Italy's Neighbours: Polluters Or Not?

Italy is taking steps to address climate change, but it is still facing significant environmental challenges. The country is vulnerable to the impacts of the climate crisis, including rising temperatures, more frequent and severe heat waves, and extreme weather events. While Italy has made progress in addressing air pollution, particularly in reducing smog levels since the 1970s and 1980s, it continues to face challenges in mitigating climate change, improving urban air quality, managing waste, and protecting water resources. The surrounding countries of Italy may also contribute to pollution levels in the region, but the specific impact of each neighbouring country on Italy's environment is not readily available.

Italy's surrounding countries and their pollution levels

Italy has been facing air pollution problems, especially in the north, where a lot of heavy industries are situated. During the 1990s, Italy was the tenth-largest producer of carbon dioxide (CO2). Heavy traffic and congestion in large metropolitan areas are also sources of pollution, although smog levels have decreased since the 1970s and 1980s. In 2019, Italy's average level of air pollution was 61 US AQI, ranking it 59th out of 98 countries. The concentration of the pollutant PM2.5 was 17.09 µg/m³ in 2019 and 14.95 µg/m³ in 2018. The sharp rise in PM2.5 concentrations is particularly concerning as it causes respiratory and cardiac problems and has been attributed to over 9% of deaths among Italians over 30.

In January 2020, several Italian cities and towns introduced temporary traffic restrictions to reduce emissions, including Milan, which was surrounded by mountains that trapped air in the valley, and the Tuscan city of Florence, which banned highly polluting vehicles. In December 2017, Milan and Turin, two of the larger northern cities with some of the worst air pollution in Europe, introduced traffic restrictions to improve air quality.

While I could not find specific comparisons between Italy and its neighbouring countries, Italy was considered one of the most highly polluted places in Western Europe in January 2020. However, it is worth noting that Italy is taking steps to address climate change and air pollution. For example, Rome now has the largest mural in Europe painted with smog-eating paint, which eliminates dangerous pollutants like nitrogen and sulphur oxides.

Italy's surrounding countries include France, Switzerland, Austria, Slovenia, and Croatia. France, for example, has implemented various measures to reduce air pollution, including the Paris Agreement, which aims to combat climate change, and the Energy Transition Law, which sets targets for renewable energy and energy efficiency. Switzerland has a strong environmental record and is known for its sustainable practices, with a focus on recycling and waste management. Austria has a reputation for its commitment to environmental protection and renewable energy, while Slovenia and Croatia are also taking steps towards sustainability and reducing their environmental impact. While these countries may have different pollution levels, they are all facing the impacts of climate change and are working towards creating a more sustainable future.

Italy's environmental challenges

Italy faces a multitude of environmental challenges, which have far-reaching consequences for its ecosystems, biodiversity, and inhabitants. Here is an overview of Italy's environmental challenges:

Air Pollution

Italy, particularly its industrialised northern regions, struggles with air pollution. Cities like Milan, Turin, and Rome frequently exceed air quality standards due to vehicular emissions, industrial activities, and agricultural practices. The high number of cars, prevalence of diesel vehicles, factories, and power plants all contribute to the high levels of toxins and particulate matter in the atmosphere. This has detrimental effects on human health, ecosystems, and the climate, exacerbating issues like biodiversity loss and climate change.

Water Pollution

Italy's water bodies, including rivers and coastal waters, face significant pollution from agricultural runoff, industrial waste, and untreated sewage. This contamination of water with harmful substances has adverse effects on aquatic life and water quality, further contributing to the degradation of coastal and marine environments.

Waste Management

Italy grapples with waste management issues, especially in its southern regions. Some areas, like the Campania region, face critical situations regarding the disposal of municipal and hazardous waste. This has led to illegal dumping, harming both the environment and public health. Additionally, challenges in waste management contribute to environmental degradation and occasional waste crises.

Climate Change Impacts

Italy, as a peninsula and island nation, is vulnerable to the impacts of climate change. Rising sea levels, increased frequency of extreme weather events, and changes in precipitation patterns are causing more frequent droughts and flooding. These events have severe consequences for agriculture, water supplies, and energy generation, affecting food security and livelihoods, especially in rural areas.

Land Degradation and Biodiversity Loss

Italy is experiencing significant land degradation due to deforestation, urban sprawl, and poor agricultural practices. This degradation affects biodiversity and reduces land productivity. Additionally, Italy's diverse ecosystems and wealth of flora and fauna are threatened by habitat destruction, pollution, and climate change, further exacerbating the loss of biodiversity.

Italy is taking steps to address these environmental challenges. They have implemented policies to promote waste reduction and separate collection and are actively pursuing environmental sustainability initiatives. However, much more needs to be done to mitigate the worst impacts and ensure a sustainable future for the country and its inhabitants.

