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.
