with the goal of achieving air quality levels that do not cause significant negative impacts or pose serious risks to human health and the environment.

This indicator tracks the share of road vehicles complying with the most recent emission standards during the 2005-2022 period. In 2022, passenger cars still showed a non-negligible proportion (13.7%) of Euro 0 gasoline vehicles, while for diesel cars this share was significantly lower at approximately 2.9%. More concerning is the commercial vehicle fleet situation - predominantly diesel-powered - where 11.2% of light commercial vehicles (vans) and 27.1% of heavy goods vehicles remain at Euro 0 standard.

The EPRTR (European Pollutant Release and Transfer Register) is the integrated register established by the EU based on Regulation (EC) No. 166/2006, aimed at making publicly available information on environmental impacts caused by industrial facilities falling under the criteria set out in the regulation.

This indicator represents total emissions into surface waters and pollutant transfers in wastewater from industrial facilities that reported such data to the national PRTR register. For the year 2020, 60 substances were reported as present in emissions into surface water bodies, while 49 substances were declared in pollutant transfers via wastewater conveyed through pipelines to external treatment facilities.

The PRTR activity groups that contribute the highest percentages of reported pollutant emissions into both wastewater and surface waters are generally those related to "Waste and Wastewater Management" and "Chemical Industry".

The EPRTR (European Pollutant Release and Transfer Register) is the integrated register developed by the EU under Regulation (EC) No 166/2006, with the aim of making publicly available information on environmental impacts from industrial facilities that meet the criteria established in the legislation. This indicator represents the total air emissions from industrial facilities that have reported such emissions to the national PRTR register. The air emissions declared for 2020 refer to 34 substances (non-zero values). Comparing 2020 data with 2007, it is observed that for 25 substances, total national atmospheric emissions have decreased (for 23 of these, reductions exceed 40%), while for 8 substances, overall emissions have increased (including: hydrogen cyanide +356% from 2007, hydrofluorocarbons +19%, and ammonia +109%).

The indicator allows for the assessment of surface and groundwater contamination by pesticide residues released into the environment. Monitoring pesticide presence in water is complex due to the number of substances involved and their diffuse use. Measured levels are compared with the concentration limits established by current regulations. The presented indicators provide an analysis of the evolution of contamination over the 2012–2021 decade, in terms of the frequency of pesticide detection in water, as well as the environmental risks arising from their use. Data from 2021 confirm a state of contamination already reported in previous years, with exceedances of legal limits particularly in surface waters (28.3% of monitoring points); in groundwater, 6.8% of points exceed regulatory limits.

In 2022, the sixth edition of the Catalogue of Environmentally Relevant Subsidies identified a total of 183 measures, resulting in €24.2 billion in Environmentally Harmful Subsidies (EHS) and €20.2 billion in Environmentally Beneficial Subsidies (EBS), representing a year-on-year increase of 15.1% and a decrease of 2.5%, respectively. Subsidies amounting to €13.8 billion were classified as having uncertain environmental impact, marking a 7.5% increase compared to 2021. Among the Environmentally Harmful Subsidies, those related to fossil fuels accounted for €17 billion in 2022 (compared to €13 billion in 2020 and €14.8 billion in 2021).

The indicator represents projections of national greenhouse gas emissions up to 2040, based on the current policies scenario as of 31/12/2022, including those implemented under the National Recovery and Resilience Plan (NRRP), as well as the additional policies and measures scenario defined in the Integrated National Energy and Climate Plan (INECP). The scenarios are calculated starting from the most recent consolidated historical data for 2022, and reflect the expected evolution of key macroeconomic drivers as reported to the European Commission. The projected reductions in total greenhouse gas emissions (including LULUCF) by 2030, compared to 1990 levels, are estimated at -38% under the current policies scenario and -49% under the additional measures scenario.

The indicator quantifies the extraction of natural resources - biomass, metallic minerals, non-metallic minerals, and fossil fuels - globally, due to the final consumption and investments of households, businesses, and public administrations in Italy. In 2023, Italy's material footprint amounted to 656.1 million tons, or 11.1 tons per capita.

The circular material use rate measures the share of material resources reused by an economy. In the period 2004–2023, Italy's circular material use rate increased from 5.8% to 20.8%.

Le informazioni statistiche relative alle imposte ambientali possono essere articolate secondo la categoria di imposta, le unità che le corrispondono, la classe di attività ambientale e la destinazione del gettito. In Italia, le imposte ambientali ammontano nel 2024 a 60,8 miliardi di euro (+11,6% rispetto all'anno precedente). Nel 2024, il gettito delle imposte ambientali corrisponde a circa il 6,1% del gettito totale delle imposte e contributi sociali (2023) e a circa il 3% del Prodotto interno lordo.

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).

During the period considered (2007-2022), the average exploitation rate of fish stocks (i.e., the mean ratio between current fishing mortality and the mortality associated with the Maximum Sustainable Yield; Fcurr/FMSY) exceeded the sustainability threshold. The indicator, estimated on internationally validated analytical stock assessments, highlights the overall trend in the exploitation rate of commercially fished stocks, providing insight into the quantitative trends in fishing pressure.

A peak in the average exploitation rate was observed in 2012 and 2013, with values exceeding 3, followed by a declining trend, reaching its lowest point in 2022 (average value of 1.12). The analysis is conducted at the National level and by Sub-Region, following the geographical scale defined by the Marine Strategy Framework Directive (MSFD; 2008/56/EC).

