• The volume of fine particulate matter in Europe’s air has been declining over the past decade but remains above recommended levels.
  • Air pollution kills millions of people each year, with fine particles irritating the lungs and exacerbating existing cardiovascular and respiratory diseases.
  • Europe’s cleanest air is in Estonia, Finland and Sweden.

The volume of fine particles in Europe’s urban air has been gradually decreasing over the past decade. This is good news: pollutants in the air, such as fine particulate matter, reduce people’s life expectancy and can aggravate many chronic respiratory or cardiovascular diseases. This means that the air pollution in Europe has decreased.

The annual mean concentration of fine particles (PM2.5) in urban areas of the EU was 19.4 μg/m3 in 2011. This has gradually decreased to 12.6 μg/m3 in 2019, according to the latest statistics released by the EU statistics agency, Eurostat.

But even though these pollutants sit within air quality thresholds, there are still a number of hotspots in Europe where air pollution is higher. And despite the improvement, 2019 levels are still above those recommended by the World Health Organization (10 μg/m3 annual mean).

Effects of air pollution in Europe

Among the EU Member States, the annual mean concentration of fine particles is highest in urban areas of Bulgaria, and Poland, Romania and Croatia.

The WHO estimates that air pollution kills 7 million people worldwide each year.

Fine particles with a diameter of less than 10 micrometres (PM10) can be carried deep into the lungs, causing inflammation and exacerbating heart and lung problems.

Even smaller particles – those with a diameter of less than 2.5 micrometres (PM2.5) – can travel even further into the lungs, leading to more severe health consequences.

What’s the World Economic Forum doing about climate change?

Climate change poses an urgent threat demanding decisive action. Communities around the world are already experiencing increased climate impacts, from droughts to floods to rising seas. The World Economic Forum's Global Risks Report continues to rank these environmental threats at the top of the list.

To limit global temperature rise to well below 2°C and as close as possible to 1.5°C above pre-industrial levels, it is essential that businesses, policy-makers, and civil society advance comprehensive near- and long-term climate actions in line with the goals of the Paris Agreement on climate change.

The World Economic Forum's Climate Initiative supports the scaling and acceleration of global climate action through public and private-sector collaboration. The Initiative works across several workstreams to develop and implement inclusive and ambitious solutions.

This includes the Alliance of CEO Climate Leaders, a global network of business leaders from various industries developing cost-effective solutions to transitioning to a low-carbon, climate-resilient economy. CEOs use their position and influence with policy-makers and corporate partners to accelerate the transition and realize the economic benefits of delivering a safer climate.

Urban hotspots for air pollution in Europe

Within Europe, annual mean PM2.5 concentrations are highest in urban areas of Bulgaria (19.6 μg/m3) and Poland (19.3 μg/m3), followed by Romania (16.4 μg/m3) and Croatia (16.0 μg/m3).

Better air quality is found in urban areas of Estonia (4.8 μg/m3), Finland (5.1 μg/m3) and Sweden (5.8 μg/m3), which have the lowest concentration of these fine particles.

The impact of COVID-19

With a succession of lockdowns around the world over the past 18 months, air in some of the world’s biggest cities has been visibly clearer at times.

Factory closures and fewer flights and cars on the roads had a huge impact on curbing air pollution in Europe. Measurements taken by the European Space Agency’s Sentinel-5P satellite show that during late January and early February 2020, levels of nitrogen dioxide over cities and industrial areas (air pollution) in Europe were significantly down on 2019 levels.

But a year on, as lockdowns started to ease, the same satellite is showing that air pollution is rebounding to pre-COVID levels.

At the June 2021 G7 Summit, leaders committed to step up their actions to combat climate change. They reaffirmed their pledge to raise $100 billion a year to help poorer nations cut emissions. Agreement was also reached to put biodiversity and the environment at the heart of COVID-19 recovery plans.
