The air quality is experiencing sustained deterioration globally. This is indicated by an analysis conducted by the Swiss company IQAir that covered 9,446 cities in 143 countries.
Additionally, the report, titled ‘2025 World Air Quality Report’, warns that human-induced climate change is a key factor. Consequently, extreme events are intensifying.
Therefore, air pollution is established as an urgent environmental problem. Likewise, its effects impact both health and the economy.
A world far from safe levels
Only a small group of countries comply with international recommendations. Among them are Andorra, Estonia, and Iceland.
Additionally, globally, Australia, Barbados, Bermuda, French Polynesia, Grenada, New Caledonia, Panama, Puerto Rico, Réunion, and United States Virgin Islands are included.
Consequently, 130 of the 143 countries analyzed exceed safe levels. Therefore, the issue has a global reach.
On the other hand, among the most polluted countries are Pakistan, Bangladesh, Tajikistan, Chad, and the Democratic Republic of the Congo. Thus, a strong environmental inequality is evident.
Fires, dust, and extreme phenomena worsen pollution
During 2025, wildfires were one of the main sources of pollution. Added to this were dust storms and severe weather events.
Additionally, these phenomena are linked to the intensive use of fossil fuels. Consequently, the presence of harmful particles in the air increases.
Likewise, the economic impacts were also significant. Therefore, million-dollar losses associated with climate disasters were recorded.
On the other hand, heatwaves, floods, and droughts intensified the problem. Thus, environmental deterioration becomes increasingly complex.
Fine particles and health risks
PM2.5 particles represent one of the greatest health risks. Their microscopic size allows them to easily enter the body.
Additionally, they can penetrate the lungs and reach the bloodstream. Consequently, they cause respiratory and cardiovascular diseases.
Likewise, these particles are associated with serious pathologies. Therefore, their control is essential for public health.
On the other hand, international standards establish safe limits. However, most countries fail to meet them.
How clean air improves quality of life
Access to clean air has direct effects on human health. Firstly, it reduces respiratory and cardiovascular diseases.
Additionally, it improves general well-being and sleep quality. Consequently, it contributes to a healthier life.
Likewise, environments with less pollution favor child development. Therefore, they positively impact growth and learning.
On the other hand, clean air also benefits ecosystems. Thus, it improves agricultural productivity and biodiversity.
Finally, ensuring good air quality reduces healthcare costs. Consequently, it becomes a key investment for sustainable development.
