Air Pollution and Lung Cancer in Europe: What the Evidence Now Shows
In April 2026, the Union for International Cancer Control (UICC) and The George Institute for Global Health published Clean Air in Cancer Control: An Overview of the Evidence - the most comprehensive report to date on what we know about air pollution and cancer. Drawing on 42 systematic reviews and meta-analyses, the findings are stark.
For those of us working in lung cancer advocacy, some of the findings confirm what the science has pointed to for years. Others should prompt urgent attention from policymakers across Europe and beyond.
What the report found
The International Agency for Research on Cancer (IARC) classified outdoor air pollution as a Group 1 carcinogen back in 2013. That classification has never been in doubt. What this new report adds is scale and scope.
More than 434,000 lung cancer cases each year are attributed to air pollution globally. Long-term exposure to fine particulate matter - PM2.5 - raises an individual’s overall risk of developing cancer by 11%, and their risk of dying from cancer by 12%. And the evidence now points beyond the lungs: air pollution is linked to increased risk across multiple cancer types.
These are not marginal findings. They represent a preventable burden on a massive scale.
The European inequality story
In Europe, overall air quality has improved over recent decades and that is worth acknowledging. Deaths in the EU attributable to PM2.5 fell by 45% between 2005 and 2022. But progress has not been shared equally, and the gap is widening rather than closing.
Eastern and south-eastern European countries carry the heaviest health burden from air pollution on the continent. PM2.5 levels in some parts of Eastern Europe are several times higher than in the west. Bosnia and Herzegovina recorded a median PM2.5 of 32 µg/m³ in 2022. Serbia recorded 23 µg/m³. In contrast, Iceland recorded 3 µg/m³, Finland and Sweden 5 µg/m³ each.
The EU’s own revised Air Quality Directive, adopted in 2024, sets a new limit of 10 µg/m³ for PM2.5 by 2030 - a standard that much of Eastern Europe currently exceeds by a significant margin.
For people living with lung cancer in these regions, this is part of a broader picture of compounded disadvantage: higher pollution exposure, less access to specialist care, lower rates of molecular testing, and greater delays in diagnosis. Air quality inequality is cancer inequality.
Why this matters for lung cancer specifically
Lung cancer remains the leading cause of cancer death in Europe. It is also the cancer most directly and clearly linked to air pollution exposure. For people who have never smoked (a growing proportion of those diagnosed) air pollution is among the most significant known risk factors.
The UICC report shows that lung cancer is not solely a disease of individual behaviour. It is also a disease of environment, policy failure, and systemic inequality. Framing it otherwise does a disservice to the people living with it and to the communities most exposed.
What needs to happen
The revised EU Air Quality Directive creates a legal framework for change. But legislation only delivers if it is implemented, monitored, and enforced - and if the communities most affected have a voice in how that happens.
At Lung Cancer Europe, we believe people living with lung cancer and those at highest risk must be part of the conversation on air quality policy. The evidence base is now unambiguous. The question is political will.
We welcome the UICC report and urge policymakers across Europe - particularly in the regions where exposure remains highest - to treat air quality as a lung cancer issue, not a separate one.