The indicator represents the trend of national emissions of particulate matter (PM2.5) by source sector from 1990 to 2022, highlighting a significant overall reduction over the years (-39%). The road transport sector, which contributes 9.3% of total emissions in 2022, shows a 75% decrease over the entire period. Emissions from non-industrial combustion, during the same period, increased by almost 38%, making it the most significant sector in 2022, accounting for 63.8% of total emissions.

The indicator illustrates the conservation status and trends of Italian species protected under Directive 92/43/EEC (Habitats Directive) and is based on the summary results of the 4th Italian report for the period 2013-2018, submitted to the European Commission in 2019. The report covers a total of 349 species (232 animal species and 117 plant species) of Community interest present in our territory and seas. In the 4th report, a total of 337 distribution maps and 619 reporting forms were produced (one for each species in every biogeographical region where it is present). The 2019 assessments show that over half of the terrestrial and inland water species, 54% of the flora, and 53% of the fauna, as well as 22% of the species evaluated in the marine context, have an unfavourable conservation status (inadequate or poor). A comparison between the two most recent reporting periods (2007-2012 and 2013-2018) reveals no improvements in the conservation status of the species. The only positive signal is the increase in knowledge, with a decrease in cases where the conservation status was unknown. The indicator highlights the urgent need for greater commitment to the conservation of species protected by the Habitats Directive, in relation to the target of the European Biodiversity Strategy to 2030, which sets out that at least 30% of species and habitats in unfavourable conservation status should improve their status by 2030 or show at least a trend of improvement.

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.

The indicator is useful for monitoring progress toward a circular economy, allowing for the identification of the quantities of materials reintroduced into the economy following waste treatment. Compared to the total amount of waste sent for recovery and disposal operations, more than three-quarters of the treated waste is recycled, placing Italy among the countries with the highest recycling rates.

The indicator measures the abundance and diversity of bird populations in Italy throughout the year, based on bird ringing data. This assessment helps define Italy’s role in the spatial-temporal distribution of European avifauna. Data from 2019-2020 confirm Italy’s crucial importance as a major migration corridor between Europe and Africa and contribute to identifying critical periods for bird species, which is essential for conservation and management purposes.

The Habitats Directive (92/43/EEC) is one of the main pillars of the European Union's nature conservation policy. This indicator is based on data provided by Italy for the periodic reporting required of Member States under Article 17 of the Directive. The report provides a general summary of the Italy’s Fourth Report, referring to data from monitoring activities conducted by regions and autonomous provinces during the 2013–2018 period. Specifically, it highlights the overall conservation status observed for terrestrial and inland water habitats across the national territory, as well asthe distribution of conservation status across the Italian biogeographical regions. Additionally, the report outlines the number of assessments to be conducted by individual regions and autonomous provinces for habitat monitoring, providing an estimate of the expected workload.

The trend compared to the previous reporting cycle is negative, showing a decrease in favorable assessments. Currently, only 8% of cases are classified as having a favorable conservation status, while 49% are deemed inadequate and 40% poor. This indicates a generally critical situation, further distancing Italy from achieving the objectives set by the Directive.

Eutrophication is a process caused by the enrichment of nutrients, particularly nitrogen and phosphorus compounds, which leads to an increase in primary production and algal biomass, resulting in the alteration of benthic communities and, in general, a decline in water quality. The input of nitrogen and phosphorus into the marine and coastal environment can originate from diffuse sources (river loads, major collectors of agricultural activity, and urban discharges) and point sources (discharges from wastewater treatment plants, industrial activities, and aquaculture operations). Objectives related to eutrophication control and management are set by the Water Framework Directive (WFD, Directive 2000/60/EC), the Marine Strategy Framework Directive (Descriptor 5, Directive 2008/56/EC), and the Nitrates Directive (Directive 91/676/EEC) and Urban Waste Water Treatment Directive (Directive 91/271/EEC), which are particularly focused on pressure management. The causes of eutrophication are primarily linked to nutrient inputs carried into the sea by rivers or coastal settlements, which cause serious negative impacts on the health of marine ecosystems and the sustainable use of goods and services. The main sources of nutrients are related to the agri-livestock and urban sectors.

Environmental assessments regarding eutrophication, in accordance with the requirements of Directive 2008/56/EC, have highlighted the achievement of Good Environmental Status. Therefore, the measures adopted so far under Directive 2000/60/EC, Directive 91/676/EEC, and Directive 91/271/EEC have proven effective in achieving environmental targets.

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.

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.

This indicator provides a national overview of the conservation status of 268 breeding bird species assessed in the reporting under Article 12 of the Birds Directive 2009/147/EC. The assessment includes species of community interest listed in Annexes I and II of the Directive, as well as those that justify the designation of Special Protection Areas (SPAs).

At the national level, the percentage of species with a favourable conservation status increased from 51% (reporting period 2007-2012) to 56% (reporting period 2013-2018). However, this increase was insufficient to meet the target set by the EU Biodiversity Strategy 2020 (76%).

The short-term population trends, which reflect processes occurring in the last decade, indicate that 46% of species are increasing or stable, while nearly 25% of species are in decline (the population trend of the other 33% remains unknown). Regarding short-term trends in distribution range, the proportion of declining species is lower, as only the most severe declines result in range contractions: 21% of species show a contraction, while the remaining 79% have stable or expanding ranges.
