The cleanest city in the Philippines, based on 2023 air quality data, is Calamba, Calabarzon.
Understanding "Cleanest City" through Air Quality
When identifying the "cleanest city," it's crucial to specify the criteria used. In this context, "cleanest" refers to the city with the best air quality as measured by the Air Quality Index (AQI). A lower AQI score indicates cleaner air and less pollution.
Calamba's Air Quality Status
In 2023, Calamba in the region of Calabarzon recorded an Air Quality Index (AQI) of 46. This score signifies good air quality, making it stand out as having the best air among monitored cities in the Philippines during that period. Good air quality generally means that the air pollution poses little or no risk to public health.
Comparison with Other Cities
To provide perspective, it's helpful to compare Calamba's air quality with other urban centers. For instance, in the same year, Mandaluyong in the National Capital Region (NCR) registered an AQI of 69, indicating a higher level of air pollution compared to Calamba. This difference highlights the varying air quality conditions across different Philippine cities.
Here’s a snapshot of selected cities based on their 2023 air quality data:
| City | Region | 2023 Air Quality Index (AQI) | Status (Based on AQI) |
|---|---|---|---|
| Calamba | Calabarzon | 46 | Cleanest (Good Air) |
| Mandaluyong | NCR | 69 | Most Polluted |
A lower AQI score (like Calamba's 46) is desirable, indicating healthier air. Conversely, a higher AQI score (like Mandaluyong's 69) suggests more significant air pollution levels.
