Climate change

The efficiency indicator, calculated for the years from 1990 to 2020, represents carbon dioxide emissions per unit of value added in the manufacturing and construction sectors in Italy. The substantial reduction in emission intensity over the years (-48% between 1990 and 2020) indicates an improvement in the level of efficiency achieved by the Italian manufacturing and construction industry.

The indicator illustrates electricity consumption in the tourism sector, identified by the ATECO category "Accommodation and Food Service Activities". In 2023, this sector accounted for 4.2% of total electricity consumption in Italy. When considering only accommodation activities—such as hotels, campsites, and other short-term lodging facilities—this share drops to 1.5%. In 2023, within the "accommodation" subcategory, 83.8% of electricity consumption was attributable to "hotels and similar establishments".

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).

In 2023, Italy experienced one of the hottest years in the last 150 years, second only to 2022. The average and maximum temperatures reached new records with October recording temperatures more than 3°C higher than the 1991-2021 average, marking the highest value since 1961. During the summer, intense heatwaves affected the country, with record temperatures of 48.2°C recorded on July 24 in Jerzu and Lotzorai in Sardinia, and 41.2°C in Rome in early August. Drought continued to be a significant problem, with Northern and Central Italy experiencing severe drought conditions in the first four months of the year, which later eased. However, in the last three months of the year, Sicily and parts of Ionian Calabria suffered from extreme drought with a significant precipitation deficit.
Extreme weather events affected several regions, causing severe damage. In May, Emilia-Romagna was devastated by two exceptional rainfall events, leading to flooding, landslides, and 17 fatalities. On November 2, heavy thunderstorms in Tuscany caused flooding and 8 deaths, with exceptional rainfall recorded in the provinces of Pisa, Livorno, Pistoia, and Prato.
In summary, 2023 was characterized by record temperatures, persistent drought, and extreme weather events that had a significant impact on various italian regions.

The indicator provides an overview of the health status of common migratory passerine bird populations in Europe by assessing their resilience to climate change. Rising spring temperatures due to global warming trigger an earlier onset of vegetation growth which in turn leads to, an earlier peak in insect availability. If migratory birds do not adjust their arrival at breeding sites accordingly, they may struggle to find sufficient prey to feed their chicks. A failure to anticipate migration timing translates into lower resilience to climate change, ultimately threatening population survival.

This study examines the temporal variation in the arrival dates of migratory passerines at stopover sites used after crossing the Sahara and the Mediterranean Sea during their spring migration from Africa to European breeding grounds. Based on the analysis of migration timing for 10 bird species recorded at 26 ringing stations participating in ISPRA’s Piccole Isole Project over a 36-year period (1988–2023), the study found that 40% of the species exhibitmigration shifts that are too slow (advancing by only about one day every seven or more years) to effectively counteract the impacts of climate change. 

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.

Ocean warming is causing a geographical and depth shift in marine species more sensitive to temperature changes. In temperate zones, such as the Mediterranean, this phenomenon results in a northward expansion of warm-affinity species. Consequently, the composition of marine communities changes, affecting commercial fishery landings.

The mean temperature of the catch (MTC), which is the average inferred temperature preference of the exploited species weighted by their annual landings, is an index that has been used for evaluating the effect of sea warming on fisheries catches and marine ecosystems (Cheung et al., 2013).

Adriatic Sea (FAO Division 37.2.1): The mean temperature of the catch increased from 19.2°C (1987–1996 average) to 20.1°C (2012–2022 average), with a significant annual increase of 0.03°C.

Ionian Sea – Central Mediterranean (FAO Division 37.2.2): The mean temperature of the catch increased from 20.3°C (1987–1996 average) to 22.3°C (2012–2022 average), with a significant annual increase of 0.07°C.

Sardinian Sea – Western Mediterranean (FAO Division 37.1.3): The mean temperature of the catch increased from 20.5°C (1987–1996 average) to 22.5°C (2012–2022 average), with a significant annual increase of 0.07°C.

The indicator provides an estimate of the input and removal of nitrogen and phosphorus in coastal environments where aquaculture activities take place. Specifically, fish farming contributes to the release of these nutrients, while mussel farming facilitates their removal.

The balance between the nutrient input from farmed fish and the nutrient removal by bivalve shellfish allows for a regional-level assessment of the net quantitative contribution of aquaculture to trophic processes along the Italian coastline.

At the national level, in 2020, estimates of the nitrogen and phosphorus balance from intensive fish farming and mussel farming showed a reduction compared to 2019. This decrease was due to:

• A decline in nutrient input resulting from lower fish production

• A decrease in nutrient removal due to the reduction in mussel production

  At the regional level, in Veneto, Emilia-Romagna, Abruzzo, Molise, and Marche, the removal of nitrogen and phosphorus by mussels exceeded the input from farmed fish.

In 2022, 1.1 million tons of special waste were sent for incineration, of which approximately 699,000 tons (63% of the total) were non-hazardous and over 409,000 tons (37% of the total) were hazardous. The total number of plants that received special waste is 70, 27 of which are primarily authorized for the treatment of municipal waste. The majority of these plants are located in the North (43), with 7 in the Center and 20 in the South. In line with the distribution of the incineration plant fleet, the majority of special waste is treated in plants located in the North (83.9% of the total, over 929,000 tons), followed by the Southern regions with 13.8% (over 153,000 tons) and the Central regions with 2.3% (25,000 tons). 

The indicator measures the quantity of special waste treated in production plants across the country, used either partially or entirely as a substitute for traditional fuels. In 2022, more than 1.8 million tons of special waste were recovered in co-incineration plants. Compared to 2021, the quantities of energy recovered are substantially stable, showing a slight decrease of about 1,000 tons (-0.1%). The regional distribution shows that the majority of special waste, 75.4% of the total, is recovered in the Northern regions, followed by the Central regions with 12.8% and the Southern regions with 11.8%. 

White Certificates, also known as “Energy Efficiency Titles” (EET) were introduced by Ministerial Decree of 24 April 2001 to promote the implementation of energy efficiency measures in end-use sectors to meet national energy savings targets for obligated parties. TEE are tradable securities that certify energy savings achieved in energy end-use through the implementation of specific interventions to increase energy efficiency. Each certificate represents a saving equivalent to one tonne of oil equivalent (toe). The White Certificates (WC) mechanism has been gradually modified over the years, in line with legislative developments. In the 2006-2023 period, additional primary energy savings equal to approximately 29.3 Mtoe were certified and 58.5 million energy efficiency certificates were recognised.
