A comprehensive study by the European Environment Agency has underscored the pervasive threat of air pollution to worldwide populations, particularly in urban centres, linking both short- and long-term exposure to a spectrum of diseases.

The World Health Organization (WHO) has long emphasised the intricate connections between air pollution and various health conditions, ranging from strokes and chronic obstructive pulmonary disease to cancer and Alzheimer’s. The study highlights fine particulate matter (PM2.5) as a significant concern, affecting a staggering 97% of urban dwellers above WHO guidelines in 2021. Notably, children and adolescents face heightened vulnerability due to ongoing development, with limited ability to influence air quality policies or protect themselves from the deleterious effects. In 2020, approximately 238,000 premature deaths in the EU were attributed to PM2.5, revealing a noteworthy 45% decrease from 2005. Energy consumption, particularly in residential, commercial, and institutional sectors, emerged as the primary source of particulate matter in 2020, with emissions of PM10 and PM2.5 dropping by 30% and 32%, respectively, between 2005 and 2020.
Responding to the alarming scenario, the WHO and the European Union (EU) have introduced stringent air quality guidelines and standards. The EU’s commitment to the zero-pollution action plan aims to reduce premature deaths by over 55% by 2030, compared to 2005, and minimise the impact on biodiversity. Stricter air quality standards are deemed crucial in achieving the objectives outlined in Europe’s Beating Cancer Plan. Encouragingly, the trend from 2005 to 2020 indicates a 33% reduction in premature deaths attributed to PM2.5 exposure in the EU-27. If this positive trajectory continues, the zero pollution target could be attained by 2032, marking a significant milestone in the ongoing battle against the adverse health effects of air pollution.
