Based on recent data, Singapore's air quality performs relatively well within the Southeast Asian region.
While air quality is a complex issue influenced by various factors, a reference dated October 18, 2024, indicates that Singapore holds a strong position compared to its regional neighbors. Specifically, the information states:
However, in the region of Southeast Asia, Singapore performed relatively well, achieving the second best air quality status in the region behind the Philippines.
This suggests that among countries in Southeast Asia, Singapore's air quality is considered good, ranking just behind the Philippines.
Understanding Air Quality
Air quality is typically measured by the concentration of pollutants like particulate matter (PM2.5, PM10), ozone, nitrogen dioxide, sulfur dioxide, and carbon monoxide. High levels of these pollutants can impact health and visibility.
Factors Influencing Singapore's Air Quality
Singapore's air quality can be affected by:
- Local Emissions: Vehicle traffic, industrial activities, and power plants contribute to local pollution.
- Transboundary Haze: Seasonal burning in neighboring countries, particularly during the dry season, can significantly impact Singapore's air quality, sometimes leading to haze events.
- Weather Patterns: Wind direction and speed can carry pollutants into or away from the island.
How Singapore's Air Quality Ranks Regionally
As highlighted by the reference:
| Country | Southeast Asia Ranking (Based on Reference) |
|---|---|
| Philippines | 1st (Best) |
| Singapore | 2nd |
| Other SE Asia | Lower than Singapore |
This ranking indicates that, from a regional perspective, Singapore's efforts in managing air quality place it in a favorable position.
While local conditions can fluctuate daily and seasonally (especially during haze periods), Singapore's overall performance within Southeast Asia suggests a relatively better air quality status compared to many other countries in the region.
