Dirty air is killing Europeans and costing trillions. These cities prove change is possible
From London's ULEZ to Sofia's clean air zone, European cities are proving that cleaner air is achievable – but there's still much work to do.
In 2023, air pollution claimed nearly eight million lives worldwide, according to Breathe Cities, a global campaign fighting urban air pollution. The health toll is estimated to cost €7.12 trillion annually, equivalent to about six percent of global GDP, as highlighted by Dr María Neira, formerly from the World Health Organization.
Pollution harms the body in unseen ways, with pollutant particles affecting every organ, including the brain, leading to issues like cognitive decline and diseases such as Parkinson's, Alzheimer's, and dementia.
Paula Radcliffe, a former Olympic runner, experienced the consequences firsthand. Diagnosed with exercise-induced asthma at age 14, she felt headaches, nausea, and impaired vision after running in Beijing's polluted air. Radcliffe notes that dirty air impacts children's brain development and school performance, too.
Breathe Cities collaborates with 16 cities globally to enhance access to air quality data and promote clean air policies. London has reduced deaths linked to toxic air by approximately 40 percent since implementing its Ultra Low Emission Zone (ULEZ) and other clean air initiatives, according to an independent study by Imperial College London.
Sofia, Bulgaria, faces significant air pollution issues, with traffic and wood-burning heating as the primary sources. In 2023, the city was identified as one of Europe's most polluted, with Dr Kostadin Kostadinov from the Medical University of Plovdiv estimating around one million premature deaths annually attributable to air pollution.
Following a legal challenge by environmental groups and residents, Sofia instituted a low emission zone limiting traffic and upgrading domestic heating, resulting in evidence of reduced pollution levels, according to Ivaylo Hlebarov, an air quality consultant for Sofia Municipality.
However, the low emission zone operates only for three months annually, a decision driven by political factors. Hlebarov emphasizes that traffic-related nitrogen dioxide pollution remains consistent throughout the year, necessitating year-round implementation. Bulgaria experiences high rates of cardiovascular disease, stroke, and cancer, all strongly linked to air pollution, despite limited local research on the topic.
The future outlook for Europe's air pollution crisis hinges on political will rather than technological solutions, according to Dr Neira. She attributes resistance from fossil fuel and transport industries as a barrier as cities advocate for renewable energy and sustainable mobility. Climate change is anticipated to exacerbate the problem.
Breathe Cities is currently planning a second phase of its efforts, expanding support to additional communities while building upon the progress already made in cities like London, Sofia, and others participating in the initiative.
