Faro is least polluted city in European Union

Faro has lowest average concentration of fine particles in European Union

A study based on data from the European Environment Agency has found Faro to be the least polluted city in the European Union.

The data was compiled by website Toute l’Europe and shared by German data website Statista, which listed the 10 European cities which remained below the recommended level of fine particles by the World Health Organisation.

“Fine particles with a size of less than 2.5 micrometers (PM2.5), are released into the atmosphere during the combustion of fossil fuels, primarily for heating and transportation, as well as during the use of certain pesticides,” Statista says.

“According to the World Health Organization (WHO), air pollution is responsible for over four million deaths each year, and prolonged exposure to fine particles could cause or worsen various health problems such as cardiovascular disorders, obesity, and diabetes. Since 2021, the WHO has recommended a maximum level of five micrograms of PM2.5 per cubic meter of air for prolonged exposure. In Europe, almost all cities exceed this threshold,” it adds.

However, there are ten cities in Europe which remained below the recommended level of fine particles.

“In 2021-2022, the least polluted European city in the study was Faro, Portugal, where the average concentration of PM2.5 in the air was only 3.7 μg/m³. Next were two Swedish cities, Umeå (3.9 μg/m³) and Uppsala (4 μg/m³),” the website adds.

Funchal, the capital of the Portuguese archipelago Madeira, placed fourth on the list (4μg/m³), followed by Tallinn (Estonia), Tampere (Finland) and Reykjavik (Iceland), all with 4.3 μg/m³. The list is rounded off by two Swedish cities (Norrköping, 4.7 μg/m³, and Stockholm, 4.8 μg/m³) and one Estonian (Narva, 4.9 μg/m³).