Italy's marine coastal zones and biodiversity

Italy has 7,600 km of coastline, the fifth longest in Europe and 14th longest globally. The country has 27 Marine Protected Areas, with two additional "Submerged Archaeological Parks", totalling 228,000 hectares of protected marine areas and 700 km of protected coastline. These areas are typically subdivided into Zones A, B, and C, each with a different level of protection.

Some of Italy's Marine Protected Areas include the Underwater Archaeological Park of Baia, the Torre Guaceto Nature Reserve, the Capo Rizzuto Marine Protected Area, and the Plemmirio Nature Reserve. The Capo Rizzuto Marine Protected Area, covering almost 15,000 hectares, is the largest in Italy. It is known for its red and white beaches, crystal-clear sea, and flourishing marine flora and fauna. The Plemmirio Nature Reserve covers 2,000 hectares along the eastern coast of Sicily and is popular for snorkelling, diving, and walking trails.

Italy's coastal dune systems, despite covering small areas, can host a high level of biodiversity. However, human pressure on these coastal zones has increased significantly in the last 50 years, leading to direct habitat loss and the rapid extinction of unique species. Climate change has also impacted Italy, with rising temperatures, heatwaves, and changing precipitation patterns causing droughts, flooding, and disruptions to agriculture, water supplies, and energy generation.

To address these challenges, Italy is taking steps towards renewable energy, sustainable infrastructure, and climate-resilient agriculture. By investing in these areas, Italy has the potential to create new jobs, stimulate economic growth, and become a leader in the transition to a low-carbon economy.

Italy's climate change mitigation efforts

Italy is the third-largest consumer of energy in the European Union, after Germany and France. The country's most used energy sources are petroleum products and natural gas, which is imported. Transportation is the sector most responsible for greenhouse gas emissions in Italy.

Italy is highly aware of the crucial importance of addressing climate change. The country has increased its efforts to produce and consume more renewable or "green" energy to reduce carbon emissions. Italy is one of the world's largest producers of renewable energy. Wind and solar power grew rapidly between 2010 and 2013, and the country has been on a downward curve for emissions since 2008. In 2019, Italy's emissions were under 500 million tonnes of CO2, down from 600 million tonnes in 2008.

Italy has also joined the Climate and Clean Air Coalition to Reduce Short-Lived Climate Pollutants, which aims to reduce emissions of SLCPs and integrate national efforts with international activities. As part of the Coalition, Italy supports projects in developing countries and has adopted measures to reduce HFC emissions, such as instituting a certification system for handling these gases. Italy is also actively promoting initiatives to reduce black carbon emissions from the transport sector, such as low-impact fuels and ecological vehicles for goods distribution. Through the Sustainable Mobility Fund, Italy has co-financed 187 projects worth a total of 195 million euros.

Italy is also investing in climate-resilient agriculture and sustainable infrastructure. The country was the first to make education on climate change compulsory and has included the "protection of the environment, biodiversity, and ecosystems" in its constitution. Italy is part of the Paris Agreement, the EU Adaptation Strategy, and a treaty with France for reinforced bilateral cooperation on sustainable development, defense of the climate, and protection of the Mediterranean and the Alpine Arc.

However, Italy is facing widespread impacts of climate change, including rising temperatures, melting glaciers, and an increase in extreme weather events such as heatwaves, droughts, and flooding. The country is particularly vulnerable to the impacts of climate change due to its long coastline and reliance on imported energy.

Italy's air pollution and health hazards

Italy is one of the countries at the forefront of extreme weather events and other consequences of the climate crisis, which is having a significant impact on the country, from public health to agriculture and infrastructure. According to the World Health Organization, exposure to air pollution causes 4.2 million deaths worldwide each year, and at least 600,000 children suffer from acute respiratory infections due to toxic air.

In Italy, the average level of air pollution in 2019 was 61 US AQI, ranking it 59th out of 98 countries. The concentration of the pollutant PM2.5 was 17.09 µg/m³ in 2019, up from 14.95 µg/m³ the previous year. This fine particulate matter is particularly harmful, causing respiratory and cardiovascular problems, and is linked to over 9% of deaths of Italians over 30 years of age.

The main sources of air pollution in Italy include the burning of fossil fuels, biomass combustion for heating, industrial emissions, agricultural activities, and waste incineration. The ILVA Taranto steel plant was Italy's largest carbon polluter in 2021, emitting 9.65 million metric tons of CO₂. The country's tourism industry also contributes to pollution, with an increase in waste and emissions during peak travel seasons.

The impact of climate change in Italy is evident in the rising temperatures, with average annual temperatures increasing by 1 degree Celsius in the last century, and more frequent and intense heat waves. This has led to increased use of air conditioning, straining energy grids and causing blackouts in major cities. Without significant emissions reductions, temperatures in Italy are projected to rise further, intensifying the frequency and severity of extreme weather events.

Italy is taking steps to address climate change, with opportunities to invest in renewable energy, sustainable infrastructure, and climate-resilient agriculture. However, more urgent action is needed to mitigate the worst impacts and ensure a safer and more sustainable future for the country.
