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.

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.

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.

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.

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 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).

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.

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).

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 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 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.

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 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 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).

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.

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 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 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 allows for the assessment of emissions of major 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 vehicle-installed technologies. From 1990 to 2022, road emissions of non-methane volatile organic compounds (NMVOCs) decreased by 88.2%, nitrogen oxides (NOx) emissions by 74.8%, and fine particulate matter (PM) emissions by 75.0%. Sulfur oxides (SOx) emissions, now nearly absent from road transport, remain significant in maritime transport. The 2020 estimates reflect the effects of the pandemic, while 2021 and 2022 show a gradual recovery. Pollutant emissions into the atmosphere are monitored at the national level to verify compliance with reduction commitments imposed by European legislation, aiming to achieve air quality levels that do not cause significant negative impacts or risks to human health and the environment.

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 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 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 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 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 includes the emission allowances generated by installations covered by the EU Emissions Trading System (EU ETS), established under Directive 2003/87/EC, and the greenhouse gas emissions from all sectors not included in the ETS scope—namely small- and medium-scale industry, transport, residential and commercial buildings, agriculture, and waste. These are regulated under Decision No. 406/2009/EC (Effort Sharing Decision, ESD) up to 2020, and by the Effort Sharing Regulation (EU) 2018/842 (ESR) from 2021 onward. While non-ETS sector emissions in 2020 remained below the target threshold of 37 MtCO₂eq, in 2022 they exceeded the allowable limit by 5.5 MtCO₂eq, indicating a deviation from the reduction trajectory required to meet ESR targets.

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.

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).
