This pivotal legislation introduces stricter limits on major air pollutants such as particulate matter (PM2.5, PM10), nitrogen dioxide (NO2), and ozone (O3), aligning it more with the World Health Organization (WHO)'s 2021 air quality guidelines (AQGs).

Air pollution poses a severe global public health threat, with nearly 99% of the world鈥檚 population breathing air that surpasses WHO limits, leading to increased mortality and morbidity. The promise substantial reductions in air pollution levels, addressing urgent public health challenges and aiming to protect vulnerable populations including children, the elderly, and those with respiratory conditions like chronic obstructive pulmonary disease (COPD).

The GAP research group has consistently shown that long-term exposure to low-level of air pollution significantly increases and risks associated with .聽Lifelong exposure to air pollution鈥攆rom childhood and adolescence to adulthood鈥攈as been linked to a higher risk of . Additionally, parental exposure to air pollution may increase , while exposure during pregnancy is associated with .

The GAP research group welcomes these changes, which echo our findings that cleaner air can significantly improve public health. This legislation marks a significant stride towards cleaner air and a healthier future for all.
