In 2024, only seven countries met the World Health Organization’s (WHO) air quality guidelines, highlighting significant global pollution challenges.
Countries meeting WHO qir quality standards:
- Australia
- New Zealand
- The Bahamas
- Barbados
- Grenada
- Estonia
- Iceland
Most polluted countries:
- Chad
- Bangladesh
- Pakistan
- Democratic Republic of Congo
- India
These nations recorded average PM2.5 levels exceeding WHO guidelines by more than 15 times.
The US State Department has ceased its global air quality monitoring program, which provided crucial data, especially for developing countries lacking their own monitoring infrastructure. This decision raises concerns about future data availability and air quality management in affected regions.
Significant data gaps persist, particularly in Asia and Africa, hindering comprehensive global air quality assessments. The discontinuation of the US monitoring program exacerbates these challenges, underscoring the need for enhanced local monitoring solutions.
Air pollution remains a leading risk factor for mortality worldwide, second only to high blood pressure. Elevated PM2.5 levels are linked to severe health issues, including respiratory and cardiovascular diseases.
The global community must prioritise air quality monitoring and management. Investments in local monitoring infrastructure, especially in developing countries, are essential to address pollution and protect public health.
