Only Few Countries Have Clean Air

• Out of 143 countries, only 13 countries meet WHO air quality standards
• The cleanest air countries are: Australia, New Zealand, Finland, Iceland, Estonia, Sweden, Norway, Grenada, Mauritius, Bahamas, Barbados, and Canada.
• WHO safe limit for PM2.5: 5 µg/m³ annually

What the Report Says

The report states that air pollution remains a major global health and environmental risk. It highlights that most countries continue to record PM2.5 levels above safe limits, exposing large populations to unhealthy air.

It also points out that air quality data is based on a combination of government monitoring stations and low-cost sensors, providing a broad picture of pollution levels worldwide.

The findings indicate that without strong action, air pollution will continue to impact public health, environment, and overall quality of life across countries, including India.
