PROTESTS

Climate activists turn landmark Rome fountain black

Climate activists in Italy turned a Baroque-style fountain at the foot of Rome's Spanish Steps black on Saturday, in a protest they said evoked an "end of the world" scenario.

Three activists from the Italian anti-climate change organisation Last Generation (Ultima Generazione) poured a vegetable-based carbon liquid into the landmark 17th-century fountain, known to Romans as La Barcaccia, before being escorted away by police.

The fountain, in the shape of a boat, was designed by famed Italian sculptor Pietro Bernini.

Popular tradition has it he was inspired by the discovery in 1598 of a boat in the square after it was washed inland by a flooding Tiber river, Last Generation said.

Turning the water black “foreshadows the ‘end of the world’ scenario we are heading for, as we increasingly step on the accelerator: drought alternating with devastating floods, which will put an end to life on Earth, along with heat waves,” it said in a statement.

Last Generation began carrying out peaceful but disruptive protests in Italy last year ahead of the general election, urging politicians from all parties to make climate change their priority.

The protests in Italy are part of a series of actions across Europe to focus attention on climate change.

Activists have thrown soup, cake, mashed potatoes or washable paint at heritage and culture sites and artworks in museums.

Why is air pollution in northern Italy so bad?

The Po Valley, a 48,000-square-kilometre area straddling Piedmont, Lombardy, Veneto and Emilia-Romagna, is the worst area in western Europe and among the worst in the entire continent for air pollution, according to new data.

The study, compiled by academics at Utrecht University and the Swiss Tropical and Public Health Institute, has found that more than a third of the people living in the valley and surrounding areas breathed air whose concentrations of PM2.5 particles– were four times the World Health Organization’s guideline limit of 5 micrograms a cubic metre.

This placed the Po Valley, or Pianura Padana, behind Serbia and North Macedonia, where more than half of the local population was found to be exposed to PM2.5 levels that were at least four times the WHO figure.

Mapping of the data showed the northern Italian region in stark contrast to all other areas of Western Europe.

No area of France or Spain saw average readings higher than 14 micrograms a cubic metre, while in Sweden PM2.5 levels did not exceed 10 micrograms.

Why is PM2.5 bad?

PM2.5 (fine particulate matter) is regarded by scientists as one of the most dangerous air pollutants for human health, as a growing body of research proves it’s responsible for a wide range of health problems, from lung and heart disease to diabetes and cancer.

According to the European Environment Agency (EEA), exposure to PM2.5 was responsible for some 238,000 premature deaths across Europe in 2020.

Further, Italy’s National Institute of Health has estimated that the pollutant may be responsible for over 50,000 early deaths in the country every year.

Where in northern Italy is the situation most critical?

Lombardy’s Milan, Cremona and Monza were the three worst European provinces for air pollution in 2022, as average annual PM2.5 levels exceeded 21 micrograms per cubic metre in all cases, according to research conducted by the European Data Journalism Network in partnership with German broadcaster Deutsche Welle.

As for the current year, average concentrations of PM2.5 in Milan (Lombardy), Verona and Padova (Veneto) were at least four times the WHO limit for multiple consecutive weeks in the first quarter of 2023.

Data about other pollutants are equally alarming as a 2023 report from Italy’s environment watchdog Legambiente found that, of the ten worst cities for PM10 (coarse particulate) pollution, nine were in the Po Valley, with Turin, Milan and Cremona topping the chart.

Why is the Po Valley so heavily polluted?

A number of different factors contribute to the Po Valley being one of the worst places for air pollution in Europe, according to experts.

Firstly, the Pianura Padana is among the most heavily industrialised areas on the continent: Lombardy is the top industrial region in the EU, with Veneto (6th) and Emilia Romagna (9th) also figuring in the top ten.

This translates to high levels of emissions – mainly nitrogen oxides – derived from industrial combustion and manufacturing or refinery processes.

But with over 23 million residents (around 40 percent of the national population), the Po Valley is also a very densely populated area.

Lombardy’s population density (417 inhabitants per square kilometre) is more than two times the national average (195 people/km²) and nearly four times the average EU figure (109 people/km²).

This results in very high local concentrations of pollutants (especially particulate matter and nitrogen oxides) derived from domestic heating and road traffic.

The region’s weather conditions and the influence of nearby mountain ranges also “contribute significantly” to pollution, according to Flavio Galbiati, a meteorologist for Meteo Expert.

The Alps and Apennines surrounding the Po Valley “affect the wind regime, whose intensity is generally very weak”. This contributes to relatively lengthy periods of air stagnation.

Secondly, the area frequently experiences a phenomenon known as ‘thermal inversion’ during the cold months: the ‘layer’ of air close to the ground becomes colder (and heavier) than the layer above it, which prevents it from rising through the atmosphere.

This creates smog, or, as Galbiati describes it: a “clog that prevents air circulation, trapping pollutants close to the ground, where their concentration can only increase day after day.”

What does the future look like?

While the area’s geographical features cannot be changed, the transport, agriculture and heating sectors could all be regulated to reduce pollution and protect public health according to Legambiente.

Notably, given that “the efficacy of traditional policies against pollution in the Po Valley regions has been decreasing for years”, the area needs a “tight programme of ecological and energy transition”, says Damiano Di Simine, scientific coordinator at Legambiente Lombardia.

This would include a gradual switch to fully electric public transport, the phase-out of combustion vehicles and heating devices using non-renewable sources, and environmentally-friendly city planning.

But regional authorities in the Po Valley have so far failed to take meaningful and decisive steps, voicing concerns that many of the required measures would hit the local economy as the area produces 40 percent of Italy’s GDP.

Last May, the regional heads of Veneto, Lombardy, Piedmont and Emilia Romagna all opposed new EU directives setting out stringent emission limits and environmental targets to be met by 2030.

In particular, Lombardy’s president Attilio Fontana called the new guidelines “unreasonable”, saying that, if implemented, they would mean “closing 75 percent of manufacturing activities, blocking the circulation of three quarters of current vehicles” and outlawing “more than 60 percent of our heating systems” in what would be a “shutdown of the Po Valley”.

Northern regions’ hostility towards European air quality policies has so far mirrored the national government’s stance on the issue.

Earlier this year, Rome tried and failed to block EU plans to ban the sale of new cars running on fossil fuels by 2035, with deputy premier and transport minister Matteo Salvini branding the rules “madness” that would “destroy thousands of jobs for Italian workers”.

This week, EU legislators watered down plans to tighten vehicle emission standards from 2025, following lobbying from a united front of eight member states including Italy.

This was hailed as a victory by Business and Made in Italy Minister Adolfo Urso, who said “reason had won over ideology” and Europe had sidestepped “a chasm for the [car] industry, business and workers”.
