In 2022, South Asia saw a decline in pollution levels, thanks to above normal rainfall patterns. However, the region still accounts for 45 percent of total life years lost globally due to high pollution. Bangladesh, India, Nepal, and Pakistan are among the most polluted countries in the world, with residents exposed to particulate pollution levels significantly higher than at the start of the century.
Bangladesh is the most polluted country in South Asia, with pollution levels far exceeding WHO guidelines. In India, the large population exposed to air pollution faces a significant health burden. The United States has made progress in reducing pollution, but wildfires in California remain a concern.
In Europe, pollution levels have decreased since 1998, but a large portion of the continent still falls short of acceptable standards. To address this issue, it is crucial for countries to set ambitious standards, enforce policies, and improve monitoring mechanisms.
Government transparency in pollution monitoring is essential to combatting air pollution effectively. By increasing awareness and demand for data, countries can work towards cleaner air and healthier populations.
